San Antonio woke to muggy, partly cloudy skies Saturday, March 7, 2026, with temperatures in the mid‑70s and humidity thick enough to feel like a wet blanket. A cold front sliding into the region is set to wring that moisture out of the air, turning it into a round of showers and thunderstorms that could tangle up the midday commute. If you have errands or outdoor plans, be ready for weather‑related interruptions during the midday and evening hours.
Afternoon And Evening Showers
Showers and thunderstorms are likely Saturday, with a chance of rain before 9 a.m., then a higher probability through the afternoon and evening. Highs will climb to near 83°F before slipping back into the upper 70s. Expect east‑southeast winds at 5 to 10 mph with gusts up to about 20 mph this afternoon, shifting to north‑northeast tonight with gusts around 25 mph. Much of the afternoon rain should stay on the lighter side, under a tenth of an inch, but heavier bands tonight could drop a quarter to a half inch locally, with isolated higher totals possible, according to the National Weather Service Austin/San Antonio.
Severe Storm Risk
Forecasters note that a few storms could grow strong to marginally severe, packing large hail and damaging straight‑line winds in the most intense cells. The greatest hail threat will sit close to and east of the I‑35 corridor, and training storms could lead to brief but intense downpours and small‑area flooding. Anyone at outdoor events should have a shelter plan ready and keep a close eye on sudden changes in wind or visibility.
What This Means For Your Plans
Wet roads and gusty crosswinds will likely slow the midday and evening commutes, so drivers should build in extra time and steer clear of standing water. Event organizers and restaurants with outdoor seating should be prepared to move people under cover if storms flare up.
