Dangerous wind chills filtered in across the upper Midwest early Thursday. Air temperatures fell below zero but the wind chills sat down near -20 to -35 which prompted the WIND CHILL ADVISORY for the Chippewa Valley through 10 a.m.
Frostbite times are around 30 minutes or less when wind chills hit -30 degrees, so make sure to cover as much skin as possible if you'll be outside for an extended period of time.
Even after the advisory expires wind chills won't get above the negative teens. Wind speeds will be from 5 to 15 mph out of the northwest. Air temperatures will try to get above 0 Thursday afternoon, but they'll quickly drop back into the negatives overnight.
This very cold arctic high pressure system will bring plenty of sunshine to the region Thursday and Friday. But the coldest air associated with this arctic pool will hit early Friday morning. Air temperature will be between -15 and -25 degrees. Any light wind will make wind chills feel below -30.
The next shot at snow will be on Saturday but those chances are slight. We'll probably see flakes but snow totals will be minimal. Temperatures will go back into the 30's Saturday before falling back into the 20's on Sunday.
