San Antonio, TX – South Texas residents are enjoying one last stretch of late-fall warmth before a strong cold front sweeps through the region this weekend, bringing cooler, gustier air and a sharp drop in temperatures by Sunday. The National Weather Service (NWS) in Austin–San Antonio says the change will be noticeable, with temperatures tumbling nearly 20 degrees within 24 hours.
The Current Conditions: Warm and Breezy Ahead of the Front
Skies remain clear and sunny across San Antonio and the Hill Country, allowing warm afternoon highs to climb into the upper 80s through Saturday. Light south and southwest winds will keep humidity low, making for pleasant outdoor weather heading into the weekend.
However, forecasters caution that this warm pattern will break abruptly as a cold front pushes south through the I-35 corridor late Saturday night.
According to NWS forecasters, highs near 89°F on Saturday will give way to temperatures in the 60s and low 70s by Sunday afternoon.
“A sharp north wind will arrive late Saturday, bringing a noticeable drop in temperatures and much drier air by Sunday,” the NWS said in its latest forecast discussion.
The Cold Front: Gusty Winds and Cooler Air Incoming
The cold front is expected to reach San Antonio late Saturday night, ushering in strong north to northwest winds that could gust up to 35 mph in exposed areas. Breezy conditions will extend into Sunday morning, especially north of Loop 1604 and toward New Braunfels and Seguin.
Despite its strength, the front will remain dry, with no rain expected. The main impact will be a 20-degree temperature drop and brisk winds that could affect Veterans Day events or early holiday travel plans.
Meteorologists say overnight lows could dip into the low 40s by early Monday, creating a crisp, cool start to the new week.
Outdoor Impact: Great for Cleanup, But Watch the Wind
The incoming cooler air will bring comfortable humidity levels, making it an excellent window for yard cleanup, outdoor projects, or early Christmas decorating. However, the gusty winds may briefly complicate travel for high-profile vehicles on bridges and elevated highways Saturday night into Sunday.
Forecasters recommend securing outdoor decorations and inflatables ahead of the front and staying hydrated during outdoor activities, as dry air can cause mild dehydration even in cooler conditions.
“The combination of clear skies and lower humidity will make Sunday feel like a true fall day,” forecasters noted, “but winds may stay strong into the afternoon before calming by evening.”
Broader Weather Context: Early Signs of Winter Across the U.S.
While San Antonio remains one of the warmest major cities in the nation this week, much of the country is already transitioning into winter conditions. Northern states, including parts of the Midwest and Great Lakes, have recorded their first measurable snowfall of the season.
Meteorologists say a stronger cold snap could develop next week across the central U.S., with colder air possibly reaching Texas by midmonth, hinting at the state’s first real taste of winter.
