San Antonio's Friday forecast calls for a mostly sunny afternoon with temperatures near 95. The weekend offers little relief, with light winds, warm nights and a stubborn summer feel across the city.

Sunny Weekend Keeps Summer In Charge

Friday night will turn partly cloudy with a low near 75, followed by a partly sunny Saturday topping out around 94. Sunday could be even warmer at 96, while Monday remains mostly sunny with another high near 96. Isolated showers and thunderstorms are also possible Sunday and Monday.

East to southeast winds should generally stay light through the weekend, though Monday night could bring gusts up to 20 mph. The National Weather Service Austin/San Antonio office has no watches, warnings or advisories posted for the area.

Rain Chances Build Tuesday

Rain chances continue Tuesday, September 29, with a chance of showers and thunderstorms. Southeast winds could gust to 20 mph.

Wednesday brings the best odds for rain in the near-term forecast, with a 50% chance of showers and thunderstorms and a high near 91. Thursday stays unsettled with a 40% chance of rain and storms, while the high falls to about 88.

A Cooler Pattern May Finally Arrive

Forecasters say a Pacific cold front could bring more widespread rain next week, followed by cooler, drier air. The timing remains uncertain, but the change would mark a noticeable break from the heat that has dominated San Antonio weather coverage this month, including Hoodline's previous forecast.
