First big mountain snow of the season

Tomer’s Take: The first significant mountain snow of the season is possible 10/22-10/24. Beneficiaries: PNW, Banff, MT, ID, UT, WY, CO. Air temps will run 10-20 degrees below normal. The jet stream delivers strong wind (40-80mph) to the higher peaks of UT, WY, MT and CO between 10/22-10/24. I’ll drill-down on this in future updates […]

When will it snow, part 2

Tomer’s Take: Pattern change remains possible on/after 10/23 across the West. Beneficiaries: CO, UT, WY, ID, MT, PNW, Banff. Lower atmospheric pressures replace high pressure ridge. Snow and colder temps = net result. If this verifies it would be the first significant snowfall of the season for much of the Intermountain West. Current Setup Infrared […]

When will it snow?

Tomer’s Take: A large Western ridge of high pressure remains in control through 10/22. A pattern change is possible on/after 10/23. A large dip in the jet stream and lower atmospheric pressures might replace the large Western high pressure ridge. This pattern change might run 10/23-10/27. Net result: snow and colder temps for UT, CO, […]

Winter forecast 2022-2023

Tomer’s Take: Rare triple-dip La Nina. Multivariate ENSO Index strongest since 2010. Warm blob is back but for how long? Abnormally warm and dry Fall season across the West. Late start to Winter. Large Western ridge of high pressure September 2022 – March 2023. Overall, target PNW, British Columbia, Banff Area, Wyoming, Idaho, and Montana […]

Tropical remnants 9/13-9/17

Tomer’s Take: Mega High breaks down 9/9. Wildfire smoke circulating. Tropical remnants fill the void 9/13-9/17. Light mountain snow possible. Run Rabbit Run forecast below. Current Setup You can see where the tropical remnants will come from in on this water vapor satellite image. Wildfire Smoke Smoke is circulating from wildfires in ID, OR, and […]

Mega High then tropical remnants

Tomer’s Take: All-time temperature records continue to fall. Mega high pressure dome running 3 standard deviations above 20-year average. Core of the heat is CA, NV, UT. High breaks down on 9/9. A small high pressure dome re-builds 9/11-9/12. Tropical remnants could affect the West on/after 9/12 through 9/17. After this Mega High breaks down […]

Mountain weather update 11/7: The week ahead

There are two storm systems lined-up for the West. The first storm is minor. The 2nd storm system is the one to watch for CA, UT, WY, and CO. The first storm system is already moving across the intermountain west with minor amounts of rain/snow depending on elevation. The 2nd storm system sitting over the […]

Storm system crossing UT, CO, WY; Small atmospheric river early next week

Light to moderate snow is falling in the mountains of Utah, Wyoming, and Colorado. I’m forecasting minor snow amounts except for a couple isolated locations in Colorado’s Northern Mountains like Cameron Pass. I’m forecasting a few inches of accumulation in Utah’s Wasatch and Wyoming’s Teton Range. In Colorado, light to moderate accumulation is likely in […]

Mountain Weather update 10/31

There are a few storm systems lined-up into the Pacific Ocean targeting the first week of November. Each will follow a similar storm track into the PNW then into the intermountain West. Each front delivers light to moderate snow amounts to the WY, CO, MT, and UT. Unfortunately, the storm track does not favor California. […]

Mountain Weather update 10/28

The next storm system is moving into the Pacific Northwest. It then hits the Intermountain West between Saturday and Monday. It appears minor for most ski areas. There is a second storm storm system behind the first one. It moves into California on November 1 and then spreads snow into the interior Rockies thereafter. It […]
