Texas starts the morning wrapped in low clouds and damp air, with puddles shining under streetlights across South Texas. It feels mild now, but a sharper edge is already approaching as weather conditions change quickly heading toward the weekend.
According to the National Weather Service in San Antonio, today stays mostly cloudy with a slight chance of showers and patchy fog early. Highs climb into the upper 60s, and roads may remain damp through the morning. Visibility could briefly dip in low-lying areas.
Tonight stays mild, with temperatures holding in the low 50s. Thursday brings a brighter break. Skies turn partly sunny, and highs rise into the low 70s, offering one last warm day before colder air arrives.
Changes accelerate Friday. Showers become more likely by afternoon, with rain chances increasing into Friday night. Temperatures peak near 70 early, then fall steadily as winds turn north. Roads may become slick during periods of heavier rain.
By Saturday, winter impacts grow more noticeable. Highs struggle to reach the upper 30s, and rain continues at times. Cold air deepens through the day, setting the stage for freezing concerns after sunset. Bridges and elevated roadways cool faster than surface streets.
Saturday night brings the highest risk window. Temperatures drop into the low 20s. Rain may mix with or change to freezing rain, especially across northern parts of the metro. Even light icing could cause travel problems and isolated power concerns.
Sunday remains cold. A slight chance of freezing rain lingers early before clouds thin. Highs reach the mid-30s, but any melted moisture could refreeze quickly after dark.
Looking ahead, the 6–10 day outlook keeps Texas split, with colder-than-normal air lingering east while much warmer conditions build across the Southwest.
