Weather Advisory in Effect
As we enjoy another warm afternoon in Northeast Wisconsin, an Air Quality Advisory is currently in effect for portions of the region. This advisory will remain until 11 PM this evening, so please take precautions if you are sensitive to air quality issues.
Showers and Storms are on the Way
Scattered showers and thunderstorms are developing across western Wisconsin and are expected to move into north-central and central areas between 3 PM and 6 PM today. The storms will then spread eastward toward Northeast Wisconsin shortly after midnight. While there is some uncertainty in how much precipitation will impact east-central Wisconsin, be prepared for potential heavy rain, gusty winds, and small hail.
“Some of the storms could become strong or severe with damaging winds and large hail.”
Friday Predictions
On Friday, another round of showers and thunderstorms is anticipated in the afternoon and evening as a weak cold front moves through. The greatest threat for stronger storms with damaging winds and hail will occur between 4 PM and 10 PM. It is crucial to monitor the latest updates as conditions develop, given the variability in forecast models.
Looking Ahead: Increasing Heat
As we look towards next week, expect a rise in temperatures and humidity. By late next week, many locations may experience heat index values climbing into the 90s, and a few locations could even reach triple-digit readings. This intense heat may lead to road buckling, so be cautious if you are traveling.
