High pressure building into the Northland will lead to a frost and freeze across much of the region. As skies clear out temperatures will fall to near freezing overnight, which could damage any tender vegetation left outside without protection.
Temperatures are expected to fall near and below freezing after midnight tonight, resulting in frost advisories and freeze warnings to be issued from North Dakota back through Wisconsin.
The frost advisory is in effect from midnight to 8 a.m. Friday. Temperatures are expected to drop into the mid-to-low 30s, possibly killing plants if precautions aren’t taken. Locations in the freeze warning will have overnight temperatures in fall into the 20’s.
