Louisiana – A blanket of dense fog settles across southeast Louisiana before daybreak, softening streetlights and dimming visibility to only a few hundred feet. Roadways glisten under the haze, and drivers heading toward New Orleans, Metairie, Gretna, and the West Bank will find a slow, cautious start. This early-morning murk arrives just as Thanksgiving travel ramps up across the region, and it demands patience.
The National Weather Service has issued a Dense Fog Advisory until 9 AM CST, warning that thick fog could drop visibility to one-quarter mile or less. Travel will slow on major corridors including I-10, I-610, U.S. 90, and the Huey P. Long Bridge. Use low-beam headlights, reduce speed, and allow extra space between vehicles—conditions may vary sharply from block to block.
Once the fog lifts, today turns warm and mostly sunny with highs near the upper 70s. Light south winds return, pushing humidity back into the area and setting up a stretch of quiet, almost springlike November weather. Tonight brings another round of dense fog potential, especially near swamps, waterways, and rural stretches between Baton Rouge and New Orleans.
Wednesday stays mostly sunny and warm with highs around 78. Fog may linger through mid-morning before sunshine breaks through again. Winds remain light, keeping conditions calm but allowing moisture to pool overnight.
Thursday introduces a subtle change. Models hint at the return of scattered showers late in the day or toward the evening. While no severe risk is evident yet, any small downpour could briefly lower visibility again and create slick pavement for travelers heading toward early Thanksgiving gatherings.
Friday adds a slightly higher chance of showers, with temperatures still running above average. Saturday looks partly sunny and mild, offering a useful window for errands, holiday prep, or decorating ahead of Thanksgiving week.
