July 24, 2012: Straight-line wind in Walworth County
What the National Weather Service recorded
A strengthening low-level jet pushed over a stalled frontal boundary over southern Wisconsin with a very warm, moist and unstable air mass under very steep lapse rates provided the focus for strong to severe thunderstorms during the pre-dawn hours of July 24th. The severe thunderstorms produced a discontinous swath of damaging wind gusts that downed trees and power lines from near Darlington in Lafayette County, eastward across Green and Rock counties to Lake Geneva in Walworth County.
