CHANHASSEN — There’s a winter storm warning through tomorrow (Sat) morning across southern Minnesota, and then comes the first brutal cold of the season. The National Weather Service says there could be four or more inches of snow across southern Minnesota — possibly as much as eight inches in southeast Minnesota’s Goodhue County, and three to five in the metro with heavier amounts into Wisconsin, but less to the west around Hutchinson, Olivia and Redwood Falls. Then temperatures will plummet: Lows 9- to 15-below zero by Saturday night, continued cold Sunday and by Monday, M-L-K Day, highs only 3-below to 9-below.
