Texas drivers ease into the morning under a blanket of gray. Headlights glow through mist as dense fog settles across San Antonio and the Hill Country.
A Dense Fog Advisory remains in effect through the morning hours. Visibility drops to one-quarter mile or less in pockets, especially along the Escarpment and into surrounding Hill Country communities. Travel conditions can change block by block.
Morning commuters face the greatest risk. Fog thickens along I-10, I-35, Loop 410, and Highway 281, where sudden visibility loss may catch drivers off guard. Slow down, increase following distance, and use low-beam headlights.
Temperatures hold near 59 degrees, with saturated air keeping fog slow to lift. Patchy mist and drizzle may linger even after visibility improves. Roads stay damp, though icing is not a concern locally.
By late morning, conditions gradually improve. Clouds thin, and warmer air takes over. Afternoon highs climb near 69 degrees, creating a springlike December feel. Winds stay light, helping skies partially clear tonight.
Thursday brings another round of patchy morning fog before sunshine dominates. Highs reach the upper 70s, well above seasonal norms. Friday stays bright and warm, with highs near 69 degrees and dry travel conditions.
Looking ahead to the Christmas Travel window, South Texas avoids winter hazards for now. While colder air and snow target the Midwest and Plains, local models show continued mild weather. Still, fog remains a recurring early-morning risk this time of year.
What You Should Do:
Allow extra travel time this morning. Avoid sudden stops. Watch for stalled vehicles in low-visibility zones.
