Austin, Texas – Low clouds and areas of fog across Central Texas may affect visibility during the morning hours on Christmas Eve and Christmas Day before giving way to sunshine and near-record warmth.
According to the U.S. National Weather Service office in Austin–San Antonio, dense fog is possible this morning, particularly across the Coastal Plains and along the Interstate 35 corridor. Visibility could drop to one-quarter mile or less in some locations, prompting caution for early holiday travel.
The National Weather Service reports that fog and low clouds should gradually clear by late morning or early afternoon, allowing for sunshine and well-above-normal temperatures. Highs on Christmas Eve are forecast to reach the upper 70s to lower 80s across much of Central Texas, including Austin, San Antonio, San Marcos, and surrounding communities.
Similar conditions are expected on Christmas Day, with fog again possible during the morning hours followed by sunny skies and very warm afternoon temperatures. Forecast graphics shared by the agency show highs continuing well above seasonal averages, with some locations approaching daily record levels.
Near-record warmth is expected for late December, though the National Weather Service did not specify exact probabilities for record-breaking temperatures in this update. Overnight lows are also forecast to remain mild, generally in the upper 50s to lower 60s.
The combination of dense morning fog and increased holiday travel could create brief but notable impacts, especially during early commutes and Christmas morning travel. Officials advise drivers to slow down, use low-beam headlights, and allow extra following distance when encountering fog.
By the afternoon hours, conditions are expected to be favorable for outdoor holiday activities across much of the region.
Residents are encouraged to monitor updated forecasts and local visibility conditions, particularly if traveling during the early morning hours.
