Texas — A thick, soupy haze clings to the early sky this Saturday as warm Gulf air presses into San Antonio. Streetlights glow through the mist, and the pavement carries a dull sheen — a quiet preview of the much heavier rain lining up for South-Central Texas just as Thanksgiving travel accelerates.

A Flood Watch remains in effect as deep moisture surges north, feeding a storm system expected to unload 1–3 inches of rain, with isolated 6-inch pockets possible. Residents traveling along I-35, I-10, or Loop 1604 should watch for fast-changing conditions. Low-water crossings may flood quickly, and the Hill Country tends to respond faster than drivers expect. Early travelers heading out for holiday plans should pack extra time and keep alternate routes in mind.

Forecasters say showers and thunderstorms grow more widespread Wednesday night and continue through Thursday. An upper low drags a Pacific cold front across the region, triggering repeated rounds of rain from the Edwards Plateau into the metro. Some storms may produce locally heavy rainfall strong enough to push creeks and streams out of their banks. To be fair, severe thunderstorms look unlikely, but runoff alone could pose significant travel hazards.

By Friday, the system finally edges east, though lingering showers may still slow airport traffic and regional travel corridors. Roads may remain slick, and any saturated areas could struggle to drain. However, models hint at a welcomed shift for Thanksgiving week: drier air, lighter winds, and seasonable warmth returning by Saturday.

For now, San Antonio sits at the front edge of a wet November pattern. Drivers should monitor alerts, check low-water crossing reports, and stay ready for rapid changes — especially with the Thanksgiving rush beginning in earnest.
