THIS WEEKEND
Rain chances are essentially finished for San Antonio through the weekend, with mostly dry conditions expected area-wide. A small and very brief pop-up shower could develop near the coast and attempt to travel farther inland. Any activity that pops is going to provide insignificant rainfall and cooling.
Expect plenty of sunshine and hot afternoon temperatures both Saturday and Sunday. Highs will climb into the upper 90s across much of the area, with some locations approaching the 100-degree mark.

While temperatures will be hot, the good news is that most communities should remain just shy of the triple-digit heat that has dominated much of August.
EXTENDED FORECAST
The extended forecast offers a welcome change from recent weeks, with temperatures expected to stay below 100 degrees for much of the upcoming week. Isolated showers and thunderstorms, driven by the afternoon sea breeze, may develop along the Coastal Plains. Besides this, most of San Antonio and South Central Texas can expect a stretch of hot and mainly dry weather.
