7-Day Weather Forecast
The Milwaukee/Sullivan office issued a Hazardous Weather Outlook at 6:11 a.m. CDT Tuesday, listing Sheboygan County among the areas that could be affected.

Storm timing and county forecast
The official Sheboygan County forecast, updated at 7:31 a.m. CDT, calls for patchy morning fog, mostly cloudy conditions, a 50 percent chance of showers and thunderstorms, and a high near 80 degrees.
The strongest storm potential is expected from mid-morning through early afternoon. The outlook describes possible conditions, not a guarantee that severe weather will affect every part of Sheboygan County.
What residents and commuters should do
Residents should continue monitoring National Weather Service updates in case the outlook changes or a watch or warning is issued. Before storms develop, secure loose outdoor items and make a plan for moving inside if thunder is heard.
Commuters and delivery drivers should allow extra travel time, especially if fog or heavy rain reduces visibility. Never drive through a flooded roadway; water depth and road conditions can be difficult to judge.
Families planning outdoor activities, local businesses, and anyone traveling through the county should check conditions before leaving and be ready for a change in plans during the higher-risk window.
If the National Weather Service issues a warning, people in the affected area should follow that alert immediately and move to a safe location.
