Tomer’s Take: The jet stream shifts north favoring the Northern Rockies early in the period. I’m still forecasting a fast NW Flow, but it’s trending much weaker. I’ve reduced most forecast snow totals. Then the pattern shifts south with lower atmospheric pressures across the West by the end of January. My forecast video 1/22: Forecast […]

Fast NW Flow West with Big Totals
Tomer’s Take: The Western pattern is changing with the jet moving into a Northwest Flow (NWF) type orientation. Big snow totals are likely through 1/30 in certain preferred NWF locations. Wolf Creek is reporting 10 inches in the last 24 hours. That’s now 66″ in the last 7 days. My forecast video 1/21: Current Setup […]
Fast NW Flow for the West; 2-3 storm systems NE
Tomer’s Take: One last southern track low is sliding through the Four Corners. Then the jet stream moves north into a NW orientation. A fast NW flow sets up with several fast moving cold fronts/low pressures diving south out of Canada into MT, WY, UT, CO. In Northeast, 2-3 storm systems through 1/29 with 1-3 […]
Western Pattern Shift; 2-3 Storm Systems Northeast
Tomer’s Take: A Western pattern shift is underway as the jet gradually moves north and takes on a NW oriented flow. A deeper trough sets up in the Northeast with 2-3 different storm systems lined-up through 1/28. My forecast video 1/19: Current Setup Water vapor satellite shows a shifting storm track out West. Storm systems […]
Snow forecast through end of January
Tomer’s Take: A panhandle hooker storm system continues to slide through CO/NM then it becomes a Northeast storm system. The Western pattern then shifts. The jet moves north and higher pressures build across the Pacific and West Coast. Two additional storm systems might deliver big totals to the Northeast on 1/22-1/23 and 1/24-1/25. Wolf Creek, […]
Pattern through February 1
Tomer’s Take: A major low pressure (last of the atmospheric river) slides through UT/AZ/CO/NM next 24 hours with big totals. Then, the pattern shifts north with high pressure ridging over the Pacific Ocean and West Coast. The jet takes a NW orientation favoring PNW/BC/ID/MT/UT/WY/CO. By February 1, a trough might establish itself across the entire […]
Final AR storm system then new pattern emerges
Tomer’s Take: The final storm system loaded with atmospheric river (AR) moisture is moving through CA. It’s a southern track low headed for AZ, NM, UT, and CO with moderate to heavy snow accumulation. What happens after this? Higher atmospheric pressures build across the Pacific/West Coast pushing the jet stream north where it favors the […]
Pattern through late January
Tomer’s Take: The final atmospheric river (AR) surge is underway with big totals across the West. What happens after? A transition occurs with a high pressure ridge building. My forecast video 1/13: Current Setup Infrared satellite shows the Pineapple Express and remaining two areas of low pressure. Forecast Pattern Forecast jet stream valid 1/22. Notice […]
One more AR surge then new pattern emerges
Tomer’s Take: One more large atmospheric river (AR) surge occurs through 1/17 then the pattern shifts through late January with high pressure ridging. My forecast video 1/12: Mammoth Mountain is crystal clear this morning after about 7.5 feet of snow in the last few days. I’m forecasting another 2-3 feet with the next AR surge. […]
The final AR surge; Late January Outlook
Tomer’s Take: 1-2 additional atmospheric river surges are likely through 1/17 then it fades. A high pressure ridge is possible across the West on/after 1/22, but some places might actually be favored for snowfall. Snowbird, UT is reporting 36 inches in 48 hours. Mammoth Mountain, CA is reporting 72 inches in 72 hours. My afternoon […]
