MADISON, WI – Southern Wisconsin is bracing for its first significant winter storm of the season as a powerful system approaches the region. The National Weather Service (NWS) has issued a Winter Storm Watch for a wide stretch of southern and southeastern Wisconsin, including Madison, Milwaukee, Waukesha, Janesville, and Kenosha, from late Friday night through late Saturday night.
Residents across the region are being urged to prepare for 6 or more inches of snow, difficult travel, and rapidly changing weather conditions as this early-season storm makes its way across the state.
Heavy Snow Forecast Across Southern Wisconsin
Meteorologists say this system has the potential to bring widespread, impactful snow across the area during one of the busiest post-Thanksgiving travel weekends. Early forecasts suggest that snowfall totals may exceed 6 inches in several counties, with the highest accumulations expected in portions of south-central and southeastern Wisconsin.
According to the latest outlook from the National Weather Service, the storm will spread snow across the region beginning late Friday night and continuing into Saturday.

This system is expected to intensify during the daytime hours on Saturday, leading to steady, moderate-to-heavy snowfall across populated corridors.
Timeline of the Winter Storm
Forecasters are tracking the system’s path and providing a detailed timeline of what residents can expect:
- Late Friday Night: Snow begins moving into the state from the southwest.
- Saturday Morning to Afternoon: Heaviest snowfall rates expected, creating significant travel disruptions.
- Saturday Evening: Snow transitions to light snow or flurries.
- Sunday Morning: System gradually exits, leaving behind cold air and lingering slick conditions.
While most areas will see primarily snow, far southeastern counties may experience periods of sleet, which could further complicate travel.
Travel Impacts Expected on Major Routes
With snow arriving at the end of a holiday week, the timing could not be worse for travelers heading home. Officials warn that conditions may deteriorate rapidly, particularly on major highways such as I-94, I-39, and Highway 12.
Bold facts to note:
- 6+ inches of snow possible
- 25 mph wind gusts expected
- Watch effective Friday night–Saturday night
- Impacts likely in Madison, Milwaukee, Waukesha, Janesville, Kenosha
Gusty winds may also create blowing and drifting snow, significantly reducing visibility across rural stretches and open fields.
What Authorities Are Advising
State and local officials are urging residents to take precautions ahead of the storm. Travelers in particular are being told to adjust schedules if possible.

The NWS emphasizes that hazardous conditions could extend into Saturday evening and early Sunday as crews work to clear snow-covered roads.
Early-Season Cold Snap to Follow
Even after the snow ends, winter weather will continue. Behind the storm, temperatures are expected to drop into the upper 20s and low 30s, ushering in a classic early-December chill. Forecasters say this system could signal the start of a colder, snowier pattern that may persist into next week.
This colder stretch will increase the likelihood of icy patches on roadways, particularly overnight and during early morning hours.
How Residents Can Prepare
As the storm approaches, winter readiness becomes crucial. Officials recommend taking the following steps:
- Complete holiday travel by Friday afternoon to avoid deteriorating conditions.
- Prepare vehicles with winter tires, emergency kits, blankets, and a full tank of gas.
- Stay updated with local advisories and weather alerts through Saturday.
- Clear sidewalks and driveways early to prevent dangerous ice buildup.
- Check on elderly neighbors or those with mobility issues.
Winter weather risks rise significantly during the season’s first major snowfall, making extra precautions essential.
Conclusion
Southern Wisconsin is gearing up for a potentially impactful winter storm that may bring 6 inches or more of snow, reduced visibility, and challenging travel conditions through Saturday. With busy roads, post-holiday travel, and early-season cold, residents are urged to prepare carefully and stay alert to weather updates over the coming days.
