Milwaukee, Wisconsin – Eastern Wisconsin is expected to enjoy a prolonged stretch of cooler-than-normal weather from July 23 through July 27, as a broad Canadian air mass settles across the Great Lakes. The pattern is forecast to keep temperatures below seasonal averages while maintaining generally dry conditions, providing a welcome break from the heat and humidity that often define late July.
According to the National Oceanic and Atmospheric Administration’s Climate Prediction Center, in its 6-10 Day Outlook issued July 17, eastern Wisconsin is favored to experience below-normal temperatures throughout the July 23-27 period. The latest outlook also shows no enhanced precipitation signal across the region, indicating widespread or prolonged rainfall is not expected.
In Milwaukee, persistent winds off Lake Michigan are expected to reinforce the cooler pattern, keeping afternoon temperatures several degrees below what is typical for the final week of July. The lake breeze should also help suppress humidity, creating comfortable conditions for commuters, lakefront festivals, outdoor dining and recreational activities. Dry weather is expected to dominate, minimizing weather-related travel concerns.
Farther north, Green Bay is forecast to experience similarly pleasant conditions. Afternoon highs should remain below seasonal averages while overnight temperatures become noticeably cooler than recent weeks. Lower humidity and a lack of widespread rainfall should create favorable conditions for outdoor work, agriculture, tourism and summer events across northeastern Wisconsin.
The cooler air mass is expected to influence communities throughout eastern Wisconsin, including Kenosha, Racine, Sheboygan, Manitowoc, Appleton, Oshkosh, Fond du Lac and Door County. Communities along the Lake Michigan shoreline may experience the coolest afternoons due to persistent onshore winds, while inland areas should also remain comfortably below average with cool mornings and pleasant daytime conditions.
Although the Climate Prediction Center outlook does not specify the timing of any isolated weather disturbances, confidence continues to increase that eastern Wisconsin will remain in a cooler-than-normal pattern through July 27. Forecast updates from the National Weather Service will continue to refine daily temperature trends, but current guidance points toward an extended stretch of comfortable midsummer weather with little indication of widespread rainfall.
