Snow likely Saturday in southern MN; cold continues

Clear skies and nearly calm winds helped to create an ideal set up to radiate warmth back to space last night. At the same time, cloudiness persisted in the Twin Cities metro area, where overnight lows dropped down to around 10 degrees.

Low temperatures reported overnight in Minnesota through 6 a.m. included 8 degrees below zero at Benson, Little Falls, and Rice.  It was a nippy 6 below in Willmar, 4 below at Princeton and 3 above at St. Cloud.

There appears to be a consistent expansion northward of the expected snowfall on Saturday. Given the relatively cold air mass and the expected long duration of the light snow, accumulations by late Saturday night may exceed 4 inches in portions of southern Minnesota.
