SE5:EP5 - Evan Thayer: Bringing Us Utah Powder

It’s early season at Alta. OpenSnow forecaster Evan Thayer has left his meteorological screens in the hotel and is bashing his way down some fresh powder under the Collins chair. Life is good. If there is anyone we tens of thousands of Utah skiers owe a ‘thank you’ to, it would be Thayer, a weather nerd who hadn’t really planned his career path this way, but is thankful his former powder alert email list has turned into life as Utah’s snow forecaster.

The tools we have today to forecast weather are quite remarkable. The data availability and the scientific knowledge to analyze it are stunning. And that’s what Thayer does every morning, beginning at 4:00 a.m., crunching numbers, studying maps and putting out a meaningful forecast by the time we’re packing the SUV with skis at 7:00 a.m.

Thayer is making his third appearance on Last Chair here in season 5. He was the episode 3 guest in the debut season of the podcast back in December 2019.

In this episode, Thayer dives back into his past, growing up with a passion for weather going to CU-Boulder to study and ski, and finding his way to the Greatest Snow on Earth here in Utah.

It’s an insightful episode that explores his past and the popular weather app OpenSnow.

Well, Evan, how was your birthday at Alta?

Every early season I like to do a little staycation in Little Cottonwood Canyon. So I had a little birthday staycation at Gold Miner's Daughter. I knew there was a big storm coming. I knew I could get a room for a reasonable rate. And rather than deal with getting up early and getting up the canyon, it's kind of nice to wake up to fresh snow up there in Little Cottonwood Canyon, roll out of bed, get some breakfast, and just trundle out to the lifts.

Were you a weather nerd as a kid?

I was always a weather nerd. I was the kid who, back in the days prior to having internet, would set a cooking timer so I could run inside from playing with my friends and see the local on the eights on the old Weather Channel because that's when you could see the local radar.

You were in the early group of forecasters when OpenSnow was formed. How has it evolved?

It's grown a lot. It started as mostly three regions, and now we have, I don't know, 15 to 20 forecasters around the world writing daily snow forecasts. We've grown the product itself to have all sorts of different maps and overlays and different features you can use. Last year we launched Forecast Anywhere, which was a huge undertaking, but it allows a user to click on any point in the world and get the same quality forecast that you would get for, say, Park City or Alta. For any point in the world. You can see an hour-by-hour forecast for the next ten days.

How has that expanded the usage?

We have evolved as an app where I think traditionally it was all about powder – it was all about skiing. And if you ask me what I care about, what's the most important to me? I'll still say powder and skiing. But people are using the app now for all sorts of different things in the summer. They're using it for their hiking trips. We have trail estimated trail conditions that tell them whether it's a muddy trail, a snowpacked trail, or a dry trail. So if you're planning biking trips, hiking trips or backpacking trips, you can use it for that. We have smoke overlays. So in wildfire season, and how that's going to affect the air quality. We are working to forecast that to make sure you have, again, all the information you need to get out and enjoy nature.

OK, what about the whale?

That's a great question. The whale is unknowable. All I know is that they installed that on April 1st, 2022, after that moment, it started snowing and it felt like it never stopped. So
