Blizzard Conditions in Portions of South Dakota, Minnesota
According to the National Weather Service, a storm system in the Northern Plains and Upper Midwest is producing snow and strong winds across portions of the Dakotas and Minnesota. Winds will gust up to 45 mph in this area, with blowing snow contributing to blizzard conditions. Travel across this region will be hazardous with reduced visibilities and snow-covered roads.
Low pressure continues to move off to the east and the snow has about ended across the area. However wind speeds remain strong. Northwest winds will continue along the red river valley at 30 to 40 mph with higher gusts. These winds will continue to produce low visibilities due blowing snow into the early evening especially in open areas. As temperatures fall wind chills will also become quite chilly.
The National Weather Service in Grand Forks has issued a winter weather advisory for blowing snow and cold wind chills, which is in effect from 6 pm to 9 pm Monday evening. A blizzard warning remains in effect until 6 pm Monday evening.
In Sioux Falls, scattered evening snow showers and flurries will be possible across portions of the area with clearing skies expected by later Monday night.
Winds will remain blustery with gusts up to 45 mph into this evening, before dissipating into the 15 to 30 mph range for the overnight into Tuesday morning.
It will be a cold night, with lows ranging from the single digits below zero in the north, to the single digits above zero in the south. These cold temperatures combined with the blustery winds will result in dangerous wind chills of 20 to 30 below zero across the north.
It will be mostly sunny Tuesday, but continued cold conditions can be expected, with highs in the single digits and teens.
Snow is expected to overspread the area from southwest to northeast late Wednesday night into Thursday, before tapering off Thursday night. Accumulations of 4 to 8 inches seem possible over a large area.
