Green Bay, WI – Rain and thunderstorms will begin cycling into Wisconsin by Friday and continue into next week, setting up a prolonged stretch of wet weather that could lead to rising rivers and localized flooding concerns by early next week.
Conditions will stay relatively quiet through early Friday, but clouds will increase before scattered showers arrive late Saturday. By Sunday, storm chances expand across northeast Wisconsin, with temperatures climbing into the 70s, adding fuel for more active weather.
According to the National Weather Service in Green Bay, the most impactful period begins Monday into Tuesday, when repeated rounds of moderate to heavy rain could develop alongside thunderstorms. Some storms may strengthen during this window, increasing the risk of heavier downpours and brief gusty winds.
Cities including Green Bay, Appleton, Oshkosh, and Marinette could see multiple rounds of rain, with water beginning to pool on roads during heavier bursts. Low-lying areas and poor drainage zones may be especially vulnerable if rainfall totals build over consecutive days.
The concern extends beyond daily rain chances. Rivers and streams across the region may begin to rise as rainfall accumulates through the early part of next week. Areas prone to flooding should closely monitor conditions, especially if storms repeatedly track over the same areas.
Residents are encouraged to stay weather-aware, particularly heading into Monday and Tuesday when impacts are expected to peak. Avoid driving through water-covered roads and ensure you have multiple ways to receive alerts if warnings are issued.
This unsettled pattern is expected to persist through much of next week, with additional rain chances continuing and the potential for further advisories as confidence in rainfall totals increases.
