Severe Thunderstorm Watch Issued for Southeast Wisconsin

As severe weather hangs over southeast Wisconsin, the National Weather Service (NWS) has issued a severe thunderstorm watch for several counties in the region, effective until 3 a.m. on March 31, 2026. This watch includes Milwaukee, Waukesha, Jefferson, Walworth, Kenosha, and Racine counties, marking a period of heightened alert for local residents.

The primary concern associated with this watch is the potential for hail, which could reach sizes up to a quarter. According to WeatherWatch 12 Chief Meteorologist Mark Baden, the storms are currently moving rapidly at speeds of nearly 50 mph, creating conditions conducive to severe weather.

"A severe thunderstorm watch means that conditions are favorable for the development of severe thunderstorms in and close to the watch area," explained the NWS. The definition of a severe thunderstorm includes those that produce hail of one inch or larger in diameter and/or winds that exceed 58 mph. So far, no warnings have been issued, which is a positive sign for the region, as it indicates that the most severe weather has so far remained to the south, in Illinois.

Residents in the watch area should remain vigilant as the storms approach. The NWS advises people to review severe thunderstorm safety rules and be prepared to seek shelter if threatening weather approaches. It's important to note that a watch does not mean that severe weather is imminent, but rather that conditions are ripe for such events to occur.

As the evening progresses, additional showers and thunderstorms are expected to develop throughout the night and into the morning hours of March 31. The forecast suggests that southeast Wisconsin will experience a mix of rain and thunderstorms, with temperatures significantly dropping after a cold front passes through. Areas south of I-94 are particularly at risk for larger hail and stronger storms.

Looking ahead, the weather pattern will continue to shift. Tomorrow, March 31, is expected to see a mix of hit-and-miss showers and thunderstorms, with the potential for more severe weather in the evening. Meteorologists are keeping a close eye on the freezing line, as there could be a risk of freezing rain in the northern counties of Wisconsin.

"We're looking at a busy week ahead, with rain expected at various points on Wednesday, Thursday, and Saturday," noted Baden. He emphasized the importance of being prepared for changing weather conditions, especially as temperatures drop significantly. For example, temperatures in Sheboygan are expected to remain quite cool, contrasting sharply with warmer areas to the south.

In terms of rainfall, the NWS predicts that the area could receive between 2 to 3 inches of rain over the course of the week, with the heaviest downpours occurring during thunderstorms. This amount of rain could lead to localized flooding, especially in low-lying areas.

As residents prepare for the potential storms, they are reminded to stay tuned to local weather updates and be ready to take action if warnings are issued. The severe thunderstorm watch is just one indication of the active weather pattern expected in the coming days. With meteorologists predicting another round of storms on Wednesday night, it’s clear that the weather will remain a topic of concern for southeast Wisconsin in the immediate future.

In light of these developments, community members are encouraged to keep emergency kits ready, secure outdoor items that could be blown away by strong winds, and remain informed about the latest weather updates from reliable sources.

For now, the focus remains on the immediate threat posed by the severe thunderstorm watch, with residents advised to take it seriously and prepare accordingly. As the storms develop, it will be important to monitor conditions closely and respond appropriately to any warnings that may arise.
