San Antonio residents may see storm clouds mix with 95-degree heat Thursday, creating slick conditions on major roadways like I-35. Drivers should prepare for sudden downpours in the afternoon and evening, when thunderstorms could briefly reduce visibility and create hazards on busy commuter routes.
According to the National Weather Service in Austin/San Antonio, a 10 percent chance of storms develops after 1 p.m. Thursday. Though limited, any storm could drop heavy rain in a short time, bringing brief flooding to low-lying streets and highways. Southeast winds will keep air humid, making the heat feel even more oppressive.
Friday brings a return to clear skies, but the heat intensifies. Temperatures will climb to 96°F, with light winds offering little relief. Outdoor events and high school football games may feel uncomfortable under lingering September heat. Health officials urge residents to drink water frequently, limit outdoor exertion, and check on vulnerable neighbors.
The weekend stays dry, with highs near 95°F both Saturday and Sunday. East winds will ease conditions slightly, but sun exposure remains a concern for anyone outside for long stretches. By early next week, thunderstorm chances increase again, signaling a transition toward more unsettled fall weather.
Warnings could be issued if storm coverage expands, especially during peak commuting hours. Residents should monitor updates and plan accordingly.
