Frigid Temps, Dangerous Wind Chills in South Dakota
SIOUX FALLS - Frigid temperatures have moved into the Dakotas as an arctic air mass continues to spread across the region.
The National Weather Service says below-normal temperatures are expected to continue through at least Tuesday morning.
The coldest wind chills are in western and central North Dakota. The Weather Service says the wind chill dropped to -47 near Pierce and -42 degrees near McHenry and Sheridan overnight.
In South Dakota, dangerous wind chills are expected through Monday evening thanks to low temperatures and northwest winds of 10 to 20 mph. The combination is producing wind chills from -20 to -40.
