The southern row of counties are under an extreme cold watch for dangerously cold wind chills expected late Sunday to Wednesday morning. During that time period wind chills are expected to be as cold as 25 degrees below zero. This is the first issuance in Michigan of the new extreme cold watch.

(CBS DETROIT) — Dangerous cold will move through the Southeast Michigan region Monday through Wednesday next week. Cold Arctic air dives south this weekend, with temperatures falling into the teens on Sunday at the very start.

An Arctic air mass, sometimes known as a Siberian Express, is expected to move over Michigan by Sunday and will leave Michigan residents with below-zero temperatures for days, the National Weather Service said.

Arctic air is going to move into Michigan early next week. The cold air will come with some wind, making dangerously cold wind chills. The Arctic air will be steadily infiltrating Michigan’s air Sunday and Monday with the coldest temperatures Tuesday and early Wednesday morning.

Michigan schools typically close when wind chills reach 20 degrees below zero. Next week's weather is expected to approach that threshold.

Single digit high temperatures and sub-zero lows early next week will be West Michigan’s coldest air mass in six years.
