The combination of a surface boundary and a surge of warm, moist air helped to initiate convective thunderstorms during the early afternoon hours of July 22nd. Widespread activity fired up across the area and persisted through the afternoon and early evening hours. Recent heavy rainfall and saturated ground across the forecast area set the stage for flash flooding. Thunderstorms moved slowly across the area with heavy rainfall. Some locations saw as much as 3 to 4 inches of rainfall in an 60 to 90 minutes. As areal coverage of the thunderstorms increased later that afternoon, a second round of thunderstorms hit some locations, resulting in rapid runoff and more flash flooding.
