San Antonio drivers may face slick conditions Sunday afternoon as thunderstorms threaten the I-35 corridor, paired with sweltering late-August heat.
According to the National Weather Service, a 30 percent chance of showers and thunderstorms develops after 1 p.m. Sunday. Temperatures will climb near 96°F, with heat and humidity pushing the feel-like temperature even higher. Rain could briefly cool the region, but sudden downpours may create hazardous travel, especially along major roadways like Loop 1604 and U.S. 281.
The storms come after a hot Saturday that topped out near 94°F. Sunday night will bring calmer skies, though muggy lows will hover in the mid-70s. Conditions remain unstable into Monday, when another round of storms could track across Bexar County and surrounding communities.
Travelers should use caution if caught in storms, as lightning and brief gusty winds may reduce visibility. Outdoor events may need contingency plans Sunday afternoon into the evening. Officials advise residents to limit time outdoors during peak heat hours and stay hydrated.
The unsettled pattern lingers through midweek, with storm chances returning Tuesday and Wednesday. By Friday, San Antonio should see drier skies, but temperatures could approach the upper 90s again.
