San Antonio, Texas – Spring heat is back in full force across South Central Texas, with San Antonio residents looking at five straight days of 87°F to 91°F highs starting Saturday. Gusty winds and an increasing chance of thunderstorms could impact travel, especially along I-35 through Tuesday.
According to the National Weather Service, Saturday will bring mostly cloudy skies early, then sunshine by afternoon with a high near 87°F. Winds will pick up from the southeast, gusting up to 20 mph. Sunday and Monday will both hit 91°F, with even stronger wind gusts—up to 25 mph—making outdoor plans and driving conditions more difficult, particularly for high-profile vehicles.
Although the weekend remains mostly dry, the pattern shifts on Tuesday as scattered showers and thunderstorms return after 1 p.m. While the current rain chance stands at 20%, Wednesday carries a 60% probability of storms, potentially disrupting commutes and afternoon activities.
Travelers along I-35 should prepare for reduced visibility and slick road conditions during heavier downpours midweek. Consider rescheduling outdoor activities and secure loose objects as wind speeds increase.
