Austin, Texas — Dry and cooler conditions will keep travel conditions stable across central Texas through the weekend, but a warming trend into the upper 80s and low 90s will set the stage for returning rain and storm impacts beginning Wednesday afternoon in Austin, San Antonio, New Braunfels, San Marcos and Del Rio.
According to the National Weather Service in Austin-San Antonio, rain chances will increase to 20 to 30 percent between 3 p.m. and 8 p.m. Wednesday, marking the first round of scattered showers and thunderstorms after several dry days.
This is part of a broader system shifting from a quiet weekend pattern into a more active midweek setup, as increasing moisture and daytime heating fuel storm development.
Storms may produce brief downpours capable of quickly creating slick roads and water pooling on low-lying streets and underpasses, especially in urban corridors along I-35 and I-10. Reduced visibility during heavier rain could slow evening commutes, particularly in Austin and San Antonio where traffic congestion amplifies risk.
Before storms arrive, afternoon heat may stress outdoor workers as temperatures climb into the upper 80s to near 90 degrees by Tuesday, increasing fatigue risk during peak sun hours.
Drivers should slow down during rain and avoid water-covered roads, while residents should monitor midweek updates as storm chances increase.
The next impact window begins Wednesday between 3 p.m. and 8 p.m., when the first round of storms may disrupt travel across central Texas.
