A slow moving storm system over the northern Gulf Coast will continue periods of showers and thunderstorms over much of the Southeast U.S. through this weekend. The risk for heavy to excessive rainfall increases on Sunday as a surge of increased moisture moves over parts of northern Florida into southern Georgia. Read More >
Overview
In the afternoon and evening hours of Monday, September 19th, a line of thunderstorms moved across southern Wisconsin. Most of the storms only produced small hail, gusty winds, and heavy rain, but a few storms did produce severe weather. The strongest storm of the afternoon began near La Crosse in western Wisconsin and moved west southwest towards Madison. Once the storm arrived in the Middleton and Madison areas, several people reported hail in excess of 1 inch, and in a few instances, hail greater than 2 inches. The largest hail stones reported were 2.25 inches.

Storm Reports
Here are maps of the official severe weather reports across southern Wisconsin. Notice how the bulk of these reports came from the Middleton and Madison areas. This is likely due to the fact that there are more people in these areas. We are nearly certain that there were more reports outside of Middleton and Madison, and if you have any other reports place pass them along. We are especially looking for reports near Mazomanie, Cross Plains, and Stoughton.
