My New Weather Station

Getting the hyper-local weather information I crave.

I’ve always been interested in weather. Yes, I’m the kind of person who’d leave The Weather Channel on all day as background noise — in the days when they actually broadcast live weather information all day. And always know the most up-to-date weather sources. And have multiple weather apps on my mobile devices so I could check one against the other.

My Thirst for Weather Data

Not long after moving into my Arizona home in the late 1990s, I bought a solar powered wireless weather station. My future wasband mounted it on the roof of the shed near the horse corral and it beamed back weather information to a panel at my desk. For a while, I had it connected to a Windows PC I had — the software wasn’t Mac compatible in those days — and put live weather information on a Wickenburg website I ran. In 2003, when I got the fuel manager contract at Wickenburg airport, we moved the weather station there — it was far more reliable than the ancient setup in use. (Wickenburg now — finally — has an AWOS.) When I sold the contract, I included the weather station among the assets of the business. For all I know, it’s still there.

Although I didn’t miss the weather station much as life dragged on in Wickenburg, I definitely wished I had weather stations in Washington where I spent my summers starting in 2008. I get seriously tuned into the weather during cherry season, checking radar throughout the day and always knowing the forecast — from multiple sources — for the next three days. I dreamed of having portable, Internet-connected weather stations with accurate rain gauges and webcams so I could place them at each orchard when it was under contract. You see, I fly when it rains and knowing exactly when and how hard it was raining would benefit not only me, but also my clients. Trouble is, orchards aren’t usually in places where Internet access is available and the cost of a 3G/4G/LTE connection for each station was prohibitive.

Fast-forward to the late summer of 2013. I moved to a 10-acre lot I’d bought at the base of the basalt cliffs in Malaga, WA — a place I like to call Malaga Heights. From my aerie, I could see the weather coming and going from the southwest to northeast. With a new home base, I started thinking seriously about a weather station again.

Weather Station Options

Technology had moved forward in the ten years since I last owned a weather station. The main thing I wanted was the ability to monitor weather from anywhere in the world on my cell phone. I had some practical applications for this, but it was mostly just a desire to get hyperlocal weather information, live, anytime, from anywhere.

I did some research. I discovered that weather stations fell into four categories:

  • Basic home weather stations. These are the ones that put a panel in your house and one or more sensors outside that can broadcast data to the panel. I already had one of these — heck, I’ve had these forever. In 2013, when I was still living in my RV, it became extremely valuable for me to monitor temperatures during the winter at my water source and RV basement. But systems like these are extremely limited, not only in range but also in the available instruments. It’s usually just temperature, humidity, and barometric pressure.
  • Weather stations with limited connectivity. These are weather stations that have a full set of instruments for temperature, humidity, wind speed/direction, and rainfall, but they just send that information to nearby information panel. That’s what I had back in the early 2000s.
  • Weather stations with Internet connectivity. These are weather stations that have a full set of instruments for temperature, humidity, wind speed/direction, and rainfall, and they transmit data via the Internet, through wifi or a direct connection to a router. They often also transmit to a panel where the user can view data locally.
  • Weather stations with Internet connectivity and direct smartphone access. These are weather stations that have a full set of instruments for temperature, humidity, wind speed/direction, and rainfall, and can transmit data directly to the Internet as well as to a smartphone app. Again, they also often transmit to a panel where the user can view data locally.

My main goal was to be able to view current weather conditions for my home on my iPhone. This would make it possible for me to assess conditions for landing my helicopter, which lives in my garage. When I fly home and put it away, I need to land on a 9×9 platform parked on my driveway on the east side of my home. With very strong winds in the area, landing there is difficult — so difficult that I prefer to land at a secondary landing zone on the north side of my home. I can then wait until the wind dies down, fire the helicopter back up, and move it to the platform. I don’t have to do this often — I think I did it just twice in all of 2015 — but it’s nice to know what to expect at home before I arrive. What’s interesting is that when the wind is howling at the airport across the river, it’s often quite calm at my driveway. This is likely because of my home being sheltered on two sides by terrain. That’s one of the reasons I built it where I did.

