Cloudy Skies and Balmy Breezes: San Antonio Braces for a Warm Thursday
A Warm and Gray Thursday Across the Alamo City
As San Antonio wakes up this Thursday, February 12, 2026, residents can expect a day defined by heavy cloud cover and unseasonably warm temperatures. While the winter calendar might suggest a chill, the atmosphere is telling a different story, with moisture-rich air flowing in from the Gulf Coast to keep the city feeling more like early spring than mid-February.
Morning: A Soft, Humid Start
The early morning hours began with temperatures hovering around a comfortable 56°F. Commuters likely noticed a mix of high and low clouds stretching across the South-Central Texas horizon. According to the latest observations from the San Antonio International Airport, humidity levels are sitting near 72% this morning, creating a slightly damp feel to the air despite the lack of active rainfall. While the Rio Grande valley is seeing thicker low-level clouds, San Antonio is currently experiencing a wispy cloud layer that will thicken as the morning progresses.
Afternoon: Peaking in the High 70s
By midday, the cloud deck will shift from partly cloudy to mostly cloudy, dominating the sky. Despite the lack of direct sunshine, the mercury is set to rise significantly. We are looking at an afternoon high of 79°F, which is nearly 13 degrees above the historical normal for this date. These warm conditions are being driven by consistent southerly winds bringing in balmy air. For those planning outdoor lunch breaks or errands, the 25% chance of light rain should not be a dealbreaker, but a light jacket or umbrella might be worth keeping in the car just in case a stray shower develops.
Evening and Overnight Outlook
As the sun sets, the blanket effect of the overcast skies will prevent temperatures from dropping too sharply. The evening prediction holds steady with cloudy conditions and a low of 55°F. The chance of precipitation remains low at 20% overnight. Humidity will remain a factor, staying around 56% throughout the later hours, ensuring that the air remains mild through Friday morning.
Safety and Alerts
There are currently no active wind or rain warnings for the San Antonio area. However, drivers are encouraged to remain vigilant for patches of morning mist or low visibility in lower-lying areas. While no severe weather is expected today, the National Weather Service indicates that this warm, cloudy pattern is a precursor to higher rain chances expected later in the week.
