Sunday in New Orleans is coming in hot and sticky, with temperatures hovering around 66°F and humidity near a swampy 94%. Low-lying neighborhoods are waking up to patchy fog cutting visibility, and showers with thunderstorms are likely before 1 p.m. on Sunday, March 8, 2026. The afternoon stays warm, with highs close to 80°F and pockets of heavy rain that could briefly pond on streets and in yards, as reported by the National Weather Service.
Showers And Thunderstorms This Afternoon
The early mix of fog and scattered light showers is expected to give way to a more organized band of showers and thunderstorms between about 1 and 2 p.m. Sunday, with the most intense activity lining up near and north of the I-10/I-12 corridor. New rainfall totals of a quarter to a half inch are possible, and a few stronger storms could toss out damaging wind gusts and spark localized urban flooding. Drivers should plan for erratic gusts and sudden drops in visibility during the heaviest downpours, which may slow midday and afternoon travel, according to the National Weather Service.
Foggy Mornings And Marine Concerns
Cooler nearshore waters will help spin up dense early-morning fog over shelf waters and along the lakefront, cutting visibility for boaters and early commuters. Boaters heading out at dawn should use extra caution, and drivers are advised to stick with low beams and allow more stopping distance if the fog thickens. Coastal and river interests are urged to monitor updates before launching; small craft conditions should remain manageable today, but any thunderstorms sliding offshore could kick seas and winds up a notch.
Midweek Warmth Then A Windy Shift
The warm, humid pattern hangs on into Tuesday and Wednesday, with highs pushing into the low 80s. Forecasters note that both days may approach or even slip past record highs in some spots. A fast-moving front is expected to sweep through Wednesday night into Thursday, ushering in cooler air and cranking up northwesterly winds that could gust to around 40 mph inland and blow even stronger over coastal waters. Residents and mariners should keep an eye on forecast updates and the office forecast discussion for tweaks to timing and wind impacts later in the week, per the National Weather Service.