So at first it looked as if I’d need that last type of weather station — the kind with an app to get the data on my phone. Unfortunately, the stations I found that met that criteria were quite expensive — in the $250+ range. And I really couldn’t justify the expense, especially when I seldom have a real need for that weather data. After all, I only take the helicopter out about 50 times a year and the streamers on poles on my deck offer a decent indication of wind conditions when I get here. (I also have an airport-style windsock, but I positioned it too far from my landing zone to be of any real use to me. Long story there.) Maybe I was just trying to use flying as excuse for a new weather station? Probably.

More research showed me that Internet-compatible weather stations could usually be set up with The Weather Underground website. I started exploring stations already online there. I found one down at Crescent Bar, not far from one of the orchards I provide cherry drying services to. I clicked a link to get more information about the Weather station there and learned that it was an Ambient Weather WS-1400-IP.

WunderMap of my area
The WunderMap of my area shows the personal weather stations (PWSs) in the area. I’ve marked the one in Quincy and mine as well as the official weather station at the airport.

I did some more research and found that two Ambient Weather stations would meet my needs if I went with the Weather Underground: that one and the Ambient Weather WS-1001-WIFI. The difference: the more expensive ($299) WS-1001 had a panel to monitor the weather inside the house and did not require an ethernet connection to my router while the less expensive WE-1400-IP ($159) could only be viewed from a Web page or app and required an ethernet connection to my router. Both had the same basic set of instruments and were equally easy to mount. Both also had a solar panel to keep the station’s batteries charged.

WS-1400-IP
The Ambient Weather WS-1400-IP includes outdoor weather instruments mounted together in one cluster; an indoor temperature, humidity, and pressure sensor; and an ObserverIP receiver that must be connected to a router. The iPad and iPhone in this marketing photo apparently indicate that data can be seen on mobile devices after registering the station with the Weather Underground.

I was fortunate in that I planned to mount the station at my shed, which was about 100 feet from my building. The line-of-sight receiver would go in the window overlooking the shed by my desk, which was less than two feet from my router. So as far as the connection went, requiring an ethernet cable was not an inconvenience. So the question was: Is the viewing panel worth the extra $140? My answer was no. I bought the WS-1400-IP.

Setting It Up

Mast Kit
This mounting kit is perfect for mounting on the side of a building.

I wanted to mount the weather station on the side of my shed, preferably with all instruments above the sprinkler head I’d put up there for fire season protection. That meant I needed some mounting hardware. Rather than trying to rig up my own mount — and likely being frustrated every step of the way — I spent another $44 (with shipping) on the Ambient Weather EZ-30-12 Mounting Kit with Mast.

Assembling the weather station was pretty easy. All I had to do was attach the wind vane at the top and one of the two short mounting poles on the bottom. The crimped pole fit snugly into the top of the mast that came with the mounting kit. I added two batteries to the indoor sensor and set it on a shelf near my desk. I then connected the receiver’s DC adapter to an outlet and ethernet cable to one of the four LAN ports on my router. Done.

The next step was to register my PWS on the Weather Underground. The weather station’s manual provides the URL. I had to create an account and then provide some information about my location and the weather station. At the end of the process, I received a weather station identifier.

Next, I had to use the IPTOOL application on my Mac (a Windows version is also available, of course) to locate the weather station’s receiver on my network and connect. That opened a configuration page in my Web browser. I used that to enter the station ID provided by the Weather Underground, as well as my password on that system. I could use other settings pages to provide the station model number, time zone settings, and units of measure. The Live Data page showed a rather user-unfriendly table of data collected from the station.

Configuration
The Weather Network configuration screen for my weather station lets me put in my Weather Underground ID.

Of course, since the weather station was still inside as I did all this, it registered inside temperatures and wacky wind readings as I moved it around. It was time to install it. I certainly didn’t want bad data going out on the network.

Installed Weather Station
The weather station is positioned just slightly above my fire season sprinkler head. I’ll need to raise it (or lower the sprinkler head) before next fire season.

My timing was good and bad: it had turned kind of nasty and was about to rain. That was good if I wanted to record rain information (which I did) but bad if I didn’t want to be on a ladder in the rain (which I didn’t). Still, I went out to the shed and climbed on the orchard ladder with a drill and impact driver and all the parts I needed. Within 15 minutes it was installed, level and pointed the right way. It’s not quite as tall as I’d hoped; in the future, I’ll likely add a second mast pole to raise it another three feet.

