Houston, TX – The glow of streetlights cuts through thick, low fog across the Houston metro early this morning, as drivers navigate near-zero visibility in spots from Conroe to Galveston. The National Weather Service in Houston/Galveston has issued a Dense Fog Advisory in effect until 7 a.m. CST Sunday, with visibility dipping below a quarter mile along and east of Interstate 45.
Commuters should prepare for slower travel through sunrise, particularly along Highways 59, 290, and coastal routes near League City and Galveston Island. Forecasters warn that fog will gradually lift midmorning, revealing mostly sunny skies and highs climbing to the low 70s — a reminder that December in Texas can still feel more like late fall than winter.
Experts urge drivers to use low-beam headlights, avoid high beams, and allow extra distance between vehicles. Even familiar roads may feel unfamiliar under heavy fog, especially near the coast and rural areas where humidity stays high.
By Monday and Tuesday, dry air and clear skies return, with highs around 60–63°F. The week ahead looks calm and mild — perfect for early holiday errands or outdoor decorating — though models hint at cooler air late next weekend as the next front dips south.
