The thermal ridge continued to keep much of the central CONUS hot in early August, and on the evening of August 6th a front sunk south into northern Iowa. This provided the impetus for convective development that for the most part remained sub severe other than a gust in Kossuth County. After the initial cluster of thunderstorms passed, additional storms developed along the front and trained across northern Iowa overnight. This resulted in a pocket of heavy rain with over six inches reported in a few locations. Despite the heavy rain, no flash flooding was reported, due at least in part to ongoing drought in the area.
