A muggy, mostly clear start in Austin is not sticking around for long. Temperatures are already in the low 70s with dew points in the upper 60s, and a cold front moving in by midday is set to flip the script with showers and thunderstorms likely, including a few that could turn strong to severe.
What To Expect Today
Highs should peak near 82°F before slipping into the mid 70s once storms move through. Forecasters put the overall Saturday rain chance around 80 percent, with most spots picking up a quarter to a half inch of new rain and a few areas seeing heavier pockets. Some storms could produce large hail and damaging wind, including hail over 2 inches in a few cases, according to the National Weather Service Austin/San Antonio.
Timing And Impacts
The front is expected to push through the I‑35 corridor from late morning into early afternoon. That puts the highest storm risk around noon for Austin and by mid-afternoon for San Antonio. Translation for your schedule: the afternoon commute could feature sudden heavy downpours and gusty winds.
Where storms repeatedly track along the front, localized flash flooding and street ponding are possible. Avoid driving through standing water, and plan on slower travel on I‑35, MoPac, and other low-lying routes during heavier bursts of rain.
