Tomer’s Take: 2023 features a continuation of the atmospheric river through 1/9. A moderate level intensity moisture surge occurs on 1/4-1/5 in CA, OR, WA. The jet becomes choppy through UT, WY, and CO on/after 1/4 with some ridge stress cutting down on snow totals. My forecast video 1/1: Current Setup Infrared satellite shows the […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]
