*Updated 2pm 11/30. Forecast is on track, no big changes.Tomer’s Take: A golden combination of jet power, stacked WNW Flow, and moderate to strong intensity atmospheric river (AR) contribution delivers 1-3 feet of accumulation in parts of the PNW, BC, ID, WY, UT, and CO. My forecast numbers for CO are back up – I […]

Big totals likely with powerful WNW Flow pattern in PNW, BC, ID, WY, UT, CO
Tomer’s Take: Both jet streams become active and deliver moisture 11/30-12/5. Plus, the northern branch appears to setup a WNW Flow pattern with big snow accumulation in PNW, BC, ID, WY, UT, and CO. The rich flow in the PNW is associated with a moderate to strong intensity atmospheric river (AR). My Afternoon forecast video […]
Active Western flow 11/30-12/7 with heavy snow potential
Tomer’s Take: Both jets turn active 11/30-12/7 with heavy snow likely in the PNW, BC, ID, WY, UT, CO. In the Northeast, heavy snow accumulation is possible with a coastal storm system 12/3-12/4. My forecast video: Crystal clear view of Cody Bowl at Jackson Hole. Next snow arrives late 11/30-12/4. Current Setup Water vapor satellite […]
Western pattern turns active 11/30-12/6
Tomer’s Take: A brief ridge of high pressure dominates through 11/29 then it starts to break down. An active pattern takes shape 11/30-12/6 with both jets contributing. My video Forecast: 7 inches in 24 hours reported at Killington, VT: It’s a clear morning at Loveland Ski Area. 12,000ft air temps are around zero. Next snow […]
Snow forecast next 9 days
Tomer’s Take: The higher elevations of the Northeast get moderate to heavy snowfall late 11/26 into 11/27 (with rain at lower elevations). Snow levels start high around 2k-3k then drop with bulk of snow in northern VT, NH, ME. Out West, high pressure takes over through 11/29 then the pattern shifts with both jet streams […]
Weekend Primer & What’s Next through 12/5
Tomer’s Take: Snow is moving out of UT & WY and into CO & NM with snow accumulation through 11/25. Then, the pattern shifts with high pressure ridging 11/26-11/29. The jet resets 11/30-12/5 with a stormier pattern and potential moisture loading on both jets. My forecast video: Forecast Radar & Satellite Forecast Totals Bulk of […]
Thanksgiving Update: Snow through 12/2
Tomer’s Take: A Canadian cold front is diving south through WY into UT, CO and NM 11/23-11/25. Forecast snow totals are down slightly (-15%), but snow ratios remain high with much colder air. Then it’s a drier stretch with high pressure ridging 11/26-11/30. Pattern might turn stormier after 12/1 as jet resets. My forecast video: […]
Snow forecast through end of November
Tomer’s Take: The next western storm system hits 11/22-11/25 in MT, UT, WY, CO, and NM. It delivers much colder air and higher snow ratios. Then, the pattern shifts with a much drier stretch through 11/30 and high pressure ridging. Stormier pattern might develop on/after 12/1 as jet stream resets. Snow continues today across the […]
Snow hits MT, WY, UT, CO, NM 11/23-11/25
Tomer’s Take: A Canadian cold front races south through MT, WY, UT, CO, and NM between 11/23-11/25. The flow shifts after 11/25 and turns much drier through 11/30. Clear as a bell this morning at Alta, UT. Snow arrives around 5pm on 11/23. Crystal clear at Loveland Ski Area. Snow arrives around 5pm on 11/24. […]
Next storm system 11/23-11/25 with snow for MT, WY, UT, CO, NM
Tomer’s Take: Off/on light snow continues today in CO. This storm system then races into the Northeast and delivers moderate to heavy snow accumulation at the ski areas of VT, NH, and ME between PM 11/21-11/22. What’s next? A strong Canadian cold front dives south through MT, WY, UT, CO, and NM with much colder […]
