A slower moving storm system will impact the Pacific NW, central and northern Rockies this weekend into early next week. Forecast models show a deep area of Low-pressure will move into Washington and Oregon on Saturday and dig into northern Utah and finally ejecting into the Dakotas early next week.

Although the storm should track mostly south of our region that doesn’t mean we are in the clear. In fact, to be on the northern edge of a storm like this should produce widespread snow over southern Montana. Plan on hazardous travel conditions to return by Sunday through Tuesday of next week.

After this Low moves out a shot of Arctic air will dig down into Montana producing well below normal temperatures throughout next week across the entire state.
