Snow and blizzard conditions possible tomorrow, then bitter cold

Snow to a wintry mix moves in later tonight, changing to snow early Thursday. Travel conditions will deteriorate Thursday. By later afternoon, blustery northwest gusting 30 to 40 mph will cause blowing and drifting snow, and possible ground blizzard conditions.

Details continue to evolve on the storm track and strength. Thus, expect a few more changes to the forecast as Thursday approaches.

A blast of Arctic air then moves in for the weekend. Wind chills will likely be dangerously cold at times, especially Sunday and Monday mornings. Temperatures will likely stay abnormally cold through the new work week.
