Texas wakes up wrapped in gray, with headlights glowing through thick mist.
Visibility drops suddenly, turning familiar roads into slow-moving corridors. This Weather matters now because Christmas Eve travel is already underway.
A Dense Fog Advisory remains in effect until 10 a.m. CST for much of the Houston metro area. The National Weather Service reports visibility reduced to one-quarter mile or less in dense fog. Affected areas include Harris, Montgomery, Fort Bend, Brazoria, Jackson, Wharton, and Inland Chambers counties.
Early travel remains hazardous. Fog pools along highways, frontage roads, and residential streets. Drivers encounter rapidly changing visibility, especially near waterways and low-lying areas. Slow down, use low-beam headlights, and leave extra following distance.
Conditions improve gradually late this morning as fog lifts and clouds thin. Temperatures climb into the upper 70s, delivering a mild Christmas Eve afternoon. Roads dry out, easing daytime travel across the region.
Christmas Day stays warm and mostly sunny, with highs near 78 degrees. Patchy fog may redevelop early but clears faster than today. No winter precipitation is expected, keeping Christmas travel mostly smooth.
Fog returns as a recurring issue later this week. Thursday night into Friday morning, widespread fog is likely again, especially before sunrise. Friday afternoon turns warmer, with highs near 80 degrees once fog clears.
Saturday, December 27, looks favorable for post-Christmas travel. Morning patchy fog fades, followed by partly sunny skies and highs near 79 degrees. Drivers heading out early should still watch for brief visibility drops.
Looking ahead, a cooler pattern develops late in the weekend. Sunday night brings a chance of rain, followed by cooler air early next week. Temperatures drop into the 40s, hinting at the first real winter feel.
