Temperatures will drop below freezing before sunrise Sunday morning, so that’s when icing is likely to begin around Bexar County and San Antonio. It’s best to avoid travel Saturday night and especially Sunday morning.
SUNDAY
Icing likely in the morning, which is when it should be the most hazardous to travel around the Alamo City.
By early afternoon, all precipitation will end, and we may even briefly rise above freezing. However, temperatures will plummet Sunday night with readings in the lower 20s Monday morning.
IMPACTS FROM ICE
Potential Ice impacts (Copyright 2026 by KSAT – All rights reserved.)
Because more ice accumulation is expected in the Hill Country, this is where impacts will be greatest. Accumulations of up to 0.25″ to 0.50″ are possible north of San Antonio. This kind of ice can cause tree limbs to break and power lines to sag, leading to the risk of power outages.
Generally less accumulation is expected in San Antonio — a glazing to 0.10″. This can still be dangerous, though, and cause slick spots on bridges and overpasses. But concern for widespread power outages around the Alamo City is much lower than the Hill Country.
IMPACTS FROM COLD
Expect to be below freezing for at least 24 hours and perhaps even longer, depending on temperatures Sunday afternoon. Sunday, Monday, and Tuesday mornings will be well below freezing.
Now is the time to prepare your home for extended cold: insulate exposed pipes, cover outdoor faucets, make sure your pets will be inside with you this weekend and early next week.
