San Antonio, Texas – Another surge of cold air is moving into Central and South-Central Texas this weekend, bringing dangerously cold wind chills and temperatures well below normal before milder conditions return early next week.
According to the National Weather Service Austin–San Antonio, a reinforcing cold front will arrive early Saturday, ushering in colder and breezier conditions across the region. While Friday remains mostly cloudy and cooler, Saturday and Sunday mornings will be the coldest, with temperatures dropping into the teens and 20s across much of the area.
North winds of 10 to 20 mph, with occasional gusts near 25 mph, will combine with the cold air to produce wind chill values in the upper teens to lower 20s, particularly along and east of the Interstate 35 corridor, including Austin, San Marcos, New Braunfels, and San Antonio. These conditions may prompt Cold Weather Advisories, especially during the overnight and early morning hours.
High temperatures on Saturday are expected to remain below normal, generally reaching the 40s to low 50s, before slowly moderating Sunday afternoon. Overnight lows Saturday night into Sunday morning will again fall into the 20s and lower 30s, keeping cold exposure risks elevated for those spending extended time outdoors.
Motorists traveling along I-35, I-10, U.S. Highway 290, and State Highway 71 should be prepared for brisk crosswinds, especially during the morning hours. While no wintry precipitation is expected, the cold and wind may impact outdoor activities, early commutes, and vulnerable populations.
Looking ahead, temperatures will trend milder by Monday, with highs returning closer to seasonal averages. Forecast models also indicate a slight chance of rain by Tuesday and Wednesday, though rainfall amounts are expected to be light at this time.
Residents are urged to dress in layers, protect pets and plants, and check on neighbors who may be sensitive to cold conditions. Continue monitoring official updates from the National Weather Service for any advisory changes.
