Some short-range forecast guidance indicates a growing risk for locally heavy rain across parts of South-Central Texas overnight into Saturday morning. Rainfall amounts of 3 to 5 inches will be possible in localized areas, which may result in isolated flooding concerns — especially in low-lying or poor-drainage locations.

The highest potential for heavier rain appears to be in areas near and west of San Antonio, including portions of Uvalde, Medina, Frio, and surrounding counties. Stay weather-aware and monitor official updates if you are in the affected region.
