Convection formed over the northern Mexican mountains during the afternoon and evening of August 20 beneath an upper level trough over the southern plains. This convection eventually formed into a mesoscale convective system as a low level jet developed overnight. The MCS produced heavy rain as it moved into a tropical airmass over South Central Texas. The MCS dissipated, and then convection redeveloped as a cold front moved through the region on August 21 and produced more heavy rain.
