Texas – A cool dawn settles across South-Central Texas as thin fog clings to low fields and streetlights glow through the damp air. The warm-to-cool contrast tells the story of the days ahead: rising humidity, building clouds, and increasing rain chances that may affect Friday travel across San Antonio. Slick pavement could form quickly after showers, especially during the morning and evening rush windows.
According to the National Weather Service, scattered showers begin to develop late tonight and expand into Thursday. Light rainfall persists through Friday as a steady south wind feeds moisture into the region. Winds may gust toward 20 mph, a setup that often produces quick shifts in drizzle intensity and reduced visibility on I-10, I-35, and Loop 410. Drivers should allow extra travel time, especially if rain bands thicken by midday Friday.
Temperatures climb into the mid-60s today before dipping into the lower 50s tonight. By Thursday, another surge of moisture fuels a 50 percent chance of showers, with temperatures falling to the upper 40s by evening. A 30 percent rain window remains Friday as cooler, drier north winds begin to filter in. Pavement may stay damp for hours, creating the familiar early-December “slick glaze” that increases the risk of low-speed collisions.
Meteorologists now track a wider pattern change taking shape across the country. An Arctic blast grips the northern states, and while that deep freeze stays far north of Texas, the sharper temperature gradient may help increase small pockets of heavier rainfall through early next week.
Five-Day Outlook:
• Friday: 54° with 30% showers, becoming cloudy late.
• Saturday: Mostly sunny, high 70°.
• Sunday: Sunny, high 72°.
• Monday: High 68°, mostly clear.
• Tuesday: Partly cloudy, high near 67°.
