Fast NW Flow for the West; 2-3 storm systems NE

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.
