The warmer air that will be in place today will be a welcomed sight by most, but for the most part it will only be temporary.  A stiff west/northwest wind will usher in much warmer air to the region today with widespread 20s and 30s expected for afternoon highs with the snow free locations in western North Dakota reaching the 40s.

The warm up with be brief as a cold front through central Canada will blast across North Dakota on Tuesday morning.  Because of the timing of the next front, temperatures will drop perhaps 10° as the front moves (from 20s to 10s for many) through but then remain fairly steady the rest of the day.

Canadian Surface Analysis




Cloud cover associated with a clipper system that will move across western and central North Dakota into central and eastern South Dakota will likely keep temperatures from dropping much on Tuesday night into Wednesday morning, therefore, the true affects of the cold front on temperatures may not be felt until Thursday and Friday morning.

Potential snowfall is presented in the graphic below for Tuesday Night into Wednesday.   Other areas may record snowfall, but under 1 inch.
