June 21, 2006: Straight-line wind in Dodge, Walworth and Waukesha Counties

Numerous thunderstorms developed during the early morning hours of June 21st, producing mainly damaging straightline winds. Trees and power lines were reported down across many areas of south-central and southeast Wisconsin. A funnel cloud was also reported in Dane County and a hail report was received from Rock County. Synoptically, thunderstorms developed along a warm front that extended from northeast Iowa, into southern Wisconsin and across Lake Michigan into Lower Michigan. A layer of drier air aloft contributed to the cause for wind damaging thunderstorms.
