Excessive Heat, Severe Thunderstoms and Flash Flooding: July 14th in Review

An oppressively hot, muggy July 14th gave way to strong to severe thunderstorms across the region.  Thunderstorms produced damaging winds across parts of north central and northeast Kansas, before gradually weakening as they moved to the southeast.  A few of these thunderstorms developed extreme rainfall rates as high as 3 inches per hour, which led to localized flash flooding during the early morning hours on Thursday.  The following is an overview of just what happened on this day of diverse weather extremes.
