New Year’s Atmospheric River through 1/9 with a twist

Tomer’s Take: The atmospheric river (AR) continues through 1/9, but the storm systems weaken 1/3-1/9 once they move into UT, CO, NM. Snow levels remain elevated in the Sierra because of this warm, moist AR. They’re also elevated on 12/31 in the Wasatch with rain reported at the base of Park City. Snow levels should […]

Snow forecast through 1/8

Tomer’s Take: The atmospheric river now looks to continue through 1/8. Feet of additional snow accumulation likely in CA, UT, WY, CO. But, the 2nd period appears to generate less snow for UT than previous updates. My forecast video 12/30: Current Setup Infrared satellite shows the Pineapple Express and parade of low pressure systems lined-up […]

Atmospheric River through 1/7

Tomer’s Take: The atmospheric river continues through 1/7. The next surge 12/30-1/1 is ‘moderate to strong’ intensity. Feet of grand total snow. My forecast video 12/29: Current Setup Infrared satellite shows the Pineapple Express and parade of storm systems lined-up through 1/7. Forecast Pattern Forecast jet stream valid 1/6 shows the west to east jet […]

Atmospheric River through 1/6

Tomer’s Take: It now looks like the atmospheric river (AR) continues through 1/6 generating feet of grand total snow across the West. Awesome sunrise view at Palisades Tahoe this morning in-between storm systems. The first storm system delivered 13-22 inches of snow at higher elevations with a rain/snow problem lower. My forecast video 12/28: Current […]

Feet of accumulation through January 4

Tomer’s Take: A powerful atmospheric river remains on track for the West through 1/4. Grand totals of 1-5 feet (or more) for PNW, BC, CA, UT, WY, and CO. -> See below for my forecast grand totals and snow timeline for the Wasatch. My forecast video 12/27: Current Setup Infrared satellite shows the storm track […]

Big totals with a powerful 9-day Atmospheric River

Tomer’s Take: Data continues to suggest a “strong to extreme” intensity atmospheric river (AR) 12/27-1/4 for most of the West. Grand totals (see below) of 1-5 feet or more. My forecast video 12/26: Current Setup Water vapor satellite shows the organizing atmospheric river reaching all the way into the western Pacific. This is the Pineapple […]

Big totals ahead; Snow forecast through 1/3

Tomer’s Take: A major atmospheric river (AR) pattern hits the West with big snow totals 12/27-1/3 with 4-5 distinct waves of moisture. A larger storm system hits the Northeast on 1/1 but it appears to be mainly rain. My forecast video 12/25: Current Setup Infrared satellite shows the organizing atmospheric river over the Pacific. Areas […]

Snow forecast through 1/1; Strong atmospheric river

Tomer’s Take: A ‘strong to extreme intensity’ atmospheric river arrives on/after 12/27 through 1/3 across the West with big snow totals. Out East, it’s cold and windy in the wake of the Blizzard with lake effect snow. I snapped this aerial photo of the Eastern Plains of Colorado on Friday 12/23. It looks like the […]

Atmospheric River ushers in 2023

Tomer’s Take: Looking ahead, a moderate to strong intensity atmospheric river hits the West Coast on/after 12/27 through 1/1 with 3-4 different waves of rich Pacific moisture. Big totals likely. Big low in the Northeast continues: Strong wind, snow, rain, then back to snow for VT, NH, and ME. For example, Killington is reporting strong […]

Snow through New Year’s Eve

Tomer’s Take: The Western Arctic front races east and develops into a deep area of low pressure over the Great Lakes. It flushes the ski areas of VT, NH, and ME with warm air and mixed precipitation. Out West, Arctic air lingers with a moderate to strong intensity atmospheric river (AR) on/after 12/27. My forecast […]
