The showers encompassing most of Texas today will evolve into steadier rain across central and South Texas tonight. Rain will continue to pour down Friday, likely leading to flash flooding.
Urban and low-lying areas, as well as places along small streams, would be the first to become inundated with floodwater. Parts of interstates 10, 35 and 37 may be impacted. Remember, never put your life in danger by driving through a flooded roadway.
For South Texas, the threat Friday will shift from heavy rain to severe thunderstorms. Enough instability will be present that thunderstorms capable of producing damaging winds and isolated tornadoes ignite.
High pressure will return drier weather to Texas this weekend as the storm drops drenching rain on the East Coast.
