Large hail, heavy rain in San Antonio forecast within hours A severe weather event is expected to impact San Antonio and surrounding areas, including Austin, Texas, on Saturday, March 7, 2026. The National Weather Service (NWS) has issued warnings about large hail, heavy rainfall, and damaging wind gusts, urging residents to prepare for potentially hazardous conditions. The storm system is anticipated to bring significant disruptions, with the most intense activity likely occurring in the late morning and early afternoon. Meteorologists at the NWS explained that a cold front will move into the Edwards Plateau and Hill Country late in the morning, spreading into the broader region by the evening. This front is expected to increase the likelihood of showers and thunderstorms, with the highest probability of severe weather occurring before 9 a.m. and continuing through midday. The NWS has classified the risk of severe storms as level two out of five, indicating a moderate threat. These storms could persist intermittently through the morning of Sunday, March 8, with localized heavy downpours affecting some counties. The forecast highlights a 75 to 85 percent chance of rainfall exceeding one inch in the Hill Country, I-35 Corridor, and Coastal Plains. San Antonio is currently at 83 percent, while Austin sits at 85 percent. The risk increases further west, with Kerrville at 88 percent and Fredericksburg at 86 percent. The NWS warns that some storms could produce hailstones up to two inches in diameter, while wind gusts may reach up to 20 mph during both daylight hours and after sunset. In addition to hail and strong winds, the primary hazards include minor flooding, which could result from the heavy rainfall. The NWS advises residents to avoid outdoor activities and remain indoors to minimize risks.#national_weather_service #san_antonio #austin #edwards_plateau #hill_country
