San Antonio, Texas – Stormy skies and widespread haze are poised to hit San Antonio this Tuesday afternoon, disrupting travel and outdoor plans just ahead of the July 4th holiday. Residents across Bexar County should brace for scattered thunderstorms after 4 p.m., especially along major routes like I-10, Loop 410, and I-35.
According to the National Weather Service in Austin/San Antonio, there’s a 30% chance of thunderstorms Tuesday afternoon, rising slightly into the evening. Southeast winds up to 10 mph will bring in the moisture. Haze is expected to linger through sunset, potentially lowering visibility for commuters and air travelers alike.
Localized downpours could slow evening commutes and create slick road conditions. Those heading to fireworks stands, cookouts, or events are urged to monitor live radar and avoid flooded intersections. Winds could gust as high as 20 mph later this week.
