A severe thunderstorm bow echo brought severe winds to Harvey, Sedgwick, Butler and Greenwood counties.
During the evening of Monday April 7th, 2008 and the early morning hours of Tuesday, April 8th, thunderstorms developed and moved across much of Kansas, some of them becoming severe. A severe thunderstorm bow echo produced damaging straight line winds up to 90 - 100 MPH between midnight and 1am in Butler and Harvey counties. Image 1 and Image 2 are radar images of this small but powerful bow echo.Straight line damaging winds followed the I-35 turnpike in a line from 5 north of El Dorado to 1 north of Cassoday. The winds blew tractor trailers off of the turnpike, some with injuries. The wind damage also included numerous downed power lines, damage to numerous outbuildings, and some homes and manufactured homes. In addition a radar animation ( Image 3 ) shows how the event evolved and where the severe wind reports were located. Image 4 is a radar image taken just as the severe winds were occurring south of Burns in northern Butler County. The following images are of damage across Northern Butler County.
