A blizzard watch has been issued for Sunday and Sunday evening across most of west central and south central Minnesota.
The National Weather Service said two to four inches of fresh snow is expected to fall on the region Saturday night, followed by plunging temperatures and winds of 25 to 35 mph through much of Sunday. Some wind gusts could be as high as 50 mph.
The combination of snow and strong northwest winds will cause blowing and drifting snow and whiteout conditions, making travel difficult on Sunday.
The blizzard-like conditions will be worst along and southwest of a line from Long Prairie in central Minnesota through Litchfield and south to St. Peter and Owatonna. The Weather Service said the wind will start to diminish after midnight Sunday but areas of blowing and drifting snow could persist into Monday.
Another polar plunge in temperature also is anticipated. Highs will start in the teens and lower 20s on Sunday, then drop to subzero readings by evening. Overnight lows could fall into the range of 15 to 25 below by Monday morning, accompanied by dangerously cold wind chills.
