Early Tuesday Update: Severe thunderstorm watch expires as showers and storms wind down
Updated: 3:15 a.m. March 31, 2026
The Severe Thunderstorm Watch issued Monday evening has been allowed to expire. While we did not see any severe thunderstorm warnings locally, we did have a few strong thunderstorms especially in Sheboygan/ Fond du Lac County and Racine/Kenosha Counties where some hail was reported.
Most of the stronger thunderstorms early this morning have stayed in northern Illinois. An area of rain and embedded storms will likely roll into areas along and south of I-94 from now until 6 AM. An isolated stronger storm may be possible but most storms should stay below severe limits. As the showers move through some gusty winds are possible, maybe even higher than 50 mph at times.
Another round of scattered thunderstorms are likely during the day on Tuesday. Look for an updated new CBS 58 Weather Blog later Tuesday morning for the details on that.

So far, no warnings have been issued for our area. But, a good chunk of southern Wisconsin is under a Severe Thunderstorm Watch. It runs until 3am.
As of now we do have one batch of storms moving east across much of Racine and parts of Kenosha counties. And there's another isolated storm in the far northeast part of Fond du Lac and western Sheboygan counties. These will be moving quickly to the east and out of the area in the next 20 minutes or so. Once this activity moves on, there's not much to our west at the moment. We will continue to monitor radar trends overnight and provide updates as needed.

We are still on track for severe storms tonight. They should be mostly confined to where a boundary sets up shop tonight. This looks to favor southern parts of the area.
This is what our latest model is suggesting for storms around 11pm. This is the best start time for the Milwaukee area, but again places south of I-(4 have the best chance for storms tonight.

The Storm Prediction Center has shifted the Level 2 Slight Risk a bit to the west now for storms Monday night into early Tuesday morning. The risk now mostly includes western counties and parts of western Waukesha Counties. Large hail is still the primary threat. The rest of the forecast including the timing of storms outline below remains on track.

The warm up started Sunday with highs reaching the low 60s. More 60s are expected for highs both Monday and Tuesday. Each day has a lake breeze so highs lakeside could even reach the 70s Monday and upper 60s on Tuesday. Everyone cools down Wednesday into the upper 30s for highs after a fierce cold front drops temps Tuesday night. Then rebound by the end of the week.
Most of Monday during the day stays with a mostly sunny sky or a mix of sun and clouds. The chance for storms will return late Monday evening through early Tuesday.
Any storms Monday night will be one of those situations where the chance for storms may be in question, but any storms that do form could be strong. Most of southeast Wisconsin is under a Level 2 Slight Risk (yellow) for severe weather.
The biggest threat with any strong storms Monday night into Tuesday morning would be large hail, potentially up to 2" in diameter.
More scattered showers are possible Tuesday morning with another round of storms returning in the afternoon through the evening hours. Once again some strong thunderstorms will be possible with all of southeast Wisconsin under a Level 1 Marginal Risk. Small hail and gusty winds would be the main threats.
