SAN ANTONIO, Texas – Fall warmth is hanging on across South Texas this morning, but change is already on the horizon. Skies stay clear and breezy heading into the weekend, yet a sharp north wind by late Saturday will deliver a reminder that November can turn quickly. Residents planning outdoor Veterans Day events or early holiday travel should prepare for cooler, gustier air and falling temperatures by Sunday.
According to the National Weather Service in Austin–San Antonio, highs near 89°F on Saturday will tumble by nearly 20 degrees by Sunday afternoon as a dry cold front sweeps south through the Hill Country and along I-35. Winds may gust up to 35 mph, especially north of Loop 1604 and along open stretches toward New Braunfels and Seguin. The front won’t bring rain, but it will push overnight lows into the low 40s by early Monday.
The combination of crisp air and low humidity will make for ideal conditions for outdoor cleanup or early Christmas decorating, though gusty winds could briefly complicate travel for high-profile vehicles on elevated highways. For now, no frost or freeze is expected this far south, but forecasters hint at a stronger cold snap developing across the central U.S. next week — a possible early taste of winter air sliding toward Texas near midmonth.
With much of the country cooling rapidly — and some northern states already seeing their first measurable snow — San Antonio remains one of the last warm holdouts before the season fully shifts. Residents should secure loose decorations, hydrate during outdoor activities, and stay weather-aware for Sunday’s brisk change.
