Tornado in Riley County, Kansas

A storm chaser showed video of what appeared to be a brief funnel near the ground in open country north of Interstate 70. Any actual contact with the ground was brief and no damage was noted or reported. The feature lost its organization as it moved south over I-70.

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.
