STURGIS, S.D. - An Alberta clipper blew through the area Wednesday night, dropping snow and the temperature.
The National Weather Service on Thursday issued wind chill advisories and warnings throughout North Dakota and South Dakota into Friday morning. Forecasters said wind chills in some areas could drop to as low as minus 55 degrees — conditions in which frostbite can occur within minutes.
Many schools around South Dakota either called of classes or started late on Thursday due to the cold.
A winter weather advisory also was posted for the northern Black Hills of South Dakota early Thursday.
The National Weather Service says snow totals ranged from 5 to 7 inches around the Black Hills. Piedmont reported 5 inches of snow, Cheyenne Crossing had 7 inches, three inches fell at Saint Onge, and Deadwood reported 6 inches.
Around the Sturgis area, between 4 and 5 inches of snow was the best guess becuase the wind blew a lot of it around. Drifting snow was reported within the city of Sturgis, along with plenty of icy roads. The Interstate between the Wyoming state line and Rapid City was in pretty good shape by Noon Thursday, with some areas of ice and snow cover.
The forecast calls for much warmer temperatures in both states by the weekend as the arctic air moves out.
