A crisp stillness settles over San Antonio and the Hill Country this morning as temperatures dip near 30°F, triggering a Freeze Warning through 9 a.m. Tuesday. Cars glisten with frost, and thin layers of ice form on windshields and lawns — a rare winter wake-up call for early December in South Texas.
According to the National Weather Service in Austin/San Antonio, subfreezing temperatures were recorded in low-lying and rural areas overnight, while downtown and urban zones held in the mid- to upper 30s. The freeze has prompted officials to remind residents to protect pets, pipes, and plants, and to check on neighbors without reliable heat.
By late morning, clear skies and light winds will help temperatures rebound quickly, reaching the mid-60s by afternoon. The warm-up continues through midweek, with highs climbing near 76°F by Wednesday and remaining in the 70s through Friday — a 40-degree swing that perfectly captures Texas’s December weather whiplash.
The region will stay dry through the workweek, but early next week could bring light showers as Gulf moisture returns. For now, it’s all about the thaw. Expect sunny skies, calm winds, and a reminder that winter in Texas is anything but predictable.
