Green Bay, Wis. – Drivers and beachgoers in northeast Wisconsin face a stormy stretch through early this week as thunderstorms roll across the region. Heavy rain, gusty winds, and the threat of rip currents on Lake Michigan beaches are raising safety concerns. Travelers should expect slick roads on I-43 and other major highways beginning Saturday night.
According to the National Weather Service in Green Bay, scattered thunderstorms are possible Saturday night into Sunday morning, with stronger cells producing small hail and gusty winds. The risk of severe storms is low, but localized flooding remains a concern. Kewaunee and Manitowoc counties are under heightened rip current risk, especially for swimmers and boaters late Saturday into Sunday.
Showers will linger Sunday into Monday, with thunderstorms likely by Monday afternoon. Rainfall totals could reach a half inch in localized areas, making for slow commutes and challenging travel across Brown, Outagamie, and Shawano counties. Power outages are not expected, but standing water may affect rural roads and low-lying neighborhoods.
Residents are urged to avoid swimming in Lake Michigan through Monday, delay unnecessary travel during heavy downpours, and keep storm drains clear of debris. Those driving late at night should watch for sudden ponding on highways.
The unsettled pattern tapers off by Tuesday, when partly cloudy skies return. Cooler and calmer conditions are expected midweek as fall weather begins to settle in across northeast Wisconsin.
Warnings may be updated if storms intensify or flooding worsens. Stay alert to local advisories and check the latest updates from the National Weather Service.
