New Orleans woke up Friday to clear, soupy air and upper‑70s temperatures, the kind of morning where it already feels like you are walking through a wet blanket. The heat will build through the day, with readings climbing into the upper 80s and low 90s by midafternoon. Keep the umbrella within reach, too, since scattered afternoon showers and a few thunderstorms are on the table. It will feel hotter than the thermometers suggest, and forecasters are eyeing a longer stretch of unsettled, wetter weather early next week. On the road and on the water this afternoon, expect pockets of heavy rain that can knock down visibility and slow commutes.

Afternoon Storms And Weekend Heat

Showers and thunderstorms become more likely after about 1 p.m., with mostly sunny skies in the morning giving way to scattered pop‑up storms later in the day and a high near 90. A few stronger cells could briefly open up and dump heavy rain, enough to snarl the drive home, although most neighborhoods are expected to see less than a tenth of an inch overall. Forecasters say this will mark the first real heat spell of the summer, with heat index values running about 100 to 105°F from Friday through Sunday. A slow‑moving front early next week is expected to boost shower and thunderstorm coverage and raise the risk of localized flooding on Monday and Tuesday, according to NWS New Orleans/Baton Rouge.

Stay Cool And Know Where To Go

Heat safety is not optional in this kind of pattern. Hydrate often, take breaks from strenuous outdoor work during the hottest part of the day, and check on older relatives, kids, and pets who may struggle in the heat. If you do not have air conditioning at home, state officials recommend calling 311 or using city resources to track down a public cooling site. For local guidance and a list of heat relief options, head to the Louisiana Department of Health.

Tonight And This Weekend

Tonight stays mostly clear, with lows in the upper 70s and only a slight chance of any leftover showers in the early evening. Saturday and Sunday turn hotter and stickier, with highs in the low 90s inland and overnight lows holding in the upper 70s. It is a good weekend to push yard work or workouts into the morning or later evening hours. If you have outdoor plans early next week, keep an eye on forecast updates. The timing of the front will decide who ends up under the heaviest rain and which spots could see flooding become an issue.
