Texas – Headlights glow through low clouds this morning as fog clings to neighborhoods and feeder roads. The air feels humid and springlike, but changes line up quickly as weekend travel builds and winter edges closer.

Early today, patchy fog reduces visibility across parts of the Houston metro. Drivers along I-10, I-45, and Highway 59 should slow down through the morning hours. Conditions improve by mid-morning as clouds thin. Afternoon highs climb near 80 degrees, keeping travel smooth once fog lifts.

Tonight stays warm and damp, with lows near the upper 60s. Fog redevelops late, especially near bays, bayous, and low-lying roads. Saturday follows a similar pattern. Morning fog fades, then sunshine breaks through. Highs again reach around 80 degrees, ideal for errands and holiday gatherings.

Sunday remains warm, with highs near 81 degrees. Clouds increase through the day, and winds slowly shift. By Sunday night, a weather system approaches from the west. Showers become more likely after midnight, and a few thunderstorms could develop. Wet pavement may affect late-night drivers and early Monday commuters.

Monday brings a noticeable change. Temperatures fall sharply behind the system, with highs only in the mid-50s. Breezy conditions add a chill, especially during the morning. Any lingering showers taper off early, but the cooler air settles in for good.

Monday night turns crisp, with lows dropping into the mid-30s across parts of Southeast Texas. While a freeze is unlikely inside the city, jackets will be needed for early travel. Tuesday stays cool and dry, with highs near 51 degrees.

Looking ahead to New Year’s Eve on Wednesday, temperatures rebound into the upper 60s with calmer conditions expected for evening plans. Until then, plan for fog delays early, rain late Sunday, and a sharp cooldown to start the final week of December.
