Minnesota Storm Update: Thundersnow and Up to 10 Inches Expected
A Winter Strom Watch is in effect late Tuesday night through late Wednesday night across SE Minnesota with possible blizzard conditions and heavy snow.
A powerful spring storm is set to move through the Midwest bringing a mix of rain, thunderstorms, gusty winds, and significant snowfall to parts of SE Minnesota and Western Wisconsin.
UPDATE: (3/18/25 7:11 AM): New Snowfall Prediction & Blizzard Warning Issued Ahead of Incoming Minnesota Storm
The NWS warns that this system presents forecasting challenges due to sharp temperature contrasts across the region. On Wednesday, temperatures could be in the 60s in southern Wisconsin while dropping into the low 30s just a couple of counties away in southeast Minnesota.
This extreme difference increases the potential for thundersnow (when a thunderstorm produces snow instead of rain), rapidly changing conditions and fluctuating travel impacts.
What to Expect With This Winter Storm in Minnesota
According to the National Weather Service, the heaviest snow is expected in a narrow band from Rochester to Owatonna, down to Austin, where totals could range from 5 to 10 inches.
An updated map from the National Weather Service in La Crosse now shows surrounding areas, including Wabasha, Winona, and Preston, may see lower snow totals of 2 to 7 inches, and Faribault is now in the 5-11 inches range, while the Twin Cities metro is expected to receive 2 to 8 inches.
Strong winds could accompany the snowfall, leading to blowing and drifting snow, especially in open areas. Road conditions will vary depending on temperatures, with some locations experiencing slick and snow-covered roads.
Why This Storm is Tricky
According to the NWS, this storm system is currently 700 miles off the northern California coast, making the exact path and snow amounts subject to change.
Spring snowstorms often pull in high levels of Gulf moisture, which can lead to unexpectedly high snowfall rates, NWS says.
Stay Prepared During Spring Storms in Minnesota
With potential travel impacts late Tuesday night through Wednesday night, the NWS urges residents to keep an eye on forecast updates, prepare for quickly changing conditions, and plan for possible delays and hazardous driving conditions.
