Heavy Downpours Expected Today - Significant Rainfall Ahead
Weather Update for Southern Wisconsin
A Flood Watch is currently in effect for southern Wisconsin until 7:00 AM on Monday, as multiple rounds of showers and thunderstorms are expected to move through the region throughout the morning and afternoon hours on Sunday. Rainfall totals could climb quickly, making it important for those planning to get out on the roads to stay weather aware.
According to the available search results, southern Wisconsin experienced historic flooding on August 9-10, 2025, due to heavy thunderstorms with rain rates of 1-2 inches per hour. This was driven by a moist southwest inflow and a mesoscale convective vortex fueling downpours. However, the precise date and time when the current Flood Watch ends, as well as an extended forecast beyond August 18, 2025, are not provided in the results.
By Monday afternoon, southern Wisconsin will be mostly dry. Temperatures will be cooler due to cloud cover and storms moving through, with highs in the low 80s. The severe threat is down from yesterday, but the threat of flooding remains, particularly for the southernmost counties in the viewing area.
The rest of the work week is expected to be dry and calm overall, with chances of isolated storms/showers mid-week. By the end of the week, temperatures will heat back up into the mid and upper 80s.
For an up-to-date forecast after the Flood Watch ends, it's recommended to check the National Weather Service or local meteorological sources directly around the time the watch expires. The First Alert Day is due to the threat of flooding and flash flooding in southern Wisconsin.
As always, it's important to stay weather aware and follow any safety instructions issued by local authorities.
