..Potentially hazardous wind chills this week

Each overnight and morning period will hold some potential for seeing wind chills between 30 to 40 below zero this week through Saturday.

Modified arctic air mass will linger of the area through this time before influence from milder air mass originating from the Pacific overspreads our region around Sunday. Temperatures each night will be subzero, with teens below zero favored more into the Devils Lake basin and along and just east of the Red River Valley in Minnesota.

This includes tonight into Wednesday morning where chances for these hazardous wind chills is greater than 80% in these same locations. A Cold Weather Advisory has been issued for this.

Otherwise, the chance for these wind chills is around 50% Wednesday overnight into Thursday, with perhaps higher chance closer to 70% Thursday overnight and Friday as a less modified arctic air masses settles into the region bringing better chance for temperatures teens to twenties below zero.

Uncertainties mainly stem from subtle differences in wind speed as well as cloud cover that may limit how cold temperatures get.
