by San Antonio, Texas — Headlights cut through pockets of dense fog early this morning as drivers eased onto local roadways before sunrise. Visibility dropped in low-lying areas across the city, creating a slower-than-usual start to the day for commuters traveling along major corridors like I-10, I-35, and Loop 410.
Early temperatures hovered near 68 degrees, and with light winds, fog was able to linger longer than usual. Drivers heading out before mid-morning were advised to allow extra travel time and use caution, especially near overpasses and shaded stretches of road. As the morning progresses, visibility steadily improves as clouds thin and air movement increases slightly.
By late morning, conditions turn noticeably more comfortable. Once fog clears, sunshine filters through lingering clouds, allowing temperatures to climb to around 79 degrees. Road conditions improve significantly, making late-morning and afternoon travel smooth across the city. For Christmas Day travelers, the weather cooperates with dry pavement, mild temperatures, and manageable winds.
Calm and Mild Conditions Tonight
Tonight remains quiet across the region. Cloud cover holds overnight, helping temperatures stay relatively warm for late December. Lows dip only to around 66 degrees, keeping overnight travel dry and uneventful. No precipitation or hazardous weather is expected, and visibility issues do not redevelop.
Friday continues the warming trend. Gradual clearing allows sunshine to dominate through the afternoon, pushing highs to near 81 degrees. Winds stay light, and humidity remains low, creating one of the most travel-friendly days of the holiday stretch. Drivers heading out of town or returning home should encounter excellent road conditions across South Texas.
Saturday Brings Above-Average Warmth
Saturday holds onto the unseasonably warm pattern. Partly sunny skies help temperatures rise close to 80 degrees, well above December averages for the region. Outdoor activities remain safe, and there are no weather-related disruptions expected for travel or events.

With dry air in place and no storm systems nearby, Saturday offers another calm day for residents and visitors alike. Roads remain clear, and visibility stays high throughout the day and evening hours.
Pattern Shifts on Sunday
Weather conditions begin to change Sunday afternoon. Clouds increase steadily, and winds start to pick up as a weak front approaches from the north. Despite the change, daytime highs still reach around 79 degrees, maintaining the warm feel through much of the day.
By Sunday night, a 20 percent chance of showers develops as the front moves through. While rainfall amounts look light, gusty north winds follow closely behind. These stronger winds may create choppy driving conditions, particularly on elevated roadways and open stretches of highway. Residents are encouraged to secure loose outdoor items ahead of the wind shift.
Cooler Air Settles In Monday
Monday marks a noticeable cooldown. High temperatures drop to near 52 degrees, nearly 30 degrees cooler than the weekend highs. Clouds linger through much of the day, and a slight chance of early showers remains before conditions gradually dry out.
Winds ease later Monday, but the cooler air lingers, making it feel distinctly more like winter for post-holiday travel. While no major weather hazards are expected, the temperature change may catch some residents off guard after several warm days.
Gradual Improvement Midweek
Looking ahead, Tuesday brings calmer conditions with increasing sunshine. Highs rebound slightly to around 55 degrees, with gradual warming expected as the week progresses. The overall pattern remains dry and stable heading toward the end of December.
For now, motorists should navigate cautiously through early-morning fog today, take advantage of the warm and travel-friendly weekend, and prepare for a breezy, cooler shift as Sunday night approaches.
