Saturday, May 30, New Orleans woke to clear, humid skies and mid-70s temperatures at the airport this morning, the kind of start that tells you the air-conditioning is about to earn its keep. Mostly sunny conditions will push highs near 88°F today, with light southwest breezes and humidity making the afternoon feel hotter than the thermometer lets on.
A broad ridge of high pressure keeps the Gulf South on the drier side through the weekend, but temperatures climb into the upper 80s to near 90°F from Sunday, May 31 through Tuesday, June 2, with heat indices creeping toward 100°F. Most neighborhoods are expected to fall into a moderate heat-risk category, and a few inland spots could see more serious heat stress, so frequent shade breaks and plenty of water are your friends. According to the National Weather Service, this early-season warmth could push heat impacts beyond the most vulnerable groups.
Afternoon Showers Return Midweek
There is only a small chance of brief, pop-up, daytime showers Sunday afternoon, May 31, but scattered showers and thunderstorms become more likely Monday afternoon, June 1, and again Tuesday afternoon, June 2. Any storms Monday through Tuesday could produce brief heavy downpours and occasional gusty winds, although widespread severe weather is not expected.
Flooding Upstream
Forecasters note river flooding will continue in Pearl River County and the Mississippi coastal basins as water drains from heavy rainfall earlier in the week. Residents in low-lying areas north and east of the metro should be cautious around swollen creeks and avoid driving through standing water.
Boaters And Commuters
A light onshore flow will keep Gulf waters relatively calm through Tuesday, with winds around 5 to 10 knots and seas under 2 feet. A weak front Tuesday night may briefly shift winds offshore and allow seas to climb to 2 to 4 feet by Thursday as a Gulf low develops. If you have plans on the water, check the latest marine forecast and local tide or gauge readings before launching.
Heat Relief And What To Do
If the humidity has you hunting for relief, the city’s heat-relief map lists public cooling locations and hydration stations. Check NOLA Ready for hours and sites, and stick with simple precautions: drink water, limit heavy exertion during the hottest hours, and check on neighbors without air conditioning.
Bottom line: Expect highs near 88 to 89°F through Tuesday with a low around 76°F tonight, and scattered afternoon storm chances returning early next week. Plan outdoor activity for the cooler morning hours and keep an eye on forecasts for any changes to river or marine conditions.
