AT A GLANCE
- What’s happening: San Antonio is facing a likely 48-hour freeze from early Saturday through Monday.
- Prolonged subfreezing temps raise the risk of icy roads, pipe damage, and cold-related health risks.
- What to do before weekend freeze: Insulate pipes, protect pets and plants, limit travel, and monitor local forecasts.
Weekend Arctic Blast Could Bring 48 Hours Below Freezing
San Antonio is bracing for an unusually long stretch of freezing temperatures this weekend, with forecasters predicting a likely 48-hour period at or below freezing beginning early Saturday morning and lasting through Monday.
A strong arctic cold front is expected to move into South Texas late Friday, bringing sharply colder air and increasing the potential for a wintry mix of freezing rain, sleet, or light snow across parts of the region. While snowfall in San Antonio is not guaranteed, the interaction between cold air and moisture could create icy conditions, especially overnight.
Details of the Freeze Forecast
Temperatures are expected to remain at or below 32 degrees for much of Saturday and Sunday, with the coldest conditions occurring during overnight and early morning hours. Forecast models suggest freezing conditions could persist for nearly two full days, an extended duration that is uncommon for the region.
Areas north and west of San Antonio, including the Hill Country, may face a higher risk of icy roads and hazardous travel conditions. Even light ice accumulation could significantly impact bridges, overpasses, and untreated roadways.
Pets, Plants and Pipes and People
Extended freezing periods are rare in San Antonio and can place added strain on infrastructure not designed for prolonged cold. Exposed pipes, irrigation systems, and outdoor plumbing are especially vulnerable, and residents are encouraged to insulate pipes, drip faucets, and take precautions to prevent damage.
Cold temperatures can also pose risks to pets, plants, and those without adequate heating. Residents are urged to check on elderly neighbors and ensure outdoor animals have warm shelter.
Preparing for the Cold Snap
While this weather event is not expected to match the severity of past historic winter storms, officials stress that prolonged freezing temperatures alone can create serious challenges if households are unprepared. Residents are encouraged to stock essential supplies, limit travel during icy conditions, and monitor local forecasts as conditions evolve.
Temperatures are expected to gradually rebound early next week as the arctic air mass moves out of the region.