The rain started before I was done. I admit I was tickled to see it registering in the Live Data screen when I got inside. (I am such a weather geek.)

There was one more thing I needed to do — although I didn’t realize it until the next day. I thought the weather station would automatically adjust the pressure reading for my elevation of approximately 1550 feet above sea level. But when I realized that the readings were significantly lower than what they should have been, I did some additional research to see how I could fix it. The answer was to enter a relative pressure offset amount in the Calibration page of the weather stations settings. To do this, I needed an accurate pressure reading. I waited until the automated weather observation system at the airport just three miles away across the river updated and calculated the amount of offset to enter. I plugged that figure into the right box, updated the settings, and was good to go.

Viewing Weather Data

Weather Station Data
Here’s a snapshot of the display for my weather station as I wrote this blog post.

Although the Weather Underground claims it can take up to 24 hours to display a PWS on its site, mine was visible within an hour. It’s got its own page, which can be viewed by anyone at any time; I called it Malaga Heights. Here’s a screenshot of what you might see if you go to that link.

As you can see, there’s a lot of data, including current conditions pulled right from my PWS, sunrise and sunset times, moon information, and a radar map of my area. The current conditions are updated regularly; if you keep watching, you’ll see it change, especially if the wind is variable.

The weather history section summaries and graphs weather information for the day or a period you choose. As you can see, the temperature has been pretty steady on this overcast day, the wind really kicked up a few hours ago, and the pressure is falling. Solar radiation is likely measured for the solar cells on the station; it always rises after sunrise and drops back to zero by sunset.

WunderStation App on iPad
The WunderStation app on my iPad.

All of this information is also available in the various Weather Underground apps you can install on smartphones and tablets. For example, the WunderStation app on my iPad displays rearrangeable tiles of data that update automatically. I can even set up multiple PWSes in the app and switch from one to another with a swipe. Similarly, the Wunderground app on my iPhone displays information about any PWS, including my own. Both apps are free, and if you’re a Weather Underground member — a bargain at only $10/year — they’re also ad-free. (I hate ads).

But wait! There’s more! You can also install a “sticker” or widget on your website or blog. You can see the style I prefer at the top of this blog post; one that fits better in the sidebar appears at the bottom of the sidebar on every page.

What’s Next

Of course, all this is not enough for a true weather geek like me. The Weather Underground supports a PWS webcam.

I’ve had webcams on and off for years and would really like to have one here. After all, not only do I have an amazing view to share, but my view of the sky would clearly show weather conditions that would interest other weather geeks.

AmbientCamHD
There’s always something new to add to a system, isn’t there?

The one that I know will be compatible with the system is the AmbientCamHD Outdoor WiFi WeatherCam. It has a few features I think I could use to create time-lapses. I’ve added it to my Amazon wish list, but I suspect I’ll likely break down and just buy it for myself before Christmas.

Some things I just can’t resist.

A Hellish Week

Be careful what you wish for.

I’ll admit it: when I’m on contract to dry cherries, I hope for rain.

Yes, I’m in Washington state. But no, it doesn’t usually rain much here. I’m on the east side of the Cascade Mountains. That’s the dry, desert side.

In past years, rain has been light. I could count the number of days I had to fly on the fingers of one hand. Last year, I think I went to the second hand. We had one brutal day when I flew more than 6 hours last year, flying over one orchard after another until every single one under contract had been dried. But there isn’t usually much rain.

And although I do get paid to sit around and wait for the rain — which sometimes requires me to sit around my base all day watching radar — I also get paid to fly. It’s the combination of the two forms of revenue that make the season worthwhile.

So I hope for rain.

This week, however, I got more than I wanted. A lot more.

Day One

It started on Monday. I was still based in Quincy, so when the call came at 4:15 AM, it seemed to make sense for me to get started on the 50-acre orchard north of town. But radar showed activity in the Wenatchee area where I had other orchards under contract. I decided to call my other pilot, Mike, who was two spots down from me in the RV park. If I got called to Wenatchee, he’d have to do all the drying in Quincy.

Of course, I woke him up. But that’s part of the job. Our daily standby pay guarantees that we’ll be ready to fly from first light to last light. In Washington, in the summer, that’s a 17-hour day.

