The episode as NWS HGX wrote it up.
A series of upper level disturbances produced heavy rain and some severe weather across the southern portions of southeast Texas. Rainfall rates of one inch per hour for up to 6 hours at a time were recorded in Jackson, Matagorda, and Wharton counties. This led to widespread street flooding with some roads being washed out. Heavy rainfall in Galveston, Brazoria, Fort Bend, and southeastern Harris counties also led to street flooding, as well as water in some homes. The storms also produced three tornadoes causing minor damage and no injuries.
