San Antonio, Texas – A round of unstable weather is moving through the region today, bringing thunderstorms, gusty winds, and sudden downpours that are already impacting travel across key highways. The system began building earlier in the day as thick clouds covered the city, creating humid and heavy conditions that signal an active weather pattern.
According to the National Weather Service, scattered showers and thunderstorms are expected to increase throughout the day, with the strongest activity developing during the afternoon and evening hours. Wind gusts could reach between 30 to 35 mph in stronger storm cells, along with brief periods of intense rainfall.
What’s Happening Right Now
Storms are developing in pockets across San Antonio and surrounding areas, producing sudden bursts of rain and lightning. These fast-moving systems can quickly reduce visibility and create hazardous driving conditions within minutes.
Motorists traveling along major routes like I-35, Loop 410, and Highway 281 are already experiencing slick roads and intermittent slowdowns. In some low-lying areas, water is beginning to collect on roadways, increasing the risk of hydroplaning.
Impact on Travel and Daily Life
Drivers are being urged to stay cautious, especially during heavier rain bursts. Reduced visibility, combined with wet pavement, is making commutes more dangerous than usual. Officials recommend keeping headlights on, maintaining safe distances, and avoiding sudden lane changes.
Lightning activity may also intensify quickly in isolated storms, posing additional risks for anyone outdoors. Short but intense weather bursts mean conditions can shift rapidly from calm to severe.
What to Expect Tonight
Storm activity is expected to continue into the evening, with multiple waves of rainfall moving through the area. While not constant, these repeated rounds could lead to accumulating rainfall and ongoing travel disruptions.
Looking Ahead: Short Break, Then More Storms
Sunday is expected to bring a temporary break from the more intense weather, though clouds will remain and a slight chance of rain will persist. Temperatures will cool into the upper 60s, offering a brief period of calmer conditions.
However, the pattern doesn’t end there. Storm chances increase again on Monday, with a higher likelihood of showers and thunderstorms returning. This unsettled weather could extend into Tuesday, continuing to affect commutes and outdoor plans.
By midweek, conditions begin to stabilize. Warmer temperatures are expected to return, with highs climbing into the low 80s and fewer storm interruptions by Wednesday and Thursday.