It was a good thing I called Mike because I’d been flying only 20 minutes when the call came to dry my first orchard in Malaga. Mike was enroute to the Quincy orchard when I left, telling him to start where I’d left off: at the first wind machine on the west end moving east.

I dried 26 acres in two orchards in Malaga and Wenatchee Heights. Then I returned to Quincy to dry 32 acres in two orchards there with a refueling in between. Then back to Malaga, Monitor, and Wenatchee Heights — multiple times — to dry a total of 177 acres in five orchards, one of which I dried four times.

It rained all day long, barely stopping long enough for us to get in and fly before the rain started up again.

I say “us” because I wasn’t the only helicopter flying. There was at least a dozen of us — R44s, JetRangers, Hughes/MD 500s, Hillers, and even a big, fat Huey. We were darting all over the place, making position calls on the informal air-to-air frequency, 123.45.

For the most part, pilots were polite and informative to avoid traffic conflicts, but there were exceptions. When one jackass flew 50 feet over the top of me while I was hovering at treetop level in an orchard in Malaga, I slammed him over the radio to make it clear that such behavior simply wouldn’t be tolerated. I don’t know whether he was being dumb or inconsiderate or simply trying to piss off the only female pilot drying cherries this year. But as anyone who knows me well can tell you, I don’t take bullshit from anyone. If I’d met him later in the day at the FBO, I probably would have attempted to break his nose — I was that pissed off.

I finished up long after sunset, when there was barely enough light to get back to my Quincy base. I’d spent 8.5 hours in the air, including all repositioning time. I’d dried a total of 245 acres of cherry trees.

What a day!

Back at my base, Mike’s wife had dinner on the table for me. Mike had spent a lot of the day flying, too, but not nearly as much as me. He’d already eaten but kept me company — and joined me to eat some of the ribs leftover from the day before — while I ate. I was exhausted when I went to bed.

But the forecast hinted that there would be more the next day.

Day 2

Although I really expected to be called out very early in the morning, I didn’t do my first dry until after 7 AM. The calls came in one after the other, evenly spaced apart. 7 acres in Malaga, 19 acres on Wenatchee Heights, 35 acres up Squilchuck Canyon, 35 acres in Monitor, 23 acres in Malaga, 7 acres in Malaga (again), and 35 acres in Monitor (again). Along the way, I refueled twice at Wenatchee Airport. I even had enough time to order, take delivery of, and eat a pizza.

In the meantime, a friend of mine in Quincy called to say that there was a bee swarm in a tree in her yard. She knew I wanted to catch it — that’s why she called me. But I was stuck in the Wenatchee area until there was no chance of rain there. I told her I’d come as soon as I could.

Storms over Wenatchee
For a while, I just sat up at my future home and watched the storms move through Wenatchee.

I got called out to do that 35 acres in Monitor again after lunch. When that was done, it wasn’t clear whether I’d have to do any more drying. I had plenty of fuel on board and I was sick of hanging out at the airport, so I flew up to that lot in Malaga that I plan to buy, landed, shut down, and spent about an hour sitting on the best view spot just watching the world around me. It was very restful.

After about 45 minutes, I figured I was done for the day so I started up again and headed back toward Quincy. I’d gotten as far as the Rock Island dam when my phone rang. It was a client. I made a big, sweeping turn at 110 knots and headed back to dry that 35 acres in Monitor (again).

By the time I was done, it was after 5 PM. Mike had called to let me know that we’d been invited to go out for dinner (and possibly drinks) with another pilot and his grower clients in Quincy. And I still had that bee swarm to catch. And I needed a shower. Desperately.

I headed back to Quincy.

By 7 PM, I’d caught the bee swarm, showered, and was sitting down with new friends in the Moose Lodge (really!) in Quincy WA.

It was 8:30 when a grower in East Wenatchee called me. He was not one of my clients, although I’d tried at least twice to sign him up. He preferred to hang around at the airport and make friends with the pilots so he could convince them to dry his trees off contract. That made it possible for him to avoid paying standby fees. He had apparently been successful doing this for several years.

