How This Weather Will Impact San Antonio
Massive Temperature Swings: The biggest shock will come on Saturday night, when a warm, sunny afternoon turns into a freezing night. If you’re heading out during the day, bring a jacket—because by evening, you’ll need it.

Check Heating Systems: If you haven’t turned on the heater in a while, test it now before the cold front arrives. Make sure it’s working before you actually need it.
Protect Pets and Plants: Bring pets indoors before temperatures drop on Saturday night. If you have sensitive plants, cover them up or bring them inside.
Be Ready for Stronger Winds: Secure patio furniture, outdoor decorations, and trash cans before Saturday night’s gusty winds move in.
Monitor Local Weather Alerts: Stay updated on weather conditions in case temperatures drop even lower than forecasted.
