Minnesota air bites your face the moment you step outside in Duluth this morning. The thermometer sits at 18 degrees, and a northwest breeze makes it feel closer to 4 above. Frost clings to railings along Lake Superior, and exhaust hangs thick in the still air.
Skies stay sunny today, but the winter chill refuses to budge much. Highs reach only around 30 degrees this afternoon. Roads remain dry, yet shaded spots could stay slick where compacted snow lingers. This is the time of year when subtle melting and refreezing create isolated icy patches.
Tonight turns sharply colder. Temperatures fall to around 14 degrees under partly cloudy skies. Any moisture on sidewalks can refreeze quickly after sunset. Watch for slick driveways and untreated side streets by early morning.
A gradual February thaw begins Thursday. Highs climb to 33 degrees with mostly sunny skies. By Friday, temperatures jump to near 40 degrees under sunshine. Valentine’s Weekend stays seasonably mild, with highs in the upper 30s to near 41 by Sunday.
No major snow is expected through the weekend. However, small melt-and-freeze cycles may continue at night as lows dip into the 20s. That pattern can quietly increase slip-and-fall risks.
Early next week keeps temperatures near or slightly above average. Long-range signals hint at a broader warm-up across much of the central U.S., with milder air expanding into the Upper Midwest. While not a full spring tease yet, the trend favors less bitter cold into the 6–10 day outlook.

Today: Sunny, high near 30.
