Snow Storm Update 2.22.13

Another cold night expected across the region, with lows ranging from the negative teens along the highway 14 corridor, to around zero along the Missouri river. Wind chills will continue to range from 20 to 30 below zero across portions of southwest Minnesota through the night. Attention then turns to our winter storm on Thursday. Timing is a bit slower, with accumulating snow expected to start in our west around midnight, but not until early to mid afternoon across southwest Minnesota. Total snow amounts are expected to be highest west of the James river closer to the Missouri river, where 5 to 10 inches are possible. Amounts will generally decrease as you head northeast, with 3 to 8 inches across most of southeast South Dakota into southwest Minnesota.
