New Orleans eased into Monday, March 9, 2026, under a gray lid of low clouds and sticky air, with dense fog hugging the lakefront and pooling in low-lying neighborhoods for the morning commute. Temperatures started in the upper 60s to around 71°F and are expected to jump into the low 80s by midafternoon, with a slight chance of showers or isolated thunderstorms later in the day. Travel could be sluggish early, but where the sun breaks through, the fog should thin out by mid- to late morning.
Foggy Morning Commute
A Dense Fog Advisory issued March 8 remains in effect through 9 a.m. CDT Monday, March 9, 2026, with visibility dropping to one-quarter mile or less in spots, which could make driving hazardous, according to the National Weather Service. Drivers are urged to stick with low-beam headlights, ease off the gas, leave extra stopping room, and skip cruise control on the damp roads. Bridges, the Lake Pontchartrain Causeway, and riverfront routes are the most likely trouble zones for reduced visibility this morning.
Afternoon Showers and Heat
Once the fog mixes out, partly sunny skies should help push highs to around 82°F this afternoon with light south winds of 0 to 10 mph. There is a slight chance of showers or a few thunderstorms between 1 p.m. and 5 p.m.; any storms that pop up should be brief but could still pack gusty winds and a quick burst of heavy rain. If you have outdoor plans late in the afternoon, it is smart to have a nearby spot where you can duck under cover.
Midweek Front Could Bring Strong Gusts
A cold front is projected to sweep through Wednesday night into Thursday, bringing a higher chance of showers and thunderstorms along with the potential for stronger gusts overnight. Winds could rise to 10 to 20 mph with gusts up to 35 mph from Wednesday night into Thursday, and temperatures will drop behind the front, with highs settling in the upper 60s on Thursday. Boaters and anyone planning to be on the water should keep a close eye on the forecast for increasing winds and rougher conditions.
What To Watch
Keep weather alerts enabled for early departures and check local traffic feeds if you have to be on the road in the next few hours. For more context on the recent run of fog, storms, and early-season heat, see our March 8 update: warm storms and fog hit New Orleans.
