Mankato, Minnesota – Southern Minnesota is preparing for the first major winter storm of the season as a long-duration system moves into the region Friday evening. Forecasters warn that the storm could bring 5 to 8 inches of snow, falling temperatures, and hazardous travel conditions stretching from Redwood Falls to Albert Lea through Saturday night. Officials say the storm’s timing—arriving just as weekend and post-holiday travel ramps up—may create additional challenges for residents.
Winter Storm Watch Issued for 10 Southern Minnesota Counties
The National Weather Service Twin Cities/Chanhassen has issued a Winter Storm Watch for Redwood, Brown, Nicollet, Watonwan, Blue Earth, Waseca, Steele, Martin, Faribault, and Freeborn counties from Friday evening through Saturday evening.
Forecasters explain that snow will begin pushing in from the Dakotas shortly after sunset on Friday before spreading across most of southern Minnesota overnight. According to early projections, the heaviest snowfall is expected to fall near Mankato, St. Peter, Waseca, and Owatonna, where totals could reach the upper end of forecast estimates.
A detailed outlook from meteorologists notes that once snow begins, it will likely intensify during the overnight hours. As temperatures fall below freezing, untreated roads may quickly become slick and visibility is expected to drop.
Timeline: Snow Arrives Friday Night and Peaks After Midnight
Forecasters say residents should expect the first wave of snow to begin in the early evening Friday, with steadier and heavier snow arriving after midnight.
Snowfall rates may increase rapidly, and this could cause significant road coverage by early Saturday morning.
“Travel impacts are likely Friday night into early Saturday as temperatures drop and snow begins to accumulate on major highways,” forecasters said in a briefing.
By Saturday afternoon, the storm is expected to gradually weaken, though scattered light snow may continue into the evening before tapering off completely.
Hazardous Travel Expected Across Major Highways
Travel is expected to be one of the biggest concerns as strong winds combine with falling snow.
Meteorologists warn that blowing snow could become a significant issue along exposed routes, particularly US-169, US-14, and I-35. Areas south of Owatonna and west toward Fairmont may see reduced visibility and drifting on rural stretches.
Emergency management officials are urging drivers to plan ahead and avoid unnecessary trips during the heaviest portions of the storm.
“Motorists should prepare for slow travel, carry emergency kits, and consider adjusting return plans from holiday gatherings,” officials noted.
Crews plan to pretreat major routes Friday afternoon. However, officials caution that rapid overnight accumulation may outpace early plowing efforts, creating challenging conditions for morning travelers.
Key Safety Measures Residents Should Take
As snow and temperatures drop into the teens and low 20s, safety experts recommend Minnesotans take extra precautions. Residents are encouraged to charge phones and essential devices, secure loose outdoor items, and ensure pets have proper shelter during the cold snap.
To reduce strain, residents should consider shoveling in intervals rather than waiting for total accumulation. Early clearing helps prevent heavy buildup and makes walkways safer.
Weather specialists also advise the following winter-preparedness steps:
- Check local forecasts regularly for updated snowfall totals
- Keep winter tires properly inflated
- Allow extra braking distance while driving
- Store blankets, flashlights, and jumper cables in the vehicle
- Clear sidewalks to prevent ice formation
Broader Weather Context and Seasonal Awareness
While fall snow events are not unusual in Minnesota, long-duration systems like this often signal a shift toward more persistent winter weather patterns. Early-season storms can be particularly impactful because residents are still transitioning from fall routines and may not have fully prepared vehicles or driveways for heavy snow.
Experts emphasize that wind, visibility, and temperature swings—not just snowfall totals—are all key factors contributing to dangerous travel. Even at moderate snow depths, untreated roads can become icy quickly when temperatures fall into the teens.
Conclusion
Southern Minnesota residents should stay alert as the region prepares for the approaching winter storm. With 5–8 inches of snow, strong winds, and freezing temperatures expected, forecasters and officials urge the public to plan ahead, drive cautiously, and put safety measures in place at home and on the road.
