Austin woke up under a thick blanket of fog and mist Tuesday, with temperatures near 58°F and visibility trimmed to about 2.5 miles. Translation: a slow, soggy start and a sky that will only grudgingly lift as rounds of showers and thunderstorms move through.

Rain and storms are likely well into the afternoon, with a high near 69°F and an 80–90% chance of precipitation. The National Weather Service Austin/San Antonio expects many spots to pick up three quarters to one inch of new rain, gusts up to 20 mph, and locally heavier totals where storms keep tracking over the same areas.

Morning Fog and Commute Impacts

Low clouds and fog are cutting visibility on surface streets and around Austin‑Bergstrom this morning, with very low ceilings likely to cause at least some slowdowns at the airport. Flyers may want to budget extra time for potential delays.

On the ground, transit riders should check CapMetro for any detours or schedule shifts and plan on a longer ride. Drivers are urged to take it easy at low‑water crossings, where water can collect quickly during heavier bursts of rain.

Where the Heaviest Rain May Fall

The eastern two‑thirds of the metro, including neighborhoods along and east of the I‑35 corridor, have the best shot at heavier, repeated downpours. That pattern could trigger brief urban flooding and fast‑rising creeks.

Forecasters flag those eastern counties as most at risk for higher rainfall totals, so residents east of I‑35 and anyone who regularly uses low‑lying crossings should keep an eye out for quickly changing water levels.

Looking Ahead

Showers should wind down by Wednesday afternoon, opening the door to a drier stretch late in the week. Highs are expected to climb into the mid‑80s on Thursday and the upper 80s by Friday, a quick warm‑up after today’s chill.
