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 feet.
My forecast video 1/20:
Water vapor satellite shows the shifting storm track out West.
Forecast jet stream valid 1/29. Notice the fast jet stream running N-S through MT, WY, UT, CO.
Below is the EPS forecast atmospheric pressure anomalies (mid atmosphere) valid late 2/3. The high pressure ridge retrogrades towards the Bering Sea allowing lower pressures to build across the West.
Forecast radar/satellite valid 1/20-1/25.
Forecast snow totals (inches) valid 1/20-1/22.
Forecast snow totals (inches) valid 1/23-1/29.
