San Antonio, Texas – Afternoon thunderstorms and rising temperatures will dominate South-Central Texas this week, with San Antonio and surrounding areas likely to see isolated storms and highs near 100°F through Thursday.
According to the National Weather Service in Austin/San Antonio, a weak upper-level disturbance could trigger scattered afternoon and evening showers, especially across the Edwards Plateau and northeast counties starting Sunday. The storms are expected to be brief and isolated, bringing minimal impact but possible lightning and gusty winds.
Cities including Austin, Kerrville, and Del Rio will feel the heat rise steadily, with highs peaking at 100°F by midweek in places like Eagle Pass and San Antonio. Lows will stay warm overnight, ranging from the upper 60s to upper 70s. Drivers and outdoor workers should take heat precautions during peak afternoon hours. Stay hydrated, limit outdoor activity, and never leave pets or people in parked vehicles.
This week’s weather mirrors a typical early June pattern across Central Texas: scattered convection and surging heat. While severe weather is not expected, brief downpours or lightning could affect isolated areas.
Daily chances for storms continue through Thursday, with another update expected midweek if conditions change.
