A cold front is expected to push into San Antonio by late Wednesday afternoon to help eventually trigger more showers and lower temperatures.
The cold front fueled a line of severe thunderstorms on Wednesday morning that pushed west across the Hill Country, dropping some large hail. Egg-sized hail was reported near Llano and golf ball to baseball-sized hail was reported in northern Blanco and Gillespie counties.
Gillespie County Emergency Management Coordinator—Ashley Harris—said there were scattered reports of a few damaged vehicles and roofs in remote areas of far northeast Gillespie County, but no injuries.
Rain chances begin to increase on Thursday night for San Antonio and become more widespread across the city on Friday and Saturday. Up to half the area could see rain, but amounts were hard to predict.
Highs are expected to drop into the mid-70s on Thursday. Winds will shift out of the north, with gusts up to 25 miles per hour. Highs are expected to return to the 80s on Saturday and climb into the low 90s by Sunday.
Forecasters say Mother’s Day weekend is expected to be warmer, with only a slight chance of rain. Beyond the weekend, the broader outlook for May leans slightly wetter than average for San Antonio and the Hill Country, offering some relief for long-running drought conditions.
Recent rainfall has already helped boost water levels in the Edwards Aquifer, a primary source of drinking water for more than 2 million people. The aquifer stood at 639 feet this week, compared to 629 feet on the same date last year.
Even so, levels remain about 25 feet below the historical average for this time of year, and water restrictions in some communities are still in place.
Since the start of 2026, just over 11 inches of rain have been recorded at San Antonio International Airport, about 2 inches above average for this point in the year.
