Tomer’s Take: Active northern jet branch has three additional storm systems lined-up for parts of the West. As mentioned yesterday, Alta, UT could reach 900″. Jackson Hole, WY should easily reach 600″ for the season. High pressure might build for May 1. My forecast video 4/16: Forecast Freezing Level Wasatch, Maximum Height: 4/16: 11300′ 4/17: […]

Alta, UT might hit 900″; Three more storm systems lined-up through 4/24
Tomer’s Take: The pattern is NOT done with the West. I’m forecasting three additional storm systems through 4/24 and about 20 inches of grand total snow at Alta, UT. My forecast video 4/15: Aspen Highlands, CO Aspenweather.net has a great App run by Ryan Boudreau and meteorologist Cory Gates. They’re reporting almost 450 inches of […]
Late April/Early May high pressure ridge?
Tomer’s Take: Pattern stays active with new snow for PNW/BC/MT/ID/WY/UT/CO/NOCA through 4/21, an additional storm system on/around 4/24, then pattern might transition to a ridge of high pressure late April into early May. My forecast video 4/14: Current Setup Water vapor satellite shows the primary storm track from the Pacific into the PNW. Forecast Freezing […]
Pattern through end of April
Tomer’s Take: Freezing levels fall today (4/13) through 4/15 then start rising again with warmer air. Storm track favors PNW/BC/Northern Tier through 4/24 then uncertainty. One more photo of the dirty snowpack in Colorado…it’s a good one from Nick Green while skiing in Aspen, CO. Thanks Nick! My blog post yesterday explains this phenomena. Forecast […]
Dirty snow, late April pattern, and snow forecast through 4/21
A high wind event 4/3-4/4 deposited desert dust on Colorado’s snowpack. This seems to occur now every Spring. Dirty snow accelerates the melting of the snowpack by lowering albedo. I co-authored a peer-reviewed article on Colorado’s Dirty Snowpack in 2010. Below, MODIS visible satellite shows the brown tint to the snowpack in some places. Dust […]
Pattern through 4/20
Tomer’s Take: The storm track favors the PNW/BC/Northern Tier. One storm system drags a cold front with snow through UT, WY, CO, MT 4/12-4/14. Pattern shifts back to the PNW/BC through 4/20. March 2023 Pattern Looking back, March 2023 was a giant for Utah with record precipitation (dark green). In Colorado, the trend is clear. […]
Warm surge then snow through 4/19
Tomer’s Take: Avalanche warnings are in effect for the Wasatch Front. Freezing levels rise rapidly next 48 hours. The storm track favors the PNW/BC/Northern Tier through 4/12. This storm systems breaks loose on/after 4/13 and runs through UT, WY, CO. Forecast Freezing Levels Wasatch: 4/10: 13300′ <–24/7 above freezing 4/11: 13100′ <– 24/7 above freezing […]
Freezing levels surge then new snow through 4/18
Tomer’s Take: Freezing levels will rise rapidly 4/9-4/12 with widespread 50-degree high temps at 10,000 feet for CA, UT, and CO. My forecast video 4/9: Forecast Freezing Level Wasatch: 4/9: 12000′ 4/10: 13300′ <–24/7 above freezing 4/11: 13100′ <–24/7 above freezing 4/12: 12100′ 4/13: 6600′ CO Central Mountain Zone: 4/9: 11500′ 4/10: 14000′ 4/11: 14400′ […]
Wasatch Freezing Levels rising rapidly; Avalanche risk
Tomer’s Take: All-time record snowfall in Little and Big Cottonwood Canyons of 800″+ has setup both canyons with avalanche-rich conditions. These slides are running all the way to HWY210 and the valley floor. Now, air temps will warm quickly with maximum freezing levels far exceeding even the highest peaks in the Wasatch Range. Forecast Freezing […]
Western pattern shift; Spring skiing
Tomer’s Take: The Western storm track continues shifting north favoring the PNW/BC/Northern Tier. The longer range jet stream is low velocity with high pressure ridging. Spring skiing inbound. My forecast video 4/8: Current Setup Water vapor satellite shows an area of low pressure hitting the PNW/BC/Northern Tier. This is the dominate flow. Forecast Pattern Forecast […]
