Louisiana greets the morning wrapped in thick fog, with streetlights glowing softly and brake lights fading fast along major corridors. Visibility drops quickly across southeast Louisiana, making early holiday travel slower and more stressful than usual.
According to the National Weather Service in New Orleans, a Dense Fog Advisory remains in effect through mid-morning. Visibility may fall to a quarter mile or less across metro New Orleans, Baton Rouge, and much of southern Mississippi. Low visibility creates hazardous driving conditions, especially along I-10, I-12, and the Causeway.
Temperatures remain mild for late December, holding in the upper 60s to near 70 today. Fog may redevelop again early Sunday, particularly near waterways and low-lying neighborhoods. Drivers should use low-beam headlights and allow extra stopping distance during the morning hours.
Attention shifts Sunday night as a weather system approaches. Clouds thicken, and scattered showers become more likely into the evening. Wet roads could affect end-of-weekend travel, especially for those returning home after holiday gatherings. Winds begin to turn northerly behind the system.
That shift opens the door for colder air. By Monday night, temperatures fall into the mid-30s, then dip closer to freezing by Tuesday morning. Any lingering moisture on bridges or elevated roadways could freeze, creating isolated slick spots during early drives.
Looking ahead to New Year’s Eve on Wednesday, conditions trend drier with cooler air in place. Morning lows stay chilly, while afternoons recover into the lower 60s. New Year’s Day appears mild but starts cold, a reminder that winter is slowly tightening its grip.
Plan extra time if traveling this morning or late Sunday night. Fog and changing temperatures can catch drivers off guard. Are you seeing dense fog where you are right now?
