| Episode Narrative | A residual surface boundary that extended from eastern Iowa across northern Illinois was the focus for thunderstorm development as a moderate southwest 850 mb jet pushed it north as a warm front. Upper divergence from the right entrance region of an upper jet maxmum provided additional lift. Moderate deep layer wind shear produced sustained updrafts to form thunderstorm clusters that evolved into short line segments as they reached southern Wisconsin. The severe thunderstorm lines produced damaging wind gusts in a swath from Iowa County along and either side of the I-94 corridor to Milwaukee and Ozaukee counties. |
| Event Narrative | Law enforcement officers reported numerous trees and power lines downed in a 5-mile wide swath from west of Mequon to Port Washington from damaging severe thunderstorm wind gusts estimated at 56 knots (65 mph). |
