The weather’s been pretty active lately, and it doesn’t look like it’s calming down anytime soon.
Today, a pair of low-pressure systems stretch from eastern Colorado to northern Missouri, with a strong warm front cutting across north-central Illinois, creating a sharp temperature contrast—from the upper 30s in Chicago to around 80 degrees in Peoria.
Tonight, severe thunderstorms are possible, with a chance for a few strong tornadoes from the southern Plains to the southern Great Lakes, while the colder side of the system will bring accumulating snow to parts of the upper Midwest.
Here’s my snowfall forecast through 7 AM Wednesday.
Eastern Minnesota and much of northwest Wisconsin could see 3 to 6 inches of snow from tonight’s system, while Duluth may get 1 to 3 inches, with totals tapering off to an inch or less farther north.
For Duluth: Snow will fall tonight, tapering off between 4 and 7 AM Wednesday. Gusty east winds at 15 to 30 mph this evening will shift to the north-northwest overnight. Expect some patchy blowing snow tonight, with Wednesday staying mostly dry and temperatures in the 30s.
HRRR model simulated radar forecast through 7 AM Wednesday.
Much like last night, strong frontogenesis is developing from central Minnesota to northern Wisconsin, and this enhanced FGEN forcing could bring some heavier bursts of snowfall tonight.
…Winter Weather Alerts for tonight…
Tonight’s system, while fairly strong, could have been even more intense if the two troughs had merged sooner. One trough is digging east-southeast out of the northern Plains, while another, the remnants of the Baja upper low from the past few days, is moving east-northeast across the southern Plains.

…Late Week Snow Chances…
A strong clipper system may bring another round of accumulating snow to much of northeast Minnesota and northwest Wisconsin from Thursday afternoon into early Friday morning.
The track of this low differs quite a bit between models, with some showing it moving farther north and staying north of Duluth, while others show it tracking farther south and passing south of the city.
With the low tracks varying, snowfall amounts are uncertain. If the low moves on a more northerly path through far northern Minnesota or southern Ontario, Duluth could see less snow later this week.
Temperatures on Thursday will likely vary widely, from near 70 degrees in southern South Dakota to the mid-20s and low 30s in northern Minnesota. This sharp contrast will only add more intensity to the system.
…Weekend Storm Chances…
I should also mention the system for this weekend, as there’s been plenty of chatter about a potential storm. Right now, the computer models don’t agree. The Euro is one of the few showing a significant winter storm hitting parts of the Northland, including Duluth, while the GFS keeps it much farther south with little to no snow for our area. Interestingly, the AI versions of both the Euro and GFS also keep the system away from the Northland. We’ll just have to see which way the models trend in the coming days, but for now, the Euro stands alone in predicting a pretty significant winter storm from late Saturday into Sunday. Stay tuned.
