This afternoon, Southeast Wisconsin is experiencing a series of showers and thunderstorms as a cold front approaches from the west. The National Weather Service indicates that while the scattered storms may produce brief heavy rainfall, severe weather is not expected.

As we transition into tonight, more significant storm activity is likely. Rainfall amounts could range from 0.1 to 0.5 inches across much of the area, with regions west of I-39 potentially seeing higher totals up to 1-2 inches in some spots. While the threat of widespread flooding is low, be aware of localized ponding in areas where storms train over the same places.

Swim Risk

It’s important to stay cautious if you’re planning outdoor activities, as storms could bring flashes of lightning and brief downpours. Current forecasts indicate a moderate swim risk at the beaches in Ozaukee and Sheboygan Counties due to increasing wave heights. If you’re heading that way, avoid breakwaters and piers for your safety. A Beach Hazards Statement is in effect for areas farther north.

“Moderate swimming risk continues through mid-evening (~9 PM) at Sheboygan and Ozaukee County beaches.”

Thunderstorms Ending Wednesday

Moving into Wednesday, the cold front will push through the area, bringing an end to the stormy weather by the afternoon. Once the front passes, high pressure is expected to settle in, resulting in warmer temperatures and low humidity through the end of the work week. Keep an eye out, though, as another round of showers and thunderstorms is forecasted for Friday night into Saturday.

Summary

For Southeast Wisconsin, expect an afternoon and evening filled with showers and thunderstorms. With pleasant weather on the horizon, be sure to stay informed about the changing conditions.