But that evening, he was in dire straits. It had rained again in Wenatchee and his orchard was soaked. And he couldn’t find any pilot to come — they were all busy drying orchards under contract. (That’s why growers contract with us. Duh.) He seemed to think I might be flying in the area and could squeeze him in. I told him I was in Quincy and done for the night. He hinted that he might want to get on contract with me. I told him I was already at capacity for both of my ships. I told him that if he’d contacted me earlier, I might have been able to add another ship and pilot and cover him under contract. I told him it was too late to launch from Quincy anyway. (For the record, I would have launched right up until 8:45 for a client under contract; sunset was about 9 PM that night.)

When I hung up, I felt bad for him, but also kind of glad that he was being taught a valuable lesson. But I discovered that he found another pilot to dry for him after all — probably first thing in the morning. (Some of the pilots need to be taught a lesson, too.)

Total for the day: 196 acres, 5.7 hours of flight time.

Day 3

I was awake the next morning at 3:51 AM when I got a text from one of my clients telling me to dry all four of his orchards in the Wenatchee area. It had rained overnight and he needed them dry before the sun hit them.

Morning Dry
I used GPS track on my phone to show exactly where I flew on Wednesday morning. I started in Quincy, went to Monitor, then Malaga, then Wenatchee Height. Then I refueled at the airport, dried an orchard up Squilchuck Canyon, and returned direct to Quincy. 112 total miles.

I texted him back and told him I’d be at the first orchard at 4:45 AM. Of course, I was still in bed when I texted this. And the orchard was 30 nautical miles away — the farthest one. And it was still dark out.

I got up, made coffee in a travel mug, and pulled on my flight suit while Penny was out doing her business. Then I lifted Penny back into her bed, pulled the cover off Alex the Bird, grabbed my coffee, and headed out.

I preflighted with a flashlight and had the engine running by the time the horizon became clear. I took off and flew a semi-direct course. I was hovering over the first row of rainier cherry trees on the east side of the orchard at exactly 4:45. That simply amazed me.

Nice sunrise, too. A thin layer of stratus clouds kept the area shaded but glowed pink as the sun rose.

I was over the second orchard when I called Mike to let him know I was flying already. He flew later that morning in Quincy.

Maria and Penny
Cheryl snapped this photo of me in my flight suit with Penny shortly after my return from flying.

It was a quiet day — just the four orchards totaling 96 acres. I was done before 9 AM and after refueling, went back to Quincy. I spent the rest of the day packing my my RV in preparation for moving it to Wenatchee Heights for the rest of the season. Unfortunately, my next door neighbor had parked in such a way that I couldn’t hook up my pickup truck to the trailer. So I had to wait until 5:30 to leave. It was mostly sunny most of the day in Quincy and kind of hot and humid. I ran the air conditioning for a while.

At 6 PM, Mike, his wife Cheryl, and I headed to Wenatchee Heights. Mike was driving my truck and trailer. Cheryl was driving my Jeep towing my boat. (Mike and his replacement guy Ron are using the Jeep while they’re working for me.) And I flew up in the helicopter. I beat them there (of course) and was visited by neighbors I hadn’t seen since the previous season. Then they arrived and we parked the trailers. They drove off in the Jeep and I started settling in.

I left in the truck at 8 PM to go back to Quincy and pick up the things I’d left behind: my kayak, my Traeger grill, some nice wood palettes I’d been collecting, and my captured bee swarm, which had been flying around its temporary home all day. I’d gotten as far as Rock Island by 8:20 when my phone rang. Could I dry that orchard up on Wenatchee Heights?

If I’d been at my base — where technically, I should have been while on standby — the answer was yes. So even though I had to drive 20 minutes to get back to the helicopter and that would make it very late indeed, the answer was still yes. I turned around and drove, calling Mike along the way to let him know I wouldn’t make it there that night.

At 9 PM, right around sunset, I was hovering over the last 19 acres I’d dry that day. I was on the ground at my new base, only 2-1/2 miles away, by 9:30 PM.

Total for the day: only 115 acres in 3.6 hours, at least 1 hour of which was (non-billable) repositioning time.

Day 4

By Wednesday night, I thought the drying flights were over. There was a very slight chance of rain the next day — only 20% — when I went to bed. After years of watching weather here, I can tell you that 20% is barely worth thinking about.

So imagine my surprise when I got a call at 4:54 AM from a grower telling me that it was raining in Monitor and he’d likely need me when it stopped.

