Texas – Crisp air bites early across south-central Texas as drivers step out to frosty windshields and cold pavement to start the MLK Day holiday. Temperatures hovered near freezing around San Antonio at sunrise, raising concerns for patchy frost and slick spots on bridges before the sun climbed higher.
According to the National Weather Service office in Austin–San Antonio, clear skies and calm winds allowed temperatures to dip near 32 degrees early today. Conditions improve quickly, with sunshine pushing highs into the upper 60s by afternoon, easing travel and outdoor plans across Bexar County.
The broader pattern favors a fast warm-up. Increasing clouds arrive late tonight, holding lows closer to the mid-40s. Tuesday stays gray but mild, topping out near 59 degrees. Moisture returns Tuesday night into Wednesday, when scattered showers could dampen roads, mainly during the morning commute. Rain amounts look light, but wet pavement combined with cooler mornings may still cause brief slick conditions.
By Wednesday afternoon, temperatures rebound into the mid-60s, followed by partly cloudy skies Wednesday night. Thursday brings the biggest shift. Sunshine dominates, highs climb into the low 70s, and the air feels more like early spring than winter across the metro.
Drivers should watch for early-day slick spots where frost melts, then refreezes in shaded areas. Plan extra time this morning, especially on elevated roadways like Loop 410 and U.S. 281. Keep layers handy, to be fair, temperatures swing fast this week.
Looking ahead, longer-range outlooks hint at rising rain chances across parts of the central U.S. later next week, while warmer air builds in the Southwest. For now, San Antonio settles into a quieter, warmer stretch after today’s freeze.
