An elongated surface trough slowly moved through south Texas on June 3rd, with ample Gulf moisture in place across the Lower Rio Grande Valley. This allowed for thunderstorms to develop, leading to heavy rain falling across portions of the Lower Rio Grande Valley, focused on Starr and Hidalgo County near the river. Eventually, enough rain fell to cause flash flooding and street flooding across portions of each county.