I got out of bed, made my coffee, took care of my critters, and suited up. The call to dry came at 5:45 AM from a different grower in Malaga. And that’s when the fun began.

Orchard in the Clouds
For a while, the orchard I was waiting to dry had a cloud sitting right on it.

For the next few hours, I dried six different orchards — two of them twice — stopping only to wait out another rain storm and to refuel. It got intense for a while: while I was drying the third orchard, I had my next two orchards lined up and waiting for me. But everyone stayed calm, including me, and it got done timely. Indeed, after finishing all my orchards at around 11:30 AM, I saw other pilots heading out to start drying other ones near mine.


I waited at my base in Wenatchee Heights for rainstorm to pass through the area. This nosecam video clip shows my minute-long “commute” from my base to the orchard I dried across Squilchuck Canyon. There were lots of low clouds that morning.

Total 162 acres in 4 hours of flight time.

I was finally able to retrieve my possessions (including bees) in Quincy that evening.

Enough Already!

You know what they say: be careful what you wish for. This past week was a real lesson in that.

All cherry drying pilots want it to rain. Rain = money. But how many of us want it to rain this much?

I certainly don’t.

There comes a point where there’s so much rain that helicopters simply can’t keep the cherries dry enough to prevent splitting. I’ve heard loss numbers ranging from 10% to 50% in orchards that do have helicopters on contract. (This is better than another grower I’m in touch with who doesn’t use helicopters and had 60% splits; he’s not picking at all.) I’d also heard that loss rates were so bad in Mattawa (south of me) that growers gave up and stopped calling helicopters to dry. That doesn’t do us any good at all.

And while it’s nice to be able to send out invoices, I admit that I felt bad for my clients when I sent out the ones for this week. When you have a 35 acre orchard that needs to be dried multiple times in a day multiple times in a week, the costs climb quickly. Yes, that’s revenue for me. But it’s also a huge cost for the grower. While my services will make the difference between a crop that can be picked and sold and one that’ll rot on the trees, it must be painful for them to face such large bills.

But most of all was the sheer exhaustion I felt after hours of hovering at treetop level over fruit trees — especially the ones in orchards planted in steep terrain with numerous obstacles to avoid. It’s tedious, dangerous work. Three helicopters were lost so far this season: a JetRanger went down in bird netting near Royal City, a 500 had a wire strike that took it down, and an R44 had a wire strike that I’m still waiting to learn more about.

I can’t argue the profitability of a rain-filled week. I dried a total of 718 acres of cherry trees with 21.8 hours of flight time. I billed accordingly.

And I still have 6 weeks left in my cherry drying season.

Hail
This hail fell in Prosser, WA this morning. So glad it didn’t fall anywhere near my helicopter.

Right now, it’s cloudy outside, with thunderstorms rolling through the area. Ron dried an orchard in Quincy 1-1/2 times. (It started raining when he was half finished so he waited it out and restarted.) I’ve been watching severe storms moving northeast through the area mostly east of me. A severe storm passed over Lake Chelan at Manson near where my friend Jim is based with his helicopter. One of my growers sent me a photo of hail the size of…well, the size of cherries… that fell in the Prosser area. Hail like this can destroy a helicopter, so I’ll be covering mine up in case any storms like that pass through here.

Will I fly today? Who knows? In all honesty, I hope I don’t.

I’d like a rest — and I’m sure my clients would, too.

Postscript, 30-June-2013

Two things I’d like to mention.


Nick Henderson put this video of his cherry drying work on YouTube. Check it out.

First, I wound up flying another 5 hours on Saturday, drying a total of 208 acres. The rain came down fast and furious, with thunderstorms rolling through and flash flood warnings for Wenatchee. More than an inch of rain fell near where I’m based.

Second, fellow cherry drying pilot Nick Henderson put together this little video of his cherry drying work this week if you want to see what it looks like from the pilot’s point of view.

Today (Sunday) is a beautiful clear day — perfect for a well-deserved day off!

Why My Mind is [Always] on the Weather

I’m a walking, talking, texting weather resource.

Yesterday was a beautiful, clear day in central Washington, with the occasional little puffy cloud floating across the bright blue sky. It was warm in the sun, cool in the shade, and a gentle breeze kept any insects from becoming a nuisance.

