7-Day Weather Forecast
Afternoon and evening storms are possible
The NWS expects mainly dry conditions Wednesday morning. A frontal boundary may then bring showers and thunderstorms into the northern forecast area during the afternoon and evening, with timing still uncertain.
Some storms could produce frequent lightning and gusty winds. An isolated stronger storm is possible, but the current outlook does not confirm a widespread severe-weather event or indicate that every community in the county will receive storms.
Heat and humidity may affect outdoor plans
Afternoon heat indices are expected to reach the low to mid-90s, with brief readings near 100 degrees possible in sunnier parts of Sheboygan County. Cloud cover and storm timing may create differences from one community to another.
People working outdoors, attending school sports, running errands or planning family activities should schedule hydration and cooling breaks. Organizers and participants should check updated forecasts before heading outside and move indoors when thunder is heard.
Additional storm chances continue Thursday and Friday
The county forecast calls for highs in the lower 80s Thursday and Friday, with additional chances for thunderstorms. Precipitation chances rise to about 80% Thursday night before remaining near 50% Friday, making late-week outdoor, commuting and boating plans worth checking again as forecasts are updated.
Residents should monitor the latest National Weather Service alerts for changes in storm timing or any newly issued watch, warning or advisory. Conditions can change quickly, especially near thunderstorms, even when no alert is active at the latest update.
