Region 1
An intensifying area of low pressure and its associated cold front will track northeastward across the Great Lakes today. As this occurs, instability is forecast to increase ahead of this cold front. With strong wind shear in place, strong to severe thunderstorms will increase in coverage and intensity this afternoon and evening. Initially, a few supercells and some squall lines will be possible. Heading into the evening, this activity will transition into a larger squall line ahead of the cold front. During the afternoon hours, large hail, damaging winds, and tornadoes will all be potential hazards with any storms that develop. Once thunderstorm activity evolves into a squall line, damaging winds and isolated tornadoes will be the primary hazards.

A Look Ahead
Model guidance continues to indicate the potential for wintry weather across northern portions of the US on Tuesday. An area of low pressure is forecast to lift northeastward toward the Upper Midwest throughout the day, with accumulating snow expected to develop over northern portions of the low. While confidence is not high due to the time frame as well as some model discrepancies, there appears to be a potential for a few to several inches of snow across North Dakota eastward into Minnesota.
