Escalating Temperature Predictions for the Following Days
Wisconsin Weather Outlook for Later This Week
Wisconsin residents can expect a continuation of warm and humid conditions later in the week, with potential temperatures reaching the upper 80s to lower 90s in some areas [1][2]. This weather pattern is part of a broader trend of above-normal temperatures across the central U.S. for August 2025.
Heat and Humidity
Temperatures are forecasted to remain high, with the potential for some areas to reach near 90 degrees if sufficient sunshine occurs [3]. Humidity levels are expected to remain elevated, contributing to the overall warm and potentially oppressive conditions [1]. Overnight into early Wednesday morning, patchy ground and valley fog is expected to form, and fog should burn off quickly after sunrise. Locally dense spots of fog may develop in marshy or low-lying areas.
Potential Storms
There is a chance for scattered showers and thunderstorms, particularly during the afternoon as the atmosphere becomes more unstable due to the warm and moist air [3]. Recent severe storms and flash floods have been reported in the region, indicating a potential for similar weather events later in the week [5]. Wednesday will be a warm and partly sunny day, and dry and hot conditions are expected on Friday.
