Chilly this morning, even colder Tuesday morning

Temperatures dropped into the single digits early Monday morning with brisk northwest winds driving wind chill readings below zero in northern Minnesota.

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.


Temperatures didn’t move much today.  Highs topped out near 20 in the far north to lower 30s in the far south.
