Houston, TX – Drivers across the Houston metro could face dangerous visibility conditions overnight and into the Thursday morning commute as dense fog settles in across southeast Texas.
According to the National Weather Service in Houston/Galveston, a Dense Fog Advisory remains in effect until 9 a.m. Thursday for much of south central and southeast Texas, including Harris, Fort Bend, Brazoria, Montgomery, Galveston, and Liberty counties. Visibility may drop to a quarter mile or less in the thickest fog, especially on highways, bridges, and near coastal and low-lying areas.
The fog developed Wednesday evening and is expected to become more widespread through the night before slowly lifting mid to late Thursday morning. Travel could be hazardous on major routes including I-10, I-45, U.S. 59, the Grand Parkway, and area causeways. Drivers are urged to slow down, use low-beam headlights, and leave extra distance between vehicles.
Once the fog clears, conditions improve quickly. Thursday turns warm and mostly sunny, with highs climbing into the mid to upper 70s. Dry and pleasant weather continues Friday and through the weekend, offering ideal conditions for outdoor plans.
Looking ahead, the calm pattern holds into next week. Christmas Eve on Wednesday is currently shaping up warm and dry across the Houston area, with highs in the mid to upper 70s, favorable for holiday travel and last-minute preparations. The Dense Fog Advisory remains in effect through Thursday morning, and additional updates may be issued if visibility worsens overnight.
