Overview
|
Showers and thunderstorms streamed into southern Wisconsin ahead of and along a warm front during the evening of Wednesday, May 25, 2022. There was just enough turning of the winds (shear) and instability for a few storms to rotate. One storm strengthened and started rotating over Winnebago County in north central Illinois and tracked into southwest Rock County at 6:37 pm. The storm produced a tornado as it tracked northwest of Beloit. |
