The season’s first outbreak of freezing, Arctic air is headed for the United States this weekend into next week. It will register as the most unusually cold blob of air on the planet for a time.
Chilly air will reach the Plains and Midwest this weekend before spreading to the East Coast on Monday. In total, 155 million people across the contiguous states are expected to experience freezing conditions through Wednesday.
Across parts of Michigan, possibly including Detroit, the arrival of the cold wave may be marked by a period of snow early Sunday — the first of the season. From Sunday into Monday, snow showers and squalls could stretch from the Upper Midwest to the southern Appalachians — with flurries possibly reaching the Mid-Atlantic on Monday night.
The cold air will also spark the development of lake-effect snow bands. The contrast between near-record warm Great Lakes water temperatures and the unusually cold air mass above will be substantial, contributing to more atmospheric instability and the potential for locally heavy snow bands in Michigan, Ohio, Pennsylvania and New York from Monday to Wednesday.
Swaths of accumulating snow are likely from the Dakotas to Maine, southward into the Ohio Valley and Appalachians as well as around the Great Lakes from Saturday to Wednesday.
Wet snow may fall in areas including Michigan; Ontario and Quebec, Canada; northern New York; and New England from Sunday into Monday.
