San Antonio rolled into Tuesday, April 14, 2026, under cloudy, muggy skies and a mild 72°F start, with a south-southeast breeze already in play. Afternoon highs are set to climb into the mid-80s, and sticky overnight lows should hang near 70°F. By later today, gusts around 20 to 25 mph could be enough to shuffle lawn furniture and tug at backyard canopies.
Afternoon Winds And Isolated Storms
Most of the metro is expected to stay dry through the afternoon, but isolated storms firing up over West Texas could clip the southern Edwards Plateau, including Edwards, Kinney and Val Verde counties, along with parts of the Rio Grande Plains this evening between about 5 to 10 p.m. A few of those cells may turn strong to severe, with large hail, damaging wind gusts and a brief tornado possible in isolated spots. Forecasters at the National Weather Service are urging residents in western Bexar County and neighboring counties to keep an eye on conditions if they have evening plans.
Midweek Warmth, Then A Weekend Shift
Wednesday looks like another muggy one, with a chance of afternoon showers and thunderstorms and highs again near 85°F, while Thursday and Friday are on track to warm into the upper 80s to around 90°F. Humidity will stay elevated, which means nights will be slow to cool off. For background on the developing pattern, see our earlier piece, muggy skies put San Antonio on storm watch.
Weekend Front Could Bring Cooler Weather
A stronger front is expected to move through on Saturday, with showers and thunderstorms possible ahead of the boundary and much cooler, drier air arriving Sunday into Monday. Highs are likely to drop into the 60s and 70s, and overnight lows could fall into the 50s after the front passes, especially north of I-10. The National Weather Service has the latest timing and outlook for the weekend change.
What to do: secure loose outdoor items before those gusts kick up, keep an umbrella handy for late-day plans in the Hill Country, and check for updates if you have outdoor events Saturday night. If storms ramp up in severity, move indoors and avoid driving through standing water.
