Tomer’s Take: The next storm system hits UT, WY, and CO between 11/18-11/20. Heavy snow appears likely for the Wasatch. Another storm system races through with even colder air 11/23-11/24. My forecast video: Current Setup Water vapor satellite shows the slow moving deep trough moving into CA directing atmospheric traffic. But, also notice the Polar […]

Snow forecast through Thanksgiving
Tomer’s Take: Three different storm systems are lined-up through Thanksgiving. My forecast totals have increased for the Wasatch. The third storm system 11/23-11/24 is trending slightly stronger. 2 inches of new snow (so far) is being reported at Alta, UT. Snow is also moving into Colorado’s Central and Northern Mountains. It just started snowing at […]
Three storm systems through 11/24
Tomer’s Take: A large trough of low pressure approaching CA dictates the flow of business across the West through 11/20. Two cold fronts mesh with energy from this trough generating snow for ID, WY, UT, MT, CO, NM. A third storm system tracks across the PNW, ID, MT, UT, WY, CO 11/23-11/24. My forecast video: […]
Active storm track through 11/20
Tomer’s Take: I’m tracking a large CA trough of low pressure and two cold fronts coming out of the PNW. The interaction should generate snow for PNW, BC, Banff, MT, ID, WY, UT, CO, and NM. My forecast video: Current Setup Water vapor satellite shows the large CA trough. It really dictates the near future. […]
Three storm systems through 11/22
Tomer’s Take: I’m forecasting three different storm systems through 11/22. Heavy snow appears likely. The first low originates in CA (where totals will be low) and tracks through UT, AZ, NM, and CO. This first trough greases the skids. The 2nd low races from the PNW through ID, MT, WY, UT, and CO to fill […]
Snow forecast next 9 days
Tomer’s Take: What once looked like a significant snow event for CA has changed. Why? Weak atmospheric river (AR) contribution and poor trough trajectory. Looking down the road, this initial trough will grease the skids for two additional areas of low pressure originating in the PNW that look more robust for the PNW, BC, ID, […]
Heavy snow for BC/PNW; Western pattern shift update
Tomer’s Take: Snowfall continues to trend down for CA and the Interior Rockies 11/13-11/18. Trough trajectory and weak atmospheric river (AR) intensity are two limiting factors. A larger trough of low pressure across the West might be possible after 11/18. That said, heavy snow is likely for BC and higher elevations of the PNW with […]
Pattern Shift Trending Weaker for CA & Interior Rockies
Tomer’s Take: The next pattern shift continues to trend weaker on/after 11/13-11/18 for CA and the Interior Rockies. The main beneficiaries of heavy snow are ski areas in the PNW/BC. Optimism three to four days ago for heavy snow was predicated on a moderate to strong intensity atmospheric river (AR) contribution. That does not appear […]
Snow for CO then big pattern shift
Tomer’s Take: Light to moderate snow is likely across Colorado’s mountains on 11/8-11/9 along with colder air. Then the Western pattern shifts with a large trough diving south from PNW/BC into CA on/after 11/13. The overall snowfall trend is down versus yesterday with less atmospheric river contribution. 7 inches of new snow in the last […]
Snow for UT, CO then big pattern shift for the West with big totals possible
Tomer’s Take: Snow is falling across the Wasatch today then Colorado gets light to moderate accumulation 11/8-11/9. A much more significant pattern shift occurs on/after 11/13. A deep trough starts in the PNW/BC then digs south through CA with impressive snow totals and colder air. An atmospheric river (AR) component is also possible along with […]
