Houston woke up Sunday morning to thick fog and mist, with visibility down to about a quarter mile in some areas and temperatures around 52°F. The fog slowed early morning traffic, especially in low-lying and coastal areas where moisture built up overnight. Drivers should expect delays and allow extra time for travel between 6 and 9 a.m, according to the National Weather Service.
What To Expect This Morning
The National Weather Service has a Dense Fog Advisory in place through 9 a.m. CST, warning that visibility could fall to one-quarter mile or less and that "low visibility could make driving conditions hazardous." In plain terms, if you are heading out, take it easy and give yourself space. The fog is expected to thin by mid-to-late morning, with skies trending mostly sunny and a high near 76°F, along with south winds around 5 to 10 mph. For official timing, map details, and county-by-county coverage, check National Weather Service Houston/Galveston.
Afternoons Should Clear Up
Most neighborhoods should watch the fog burn off by mid-morning and then enjoy a warm, mostly sunny afternoon, a fast turnaround from the gray start. The broader warm-and-foggy setup has already been in play this weekend, and we broke it down yesterday, including where fog is most likely to linger south of I-10 and near Galveston Bay: Sunny Weekend, Patchy Fog, Tuesday Storms.
Looking Ahead
Patchy to areas of fog are likely to return overnight through midweek as southeasterly flow keeps lows in the upper 50s to low 60s. A weak disturbance arriving Tuesday brings about a 30 percent chance of showers and scattered thunderstorms in the afternoon and evening. Most spots should stay dry, but isolated stronger cells are on the table, according to NWS Houston/Galveston. High temperatures should hold in the mid-to-upper 70s through Thursday before any late-week pattern shift.
Practical Tips For Drivers And Boaters
If you have to drive this morning, slow down, use low-beam headlights, and leave extra stopping distance. When visibility drops below a quarter-mile, it is worth thinking about delaying any nonessential trips. Boaters should plan for sea fog near the coast tonight, lean on navigation lights and instruments, and check Houston TranStar or your carrier for the latest updates before you head out.
