Tomer’s Take: 3-4 storm systems are lined-up for the West through 4/28. Brief high pressure may develop April 28-May 1. Will Alta, UT hit 900″ by May 1? Yes, it appears likely. Will Aspen Highlands, CO hit 450″ by May 1? 50/50 odds. Will Jackson Hole, WY hit 600″ by May 1? Yes, it appears […]
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: […]
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 […]
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 […]
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 […]
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 […]
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. […]
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 […]
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′ […]
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 […]
