Green Bay, Wisconsin — A brief round of showers could impact northeast Wisconsin early Sunday, with light rain between 6 a.m. and 10 a.m. creating slick roads and reduced visibility in Green Bay, Appleton, Oshkosh, Manitowoc and Sheboygan.
According to the National Weather Service in Green Bay, rain chances remain limited Sunday morning before conditions improve, followed by a more organized round of rain and a few thunderstorms developing Monday afternoon across the region.
This is part of a broader system bringing a short warmup into Monday before a cold front moves through, triggering rain and cooler air by Tuesday.
Light rain Sunday may dampen roadways along I-43 and US-41, especially on bridges and low-lying stretches where moisture lingers after a frosty start. By Monday afternoon, steadier rain could lead to ponding on urban roads and underpasses, particularly in Appleton and Oshkosh, where drainage is slower during heavier bursts between 4 p.m. and 7 p.m.
Drivers should slow on wet roads and watch for changing conditions during both morning showers and Monday’s commute, while residents should monitor updates for potential thunderstorms.
The next significant impact window will occur between 4 p.m. and 7 p.m. Monday, when rain and possible storms may disrupt travel across northeast Wisconsin.
