Snow will develop late tonight in western South Dakota and move into central KELOLAND on Thursday. Eastern South Dakota will stay dry tonight and much of Thursday, but light snow will be possible east of the James River Valley toward sunset. Snow amounts of one to three inches will be possible from Rapid City to Pierre and south tonight and Thursday. Eastern KELOLAND’s snow will be minor with some areas only picking up an inch or two Thursday night and into early Friday. Highs Thursday will be below average with highs only in the teens to near twenty. The cold air will stay with us for Saturday, but Sunday will bring a slow warm-up to KELOLAND with highs in the upper twenties in Sioux Falls to lower thirties in Rapid City. Aberdeen and Pierre will still have temperatures in the teens, but slowly warmer temperatures will move in early next week.