A perfect day to visit with a friend down in Mattawa, a 40-minute drive south.

I was about halfway there when my phone rang. It was one of my cherry drying clients. I pulled over to make sure I didn’t lose the connection on the winding river-side road. After exchanging greetings, she asked, “So what’s the weather forecast?”

“Twenty percent chance of rain tonight and twenty percent tomorrow.”

We finished the conversation, both promising to keep an eye on the weather. I hung up and continued on my way.

You might be wondering why I knew, off the top of my head, the weather forecast for the next 24 hours. Simple: It’s part of my summer job.

My job depends on the weather. If it’s a nice day, I get the day to myself and can wander away from my base. The nicer the day, the farther I can wander. If it’s a rainy day, though, I have to hang around, waiting for a call to fly.

This means I need to know the upcoming weather all the time.

How I Track the Weather

I use five different resources to track the weather.

  • Seven-Day WeatherThe National Weather Service at weather.gov offers a 7-day forecast with “at-a-glance” graphics and a detailed textual summary. I can also click a link to get an hourly weather graph that charts percent chance of rain, percent of sky cover, temperature, humidity, wind, etc. hour-by-hour several days into the future. This is my primary source of weather forecasting information.
  • Current RadarWhen rain is in the area or on the way, I use the radar graphic at the Weather Channel to see where the rain is and which way it’s going. What I like about this particular radar graphic is that you can drag and resize the map to change the view. I can see the big picture to get an idea of how much rain is on its way and zoom in to see exactly where it’s falling. This is my primary source of current weather information when I’m in front of my computer.
  • WeatherBug on iPadWhen I’m out and about and have access to the Internet, I use WeatherBug on my iPad to see weather information, including a radar graphic, forecast summary, and hour-by-hour forecast. I can also use its Webcam images to help judge visibility in the event that I need to cross the Cascades to get to Seattle. (Which I don’t usually do during the season.) WeatherBug is also available for mobile phones; I really do need to get it back on my BlackBerry.
  • In the RV, I use my radio scanner to listen to weather summary and forecast information from the National Weather Service for my area. It’s basically local weather radio. It isn’t nearly as helpful as the other sources, but it does offer a good overview for my area and playing it tends to keep Alex the Bird quiet.
  • I also look out the window a lot. Knowing which direction the weather usually comes from and watching the sky out that way can give me an early heads-up. This is especially useful when I’m out running errands and don’t have access to any of my other sources.

What’s amazing about the weather forecast is that it’s only accurate for a short while. Yesterday, the chance of rain this morning was 20%. When I got back from my day out, it was 30%. This morning, it was 50%. And then it started raining. It’s been raining for at least an hour and radar shows me that we could get at least an hour more of the stuff.

Knowing this can keep me out of trouble. 20% didn’t seem like much of a chance — and it isn’t. But 50% is a pretty good chance of rain. It went from 20% to 50% in less than 12 hours. So I have to constantly be checking my sources.

Today’s Weather Story

This morning, my client’s son, who manages the orchard, called. It was 7:46 AM. “What’s the weather?” he asked.

I told him what I saw on radar: a long line of rain showers stretching all the way from southwest of Portland to us, moving our way. “It’s raining here,” I added.

His orchard is 6 miles northwest of my position. He lives another 20 miles north.

“I’m on my way to the orchard,” he told me. “I’ll call you when it stops.”

He means that he’d call me to fly when it stops.

So I’m sitting here, dressed in my flight suit and ready to go. The rain is still pattering against the roof and windows of my RV. The radar shows some heavier rain inbound from the Ellensburg area. And more rain beyond it that, if we’re lucky, will pass to the south of us. (That’ll make my buddy Jim happy. He’s down in Mattawa, doing the same thing I am. In fact, we spend far too much time texting each other about the weather.)

Waiting to FlyThe helicopter is a quarter mile away and already fueled and preflighted. All I have to do is pull off the blade covers. I can be airborne within 10 minutes of my client’s call. The orchard is a 4-minute flight from here. So I’d much rather sit in my nice warm RV, watching the weather on radar, than sitting out in my truck by the helicopter, blind without most of my weather sources.

But I guess this explains why my mind is always on the weather — at least this time of year.
