On the evening of August 15, 2010 several thunderstorms rolled across western Kansas. Two storms in particular produced damaging winds in and near both McCracken and Larned. There were no injuries reported but both areas were surveyed to determine the nature of the winds.
At around 7:10 PM, a thunderstorm began to exhibit a "bow" appearance just as it reached Larned.
The southwest part of town had numerous large branches broken off from trees but the greatest damage occurred about 6 miles south of town where about a dozen power poles were snapped off. Center pivot sprinklers were rolled in the same area. Wind speeds are estimated at 80 to 90 MPH. See images below.
At about 8:15 PM, another storm pushed through McCracken. This appears to be a "microburst" event. A microburst is the result of rapidly decending air in a thunderstorm. It is evidenced by the "rear inflow notch" shown in the radar image below:
Most parts of McCracken had wind damage but the most intense damage was in the northeast part of town with damaged bleachers at the rodeo grounds as well as major damage to large trees. Wind speeds are estimated between 80 and 90 MPH. See images below:
