Texas — Headlights glow softly through thick gray air as fog hugs freeways and neighborhoods before sunrise.
Early this morning, Houston sits near 68 degrees, but visibility drops quickly in spots. A Dense Fog Advisory remains in effect until 10 a.m., creating hazardous travel for early Christmas drivers. Moist air and calm winds allow fog to thicken, especially near bayous and low-lying roads.
Expect slow travel during the morning hours. Visibility may dip below a quarter mile at times. Drivers should reduce speed, use low-beam headlights, and allow extra stopping distance. Conditions gradually improve late morning as clouds lift.
Once fog clears, the day turns quiet. Afternoon temperatures climb toward 79 degrees, with filtered sunshine and light south winds. Roads dry out, and travel conditions improve significantly by midday.
Tonight, fog threatens again. Patchy dense fog redevelops after dark, especially south and east of downtown. Late-night drivers should stay alert for sudden visibility drops.
Friday and Saturday keep the warm pattern locked in. Highs reach 80 to 81 degrees, feeling more like early fall than late December. Morning fog remains possible both days, then skies turn partly sunny. Winds stay light, limiting any weather disruptions for weekend plans.
By Sunday, clouds increase as the pattern begins to change. Highs still approach 80 degrees, but the air feels heavier. Fog may form early, then lift by late morning. A 40 percent chance of showers arrives Sunday night, signaling an approaching cold front.
Conditions shift quickly after sunset Sunday. Winds turn breezy, and temperatures fall sharply. Wet roads may greet late travelers, especially during evening returns.
Monday brings a very different feel. Highs struggle near 55 degrees, with brisk winds adding a winter bite. Monday night drops into the upper 30s, the coldest air Houston has felt in days.
For now, navigate fog carefully this morning. Enjoy the warmth while it lasts, and plan ahead for changing conditions during post-Christmas travel into early next week.
