Austin woke up Monday, July 13, 2026, to muggy, partly cloudy skies, temperatures near 78°F, and dew points slogging through the mid-70s. The heat will build into the low 90s, and it will feel every bit of it, but scattered afternoon storms may briefly take the edge off.
Afternoon Storms And Heavy Humidity
Showers and thunderstorms are possible after 1 p.m. on Monday, July 13, with a high near 92°F and a heat index that could push around 102°F. Forecasters expect most daytime storms to be quick hitters with only light rain to start, according to the National Weather Service Austin/San Antonio.
Hoodline Update
Rising rain chances first popped on our radar in a July 10 update, and since then the forecast has shifted toward a much wetter setup for the week. See "sticky Austin sizzles" for the earlier outlook and cooling-center links.
Flooding Risk Through Thursday
The main concern runs from Monday night through Thursday night (July 13–16, 2026), when slow-moving, moisture-loaded storms could dump locally heavy rain and trigger pockets of flooding. Total rainfall of 2–6 inches is possible in parts of the region through Thursday, with isolated amounts up to 8 inches and a potential need for a Flood Watch. Residents in low-lying spots or dense urban areas should be ready for standing water and quick rises in creeks and drains, per the National Weather Service Austin/San Antonio.
Plan Ahead
Drivers should plan for slower evening commutes and watch for ponding on roads or small-stream flooding after storms move through. Do not try to drive through flooded roadways, keep an eye on updated forecasts and alerts, and check the City of Austin for cooling-center details and other emergency information.
