A frigid air mass moving from the Arctic will bring snow squalls and below-freezing temperatures to the Great Lakes region this weekend. The cold air will persist into early next week, with daytime highs expected to drop below -10 C.
This weekend, very cold air will migrate from the Arctic, down through the Canadian Plains, and into the Great Lakes region. The dry air and northerly winds associated with this air mass will stop the squalls by the end of this weekend and bring sunshine for next week, but temperatures will be well below normal for early January. On Friday, the winds will become more northerly and should push the squalls into Michigan as daytime highs fall to -6 C.
The gusty winds will keep windchill values below -15 all day. We will see snow squalls move back into the region in the evening as winds shift to the northwest again, with 5-10 cm possible overnight. Snow squalls continue Saturday afternoon as the winds remain northwest, bringing another 5-10 cm of snow. Afternoon temperatures will be near -6 C, and windchill values will be near -15. Sunday will be cloudy as squalls end, with daytime highs again near -7 C. The sunshine arrives early next week but comes with much colder air and daytime highs below -10 C
