Early Morning Severe Weather Hits the Region - June 9, 2009

...Thunderstorms Roll Across the Area Early on the 9th...

An early morning complex of thunderstorms rolled across portions of eastern Kansas and central Missouri during the morning hours of June 9th. These thunderstorms developed quickly by mid-morning lifting northeastward while producing large hail in locations from Belton to Butler and Clinton. A radar image below depicts this first round of thunderstorms which produced large hail. An additional area of thunderstorms developed over central Kansas and began to surge southeast towards the Kansas City metropolitan areas by early afternoon. As shown in the second radar image, several of these storms took on a "bowing" shape, often an indication of strong to even severe outflow winds. These thunderstorms raced over the same areas as were hit in the morning, producing tree damage with estimated winds at 60 mph.
