Saturday, April 11, 2026 — Austin rolled out of bed into air that felt more like late May than early April, with muggy, overcast skies, temperatures parked in the upper 60s to around 70°F, and humidity hovering near 90 percent. Patchy fog early on is cutting visibility across neighborhood streets and along I-35 and MoPac, which could throw a wrench into the morning drive. By afternoon, the area is expected to heat into the low 80s as rain and thunderstorm chances ramp up.
Morning Fog And A Warm, Sticky Day
The fog should thin out by mid-morning, although a few light showers may sneak through before then. Clouds will hang tough for most of the day while a gentle southeast breeze develops, helping push highs to around 82°F. If you are planning to be outside this afternoon, keep in mind that scattered, fast-hitting downpours could bubble up with little warning and briefly drench any ongoing activities.
Saturday Night Line Could Produce Heavy Rain And Isolated Severe Weather
Later tonight, a shortwave trough is expected to shove a more organized line of storms into the southern Edwards Plateau and Hill Country late Saturday and into the overnight hours of Sunday, April 12. The National Weather Service Austin/San Antonio notes that heavy downpours and an isolated severe threat, including large hail and damaging wind, are on the table. Some guidance points to localized rainfall totals of 4 inches or more, mainly over Val Verde and Edwards counties. Stronger cells could kick up gusts to around 25 mph, with flash flooding and brief travel issues the main concern where storms stall or repeatedly track over the same spots.
Commute, Events And Flights
Between the early fog and a few spotty morning showers, drivers may find the Saturday commute slower than usual. Later in the day and into tonight, slow-moving downpours could lead to ponding on low-lying streets and slick conditions. At local airports, lower ceilings and reduced visibility are possible late tonight into early Sunday, which may tangle some flight schedules. Event organizers with outdoor plans should have a solid indoor backup ready to go. Build in extra travel time and steer clear of driving through standing water.
How To Prepare
Before storms arrive, it is a good idea to secure loose patio furniture and bring sensitive equipment indoors. Keep kids and pets inside if storms move into your neighborhood. Make sure wireless alerts are enabled on your phone and keep an eye on updates from the National Weather Service in case timing shifts or watches and warnings are issued. Having more than one way to get severe-weather information is especially important with an overnight event.
