A band for light snow over far southern Minnesota at daybreak left as much as two and a half inches on the ground in favored locations.

The visible satellite image from 3 p.m. CST showed clouds continuing to thin out during the afternoon hours.  Clearing skies and diminishing winds should allow for radiational cooling overnight. Sub-zero temperatures are most likely over the snow cover in far northern Minnesota.
