The back door front had mostly washed out, but southwesterly flow aloft on the west side of the Bermuda High kept the area quite humid. A cold front was approaching from the Mississippi and Ohio Valleys, and heavy convective rain was training along southwest-to-northeast oriented bands, producing significant flash flooding.
