Hail as big as grapefruits has left behind broken windows and other storm damage in parts of South Texas.
The National Weather Service says the San Antonio area has a chance for additional thunderstorms through Wednesday.
Hail fell over much of north Bexar County on Tuesday night, with forecasters saying an area near Helotes recorded hail the size of grapefruits. San Antonio International Airport received more than an inch of rain.
Authorities had no immediate reports of anyone hurt. Bexar County sheriff's spokesman James Keith says at least nine law enforcement vehicles sustained hail damage.
Scattered street flooding was reported in San Antonio.
Forecasters say the Houston area also faced lingering thunderstorms through Wednesday and some high-water road issues following overnight rain.
