Louisiana – A thick, pearly fog drapes the Mississippi River this morning, softening streetlights and muffling traffic across New Orleans as the city wakes to near-zero visibility in some neighborhoods. Moist air clings to sidewalks, and beads of condensation slide down windshields as early Thanksgiving travel begins to pick up. Drivers navigating I-10, I-55, and the Causeway should expect slow-moving traffic and sudden visibility drops through mid-morning.
According to the National Weather Service New Orleans/Baton Rouge office, a Dense Fog Advisory remains in effect until 8 a.m. with visibility occasionally falling below a quarter mile. According to forecasters, fog will thin steadily by late morning as sunshine breaks through and temperatures climb into the mid-70s. Once the fog clears, winds stay light, giving residents a useful window for errands, leaf cleanup, or early holiday decorating.
According to local emergency managers, anyone traveling today should use low-beam headlights, allow extra following distance, and avoid sudden braking. As the day brightens, clearer skies return, but attention quickly shifts to a subtle pattern change early next week. Calm winds Sunday lead into a warmer Monday with highs near the upper 70s, offering mild air for early-week outdoor plans.
A broader shift may take hold by Tuesday as moisture deepens across southeastern Louisiana. While rain remains uncertain, models hint at a slow-building increase in clouds—a small Winter Tease that often precedes stronger Thanksgiving-week systems. Temperatures stay far from any Freeze risk, but muggy air may thicken again as the Gulf sends moisture north.
For now, the most immediate hazard is today’s dangerous fog. Residents should stay patient on the roads and expect improved travel conditions later this morning, followed by a warm, mostly quiet stretch through Monday.
