The Week Ahead

Tomer’s Take: Snow in the Wasatch and Colorado ends tonight with another 1-3 inches in the Tetons. The next storm system arrives 2/19-2/22 in UT/CO/ID/WY with moderate to heavy snow accumulation. Big totals possible 2/25-2/28 with northern jet involvement and energy.

My afternoon forecast video update:

Current Setup

Water vapor satellite shows a large trough of low pressure sending waves of energy into the Intermountain West. The entire trough moves into CA 2/19-2/20 with heavy snow accumulation across the Sierra. Then it hits UT/ID/WY/CO 2/20-2/22.

Orange/red = drier air aloft.

Forecast Radar & Satellite

Forecast Totals

Grand totals by late 2/27.


VT/NH/ME light snow accumulation PM 2/22-2/23. Another storm system around 2/27.

Fading El Nino

BTW, EL Nino is fading quickly. We’re officially under a “La Nina Watch”. Neutral conditions by May and La Nina by Summer.

This will slowly shift the pattern for the Western United States. I think we’ll still have a solid March across UT/ID/WY/CO.

Colder values represent La Nina.
