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 […]

Tomer’s Take: Feet of snow accumulation continues in CA with a moderate to strong intensity atmospheric river (AR) surge through 1/10. The next surge occurs 1/14-1/17. Snow from both AR’s hit UT, WY, ID, CO. My afternoon mountain weather update video with new numbers: Mammoth Mountain is reporting 31-46 inches of new snow. Additional snow […]

Tomer’s Take: The atmospheric river (AR) continues through 1/16 then fades. The next two AR surges deliver feet of snow to the West. Heavy snow continues in the Sierra through 1/10 with a moderate to strong AR surge. Snow levels run abnormally high on 1/9 then gradually fall. Mammoth Mountain is reporting 14-18 inches of […]

Tomer’s Take: The atmospheric river (AR) runs through 1/16 then fades to zero. I’m forecasting big snow totals in CA, PNW, BC, parts of ID, parts of MT, WY, UT, and the Western Slope of CO. My forecast video 1/8: Current Setup Water vapor satellite shows the Pineapple Express flow and remaining areas of low […]

Tomer’s Take: I’m forecasting 3-4 additional atmospheric river (AR) surges through 1/16. Sierra snow levels will run abnormally high with the biggest accumulation above 7,000ft. My forecast video 1/7: Current Setup Water vapor satellite shows the Pineapple Express and low pressure systems lined-up through 1/16. Forecast Pattern Forecast jet stream valid 1/9. This is a […]

Tomer’s Take: I’m forecasting three more atmospheric river (AR) surges through 1/15. Beyond 1/15 the atmospheric river is much weaker and fading. Snow levels will run high 1/7-1/10. Best Sierra snow stays above 7,000ft. Alta, UT is reporting 11″ in the last 24 hours. The pushes them up to 319″ for the season. Current Setup […]

Tomer’s Take: A monster storm system loaded with atmospheric river (AR) continues today in CA, WA, OR with 100mph wind and high snow levels. Part of that moisture then moves into the interior Rockies including NV, UT, ID, WY, and CO. There are three additional weak to moderate intensity AR surges through 1/14. My afternoon […]

Tomer’s Take: I’m forecasting four moderate atmospheric river surges through 1/13. Primary beneficiaries are CA, OR, WA, BC. Snow is also likely through the interior Rockies. My forecast video 1/4: Current Setup Visible satellite shows a monster area of low pressure hitting the West Coast with a firehose of moisture. Notice how well-defined the area […]

Tomer’s Take: I’m tracking three moderate intensity atmospheric river (AR) surges through 1/12. Biggest totals occur in CA, WA, OR, BC. Current Setup Infrared satellite shows the Pineapple Express and low pressure systems lined-up. Forecast Pattern Forecast jet stream valid 1/12 shows a choppy jet stream with well-defined dips and ridges. This pattern favors the […]

Tomer’s Take: The atmospheric river (AR) continues through 1/11 with the biggest impacts in CA, WA, OR. A moderate intensity AR surge occurs in CA 1/4-1/5. This storm impacts UT, WY, ID, CO on 1/5-1/6. There appears to be another moderate intensity AR surge for CA/West Coast on/around 1/10. 7-Day Totals: Brighton, UT is reporting […]
