Brutal Arctic Air Blankets Entire Minnesota

|


The brutal northern blast of arctic air is blanketing the entire US this weekend, including Minnesota, with air temperatures ranging -20F to -50F. This first coldest air of the season is expected to reach southern states like Texas.

Temperatures could drop as low as 20 to 30 degrees below zero in the northern Plains both Friday and Saturday night and combine with gusty winds to make for frigid wind chills as low as 50 degrees below zero. And the cold is expected to test Texas’s notoriously vulnerable-to-extreme-temperatures power grid for the first time this winter.

Brett Borchardt, meteorologist for the National Weather Service office in Chicago told CNN, “Chicago hasn’t had a high temperature below freezing since November 28. Wind chills on Monday in Chicago will be near or below minus 30 degrees, comparable to the 2017-2018 cold snap.”

Starting today, cold winds are expected to increase with falling temperatures in Minnesota, including the Twin Cities. MPR News reports that Friday’s wind will range from 15 to 30 mph from the north by the afternoon.

High temperatures will still be above zero Saturday in most of eastern Minnesota, but will struggle to reach zero Sunday and remain subzero for most of western and northern Minnesota. Overnight lows will be well below zero by Saturday and Sunday nights with western Minnesota seeing subzero readings Thursday and Friday nights as well.

Winds will remain elevated through the weekend so wind chills will be a major concern. Sunday morning wind chills will be as cold as 40 below zero in western Minnesota.
