WILLMAR – A wind chill advisory has been extended for most of Minnesota through Wednesday morning and a winter storm watch has been issued for Thursday and Friday.
Dangerously cold wind chill values of 20 below to 35 below will persist across all of west central Minnesota through tonight, with brisk northwest winds of 15 to 20 mph continue, according to the National Weather Service in Chanhassen.
The winds will decrease overnight from west to east, but temperatures will be colder than last night. Thus wind chill values will once again drop to less than 20 below zero across most of southern Minnesota.
The National Weather Service has also issued a winter storm watch from Thursday evening through Friday afternoon, generally along and south of Interstate 94. This includes all of west central Minnesota.
Snowfall amounts exceeding six inches are expected Thursday, especially along and south of a line from Morris to the Twin Cities metro to Eau Claire, Wis. and then spread northward in central Minnesota.
Snow fall will begin in southern Minnesota by late Thursday afternoon and then spread north and east into central Minnesota and Wisconsin.
The snow will continue Friday, with amounts over six inches possible by Friday afternoon. The greatest snowfall accumulations will occur along Interstate 90 in south central and southwestern Minnesota.
