San Antonio starts Wednesday under cloudy skies, but the heat is set to return quickly. Temperatures will climb to around 93 degrees this afternoon, with the heat index reaching as high as 102. A few showers or thunderstorms could pop up after 4 p.m., but most of the city should stay dry.
Heat Peaks This Afternoon
The National Weather Service says south-southeast winds will run 10 to 15 mph, with gusts reaching 25 mph. Rain chances are about 20%, meaning a brief downpour is possible but far from a citywide washout. Partly cloudy skies and lows of 70 degrees at San Antonio International Airport and 71 at Stinson Municipal Airport are expected.
Thursday will bring another mostly sunny and hot day, with a high near 90 and only a small chance of rain. The setup changes late Thursday night as a cold front approaches the region, although the best rain chances for the San Antonio area remain limited to a few sprinkles or light showers, according to the National Weather Service.
Gusty Winds Lead Into A Cooler Weekend
Friday will feel dramatically different after the front moves through early in the day. Highs should top out near 77 degrees, while north-northeast winds of 15 to 25 mph could gust up to 40 mph. Skies are forecast to be mostly sunny.
The cooler pattern sticks around through the weekend, with a low as low as 60 Friday night. Sunday should be pleasantly cool, while temperatures begin climbing again Monday and Tuesday. Tuesday could bring another slight chance of afternoon showers and thunderstorms, but the immediate headline is clear: one more hot stretch, then a sharp autumn-style reset.
