A broad period of active weather is taking shape for southern Wisconsin, bringing rounds of showers and thunderstorms through the coming week. The forecast points to a mix of non-severe storms, a higher potential for severe weather on ALERT DAYS, and notable wind and rainfall amounts.
Residents should stay tuned to local forecasts and use alerts to stay ahead of rapidly changing conditions.
Upcoming Weather Outlook for Southern Wisconsin
The next several days will feature repeated opportunities for rain and a few thunderstorms as a low-pressure system deepens and tracks through the region. Temperatures will rebound into the 70s and near 80°F at times, with increasing humidity feeding the potential for stronger storms.
Forecast confidence remains moderate. Several rounds of showers and thunderstorms are likely, with gusty winds and heavy rainfall possible in stronger cells.
A period of calmer weather is anticipated later in the week. Additional shower chances return as the weekend approaches.
Sunday: Showers and Non-Severe Thunderstorms
Expect scattered showers and a few thunderstorms on Sunday, with an initial round in the morning and another possible by late afternoon or evening. These storms should generally be non-severe, but small hail and gusty winds are possible in thunderstorm cores.
Highs will climb into the 70s. Warm and humid conditions can fuel rapid storm development in some spots.
ALERT DAYS: Monday and Tuesday
Monday and Tuesday have been designated ALERT DAYS as a deepening low-pressure system moves through the region, increasing the risk of severe weather. Warmer temperatures and higher humidity will provide the energy needed for strong winds, large hail, and heavy rainfall.
An isolated tornado cannot be entirely ruled out, though organization and coverage will depend on how the system evolves. People should be prepared for rapid changes and have a plan for shelter if a warning is issued.
- Severe thunderstorms capable of damaging winds and large hail
- Heavy rainfall that could lead to localized flooding, especially in low-lying areas
- Isolated tornado risk remains possible but uncertain
- Wind gusts up to about 35 mph are possible in stronger cells
High temperatures will push into the upper 70s to around 80°F on Monday and Tuesday, with humidity staying elevated. Plan outdoor activities accordingly and stay alert for weather alerts issued by your local station and apps.
Midweek Outlook: Wednesday to Thursday
By midweek, rain chances persist with scattered thunderstorms and continued breezy conditions. Rain may be heavy in some cells, and storms could redevelop into the afternoon and evening hours.
Skies will start to clear on Thursday, bringing a brief break with sunnier skies and lower rain chances. Isolated showers and storms could still pop up.
End of Week and Beyond: Friday, Saturday, and the Weekend
Isolated showers and storms return Friday and Saturday as another weather impulse passes. Weekend forecasts beyond next Saturday point to cooler temperatures and a potential rain/snow mix at times, signaling a transition to more unsettled but cooler weather.
Expect partly cloudy, breezy conditions to become more common the following week. Wind will continue to be a factor both day and night.
- Windy conditions with gusts that can reach 30–35 mph at times
- Chances for rain Saturday into Sunday, with cooler weekend temperatures
- Trend toward partly cloudy skies and quieter conditions early next week
Preparation and Safety Tips
As this period unfolds, staying informed is essential. Use local alerts and the station’s First Warn Weather app to receive real-time warnings and updates.
Here are practical actions you can take now:
- Secure outdoor objects that could blow around in gusty winds
- Check drains and gutters to prevent localized flooding in heavy rain events
- Plan travel with extra caution during anticipated severe weather windows
- Keep a weather kit and emergency supplies ready for both indoor and outdoor activities
- Remain aware of changes in the forecast, especially Monday and Tuesday
