San Antonio woke up muggy and gray Saturday, with temperatures sitting near 73°F at 5:20 a.m. CDT on April 4, 2026. A line of showers and thunderstorms is expected to sweep across the area through the day, with a daytime high near 78°F before readings slide into the upper 60s by mid to late afternoon. South-southwest winds of 5 to 15 mph will be on the breezy side, with gusts up to 25 mph likely during the afternoon commute.
What To Expect Today
Showers and thunderstorms are likely from mid-morning into the afternoon, with roughly an 80% chance of rain and new rainfall totals between one half and three quarters of an inch possible. Isolated heavier pockets could briefly push those amounts higher and trigger minor flooding in poor-drainage spots. Some storms may turn strong, with damaging winds and frequent lightning the primary concerns. By this evening, winds will swing around to the north-northeast, with gusts that could reach 30 mph. Drivers should be ready for hit-or-miss heavy downpours during the afternoon and evening commute, according to the National Weather Service Austin/San Antonio.
Evening Commute And Sunday Outlook
The main line of storms should gradually wind down overnight, although a few lingering showers could hang on into Sunday morning. Easter Sunday looks cooler and mostly cloudy, with highs near 65°F. Areas north and west of the city, along and north of I-10 and west of I-35, have the best odds for heavier rainfall totals and stronger wind gusts, so outdoor neighborhood events in those spots should be ready for soggy ground and unsettled skies.

Tips For Commuters
Pockets of heavy rain can quickly cut visibility and create standing water on low-lying streets, so never drive through flooded roadways and build in extra time for both the afternoon and evening drive. Tie down or bring in patio furniture and any loose outdoor items, keep an eye on radar through the day, and have a dry backup plan in place for Easter gatherings that were banking on some outdoor sunshine.
