Snow in northern Minnesota, then bitter cold for Easter weekend and the start of Passover. The National Weather Service predicts a half-foot of snow from central Minnesota into the Arrowhead beginning tonight, with heavier amounts along a line from Moorhead to Brainerd to south of Duluth. The snow is expected to end tomorrow and then it turns windy and unseasonably cold, with overnight lows on Saturday night from zero to three-above in the north, nine to 15 in the south. Forecasters say single-digit lows will hang on in northern Minnesota through the early part of the week.
