Texas – Warm, humid air is already settling over San Antonio this morning, and the heat will build quickly toward a summer-like afternoon. Temperatures climb near 89°F today, with a sticky breeze signaling bigger changes ahead.
According to the National Weather Service in Austin/San Antonio, southeast winds will gust up to 20 mph, pulling in moisture that fuels rising storm chances later this week. By Wednesday night, isolated storms begin developing, followed by a stronger 50% chance of thunderstorms on Thursday.
Across San Antonio, New Braunfels, and along the I-35 corridor, today remains mostly dry but increasingly humid. Drivers may notice gusty winds during the afternoon, especially on elevated roadways. By midweek, clouds increase and conditions turn more unsettled.
Thursday brings the most noticeable shift. Showers and thunderstorms could develop before the afternoon commute, producing brief heavy rain and lightning. Roads may become slick quickly after dry conditions, increasing the risk of sudden slowdowns.
Friday keeps skies mostly cloudy with lingering humidity, while only a slight chance of storms remains. By Saturday, rain chances increase again, with another round of showers and thunderstorms possible across South Central Texas.
Looking ahead, early April continues the warm trend, with above-normal temperatures holding steady even as periodic storms pass through the region.
