Texas — Headlights glow through pockets of fog across San Antonio early this morning, briefly blurring exits and neighborhood streets. Damp air settles low near road level, especially along I-10, I-35, and Loop 410. Visibility improves quickly once the sun gains strength.
According to the National Weather Service, patchy fog develops during the early morning window before clearing by midmorning. Winds stay light, allowing moisture to linger near the ground. Drivers should slow down and allow extra space, particularly on bridges and shaded stretches.
Skies brighten late in the morning, and temperatures climb fast. Afternoon highs reach the mid-70s, delivering a springlike December feel. To be fair, this warmth feels welcome, but fog remains the main concern during early travel hours.
Sunday follows a similar pattern. Fog forms again before sunrise, then sunshine takes over. Highs rise into the mid-70s, keeping outdoor plans comfortable. For now, winter stays quiet across South Texas, with no freeze threats on the horizon.
By Monday, clouds increase slightly, though rain stays out of the picture. Highs reach the upper 70s, reinforcing the warm trend. This stable setup benefits holiday travel, though fog could still surprise early commuters.
Looking ahead toward Christmas week, temperatures continue climbing. Afternoon highs push near 80 degrees by Tuesday and Wednesday. Nights remain mild, limiting cold-weather concerns but increasing fog potential during calm mornings.
Travelers heading out for Christmas should plan around reduced visibility during early departures. Keep low beams on in fog, avoid sudden stops, and allow extra drive time. Conditions improve rapidly after sunrise each day.
