...Straight Line Wind Damage Hits During the Overnight Hours - June 11, 2009...
Yet another severe thunderstorm pummeled portions of extreme Northeastern Kansas as well as locations south of St. Joseph, MO during the overnight hours of the 10th. This storm developed ahead of a weak mid-level wave which was crossing the lower Missouri River Valley after midnight. As the storm developed across western portions of Atchison County in Kansas and then began to collapse across eastern portions of the county, it produced strong wind damage near the city of Atchison and further east towards Rushville and DeKalb. Earlier today, a NWS storm survey team travelled to the impacted areas, reporting all damage which occurred was due to straight line winds and microburst winds greater than 60 mph with other damage created by large damaging hail. These winds were strong enough to overturn a camper trailer just east of the city of Atchison, KS injuring the occupants of the trailer. This storm also produced damage to a grain bin, along with fairly widespread flattening of brush, grass, and crops in the area.
The following are images of the estimated storm track, along with the radar indicated path of the strongest winds associated with this storm. There is likely additional minor agricultural damage from this storm (white shaded area) not indicated on these maps.
