SAN ANTONIO, Texas – Warm air clings to the early morning hours across the Alamo City, the kind that feels more like late summer than mid-fall. Streetlights shimmer through thin patches of mist near the River Walk, while a soft breeze rolls off the Hill Country. South-central Texas will see yet another unseasonably warm start to the week before a slight dip in temperatures arrives midweek.
According to the National Weather Service in Austin/San Antonio, Monday’s highs will surge into the mid-90s, challenging daily records across Bexar, Comal, and Guadalupe counties. Skies remain mostly sunny with light south winds, and drivers should brace for bright glare and hot pavement through the afternoon. Heat-sensitive individuals should stay hydrated and limit strenuous activity during peak hours.
By Tuesday, patchy morning fog could slow commuters along I-10 and Loop 410, especially in low-lying areas south of the city. Sunshine quickly returns, though highs remain near 91°F before a weak front nudges in from the north Tuesday night. That front won’t bring rain, but it will deliver slightly cooler and drier air for Wednesday, with highs settling near 88°F.
Looking toward the weekend, long-range models suggest a pattern shift by late Friday or Saturday, possibly opening the door to isolated showers and a modest cooldown. While no major cold front appears imminent yet, forecasters say this could mark the beginning of Texas’ transition away from extended heat — the first hint that true fall weather may finally be on the way.
