Texas – Low clouds hang over San Antonio this morning, but breaks in the sky are already allowing heat to build fast across the region. Roads remain dry for now, yet increasing humidity and gusty winds signal a shift toward stormier conditions later this week.
According to the National Weather Service, San Antonio will climb to near 89°F today after gradual clearing, with southeast winds between 10 and 15 mph and gusts up to 25 mph. That steady Gulf flow continues into Tuesday, pushing temperatures near 90°F and setting up a warmer, more unstable pattern.
By midweek, the atmosphere becomes more active. Wednesday brings highs near 92°F with partly sunny skies, but changes arrive quickly after sunset. A 20% chance of showers and thunderstorms develops late, especially across Bexar County and surrounding areas.
Storm coverage increases by Thursday, with a 40% chance of thunderstorms. Brief downpours and lightning could impact travel along I-35, Loop 410, and Highway 281. Expect slick roads during heavier showers and allow extra time for the commute.
Humidity stays elevated into late week, keeping conditions muggy even as temperatures ease slightly into the upper 80s. Additional storm chances linger into Friday and the start of the weekend.
Looking ahead, early April trends warmer than normal, reinforcing a spring pattern of heat followed by periodic storms. More advisories may be issued as storm chances increase.
