Another strong shot of autumn weather invades the Great Lakes and Upper Midwest this week. It’s the third such weather system to plow into the northern tier of the U.S. in the past two weeks.
The same system that brought record low temperatures in the 30s and colder to places in Wyoming and Montana on Sunday, is moving eastward on Monday into the Western Great Lakes region. The forecast high in Minneapolis on Monday will only be 68 degrees, which is 12 degrees below normal. The cool pocket of air will eventually stretch across the entire Great Lakes region, plunging high temperatures 10 to 15 degrees below normal for places like Buffalo, New York; Cleveland, Ohio; Detroit, Michigan; and Chicago, Illinois.
The forecast calls for Chicago to stay in the 70s for the entire upcoming week. Cleveland is forecast to stay below normal until at least Saturday. Duluth, Minnesota will struggle to get into 60s Monday as the core of the cool air passes through.
