Texas – A warm breeze and thick humidity are setting the stage across San Antonio, where clouds are building and storms are beginning to organize heading into the afternoon.
According to the National Weather Service, scattered showers and thunderstorms develop early, with about a 40% chance of rain before midday. Temperatures climb toward 86°F, and gusty southeast winds up to 20 mph will help fuel additional storm development.
Across San Antonio, including I-35, Loop 410, and US-281, drivers could encounter quick bursts of rain that turn roads slick within minutes. Visibility may drop during heavier downpours. Plan extra travel time and keep headlights on.
Storm chances ease slightly later today, but the atmosphere stays primed. By Friday, warmer air pushes highs near 89°F, with only isolated storm chances during the day. Conditions remain humid and unstable.
The pattern shifts sharply into the weekend. By Saturday afternoon, rain chances surge to 90%, with showers becoming widespread and thunderstorms likely. Periods of heavier rain could lead to localized street flooding, especially in low-lying areas and along creeks.
Saturday night keeps storms active, with continued rain and gusty winds. Travel conditions may remain difficult into early Sunday before rain begins to taper. Sunday still carries a 40% chance of lingering showers, with cooler highs near the upper 60s.
Looking ahead, early next week trends quieter, though a few showers may linger before gradual clearing and warmer temperatures return.
This active spring setup is part of a broader system impacting much of the central and southern U.S., bringing waves of storms and shifting temperatures.
