Area Forecast Discussion National Weather Service Duluth MN 528 PM CST Tue Feb 10 2026
KEY MESSAGES
- Light snow showers will end this evening
- Above normal temperatures will lead to daily highs above freezing, leading to thawing and refreezing across the region.
- Dry conditions after today will continue until this weekend.
DISCUSSION
Issued at 115 PM CST Tue Feb 10 2026
A secondary trough associated with a clipper up in Ontario has brought enough lift to generate some light snow showers across the area. The bulk of these are up in the arrowhead where the best forcing and moisture are. Dry air will continue working its way in from the east, so snow shower activity should continue to diminish into this evening, but with a few snow showers perhaps lingering in the Arrowhead tonight with some low-level moisture and instability remaining. At the most, expect a dusting of snow and some briefly reduced visibilities from some of these, but most places will simply continue to see a few snowflakes in the air here and there before they end.
Outside of the snow showers, post-cold frontal winds have been blustery today and they will gradually decrease in speed overnight.
Downsloping winds along the North Shore will remain a bit gusty tonight (up to around 25 mph), but less wind elsewhere.
Broad ridging to our west will dominate the weather pattern the rest of the week, into this weekend, and possibly into early next week as well. Surface high pressure will settle over us for Wednesday, leading to plenty of sunshine and light winds. We will get into a dry southerly flow regime Thursday and Friday. Temperatures are looking to be pretty balmy for this time of year with highs in the 30s and 40s. There may be a brief, and likely dry, clipper passing through around Saturday, followed by more warm southerly flow. So, expect the warm weather to continue into the weekend and into next week. It wouldn't be surprising if we see a few places in east- central MN into northwest WI hitting 50 on one or two of these days, as is often the case with these late-winter warm ups. The other thing to keep in mind is that overnight lows will be below freezing every night, so the freeze-thaw cycle will result in some messy and icy conditions for untreated surfaces (probably not so much roadways, but driveways, sidewalks, decks, etc.).
As we look further out, a pattern change might be coming as broad troughing could potentially replace the ridging over the west. This would put us into more of a southwest-to-northeast storm track and favor more Colorado lows over the upper Midwest perhaps late next week. This doesn't guarantee anything for the Northland, but odds may tilt slightly more in the favor of storm systems that could produce more noteworthy rain and/or snow than we've seen in the past couple weeks or so.

Departing low pressure system this evening has some trailing stratus lingering across the region. With moisture still in the area more MVFR ceilings will be possible tonight. Satellite also shows a region of of low MVFR over the Red River Valley, if this holds together it would impact BRD later tonight as well. High pressure builds in tomorrow with dry air and light winds becoming the prominent features in the afternoon.
MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/
Issued at 115 PM CST Tue Feb 10 2026
Breezy conditions will persist into this evening. No changes to current headlines as wind speeds and gusts have been hovering in the 20 to 25 kt range for the most part early this afternoon.
Expect winds to remain breezy for a few more hours, but gradually start to decrease in speed into the evening and overnight. On Wednesday, winds become westerly to southwesterly and gusts should decrease below 15 kt as high pressure moves in.
Light to calm winds are expected into Thursday. Winds are expected to remain pretty tame going into the weekend as well.
