There's a 30 percent chance of thunderstorms hitting San Antonio Tuesday night into the morning hours, the NWS seven-day forecast states. Temperatures will drop to the 70s Tuesday night. That percentage drops Wednesday night to just 20 percent chance for rain.

San Antonio's weather forecast notes intermittent showers, thunderstorms, and increasing temperatures over the week.

A threat of flash flooding remains from "slow-moving heavy rains overnight and through the day on Monday," the National Weather Service warned.

Just 24 hours after devastating floods struck the Hill Country, more rain continues to fall including in San Antonio. The National Weather Service issued a flash flood warning for the northeast part of San Antonio.

Texas leads the country in flood deaths. Steep hills, shallow soils and a fault zone have made Hill Country, also called "flash flood alley," one of the state's most dangerous regions.
