A warm front moved through the mid-Atlantic on July 11. As it did so, a long fetch southwesterly flow developed. This brought warm and extremely humid air into the region, with moisture being drawn up from a developing tropical storm in the Gulf of Mexico. In the warm sector, widespread convection developed during the afternoon and evening. The primary impact was severe flash flooding in the tropical air mass. However, with a warm and unstable atmosphere in place and moderate shear thanks to the nearby front, some storms also became severe.
