Frigid arctic airmass remains over the Northland, and it will stay put through Saturday. The good news is that will have a lot of sun once again Friday, but temperatures won’t be warming up just yet. Back to today for a moment, mainly sunny skies while high temperatures were in the single digits below to single digits above zero, well below normal for early January.
Tonight through Friday night: Dry with clear to partly cloudy skies. Lows tonight and Friday night will be in the teens, 20s and 30s below zero with 40s below possible both nights in the typical cold spots. Highs Friday in the single digits below to single digits above zero.
Note: Chance for some light snow or freezing drizzle in the Northland Saturday night as warmer air pushes into the region as a warm front and cold front move east into the northern Plains. Snow amounts should remain on the light side, probably in the half inch to two inch range the way it looks now, with the greatest chance for up to two inches of new snow occurring north of Duluth.
Note: There is another chance for some snow or mixed precipitation during the middle of next week, around the 10th-11th, but once again we’re looking at mostly light precipitation amounts.
