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 […]
