EF1 tornado in Marshall County, Kansas

Storm survey and storm chaser video and photos revealed a brief tornado just northeast of Marysville. This tornado did damage to a barn and power pole short path. The damage to a lumber shop south of highway 36 appears to have been related to a possible RFD surge south (straight line winds) and not this tornado.

One large high precipitation supercell formed near the Nebraska Kansas border and tracked south during the evening of June 11th producing widespread damaging straight line winds of 80-110 mph along with several small tornadoes. The majority of property damage was done by straight line winds within what was the rear flank downdraft of the supercell which was moving south southwest. The widespread destructive winds within the RFD often preceded any smaller vortex with the small tornadoes making damage from tornadoes difficult to distinguish from the downbursts and microbursts within the larger RFD swath. We believe there were at least 5 tornadoes that evening all EF0 or EF1. Ironically, the magnitude of damage from straight line winds in spots exceeded that of the smaller tornadoes.
