New Orleans woke up on Saturday, June 20, 2026, to clear skies, thick humidity and an early-morning slap of summer, with temperatures around 79°F and a dew point near 77°F. Translation: it felt muggy before coffee, and it is only going to get stickier as the sun climbs.
Afternoon Heat and Storm Risk
Forecasters say showers and thunderstorms are likely after 11 a.m., with a high near 90°F and south winds around 5 to 10 mph. Most spots will see light rain, but any storm that really gets going could drop very heavy downpours in a hurry.
A Heat Advisory is in effect from noon to 6 p.m. CDT on Saturday, June 20, 2026, with heat index values expected to push into the upper 100s (roughly 105 to 108°F). That makes extended time outside a risky proposition, especially for anyone working or playing hard in the sun.
Stronger storms this afternoon could also bring gusty winds, isolated tornadoes or waterspouts and very heavy rain that may trigger localized flooding, since many neighborhoods are already saturated. Forecasters expect the pattern to stay hot into early next week, with storm coverage shifting later in the week, according to NWS New Orleans.
Heat Relief and Safety
If your air conditioning is unreliable or nonexistent, the city maintains a list of cooling centers and heat-relief options. You can sign up for emergency alerts by texting NOLAREADY to 77295 or call 311 to find out what is open near you.
During the advisory, try to avoid strenuous outdoor work during peak heat, drink plenty of water all day instead of waiting until you feel thirsty, and check in on older neighbors, young children and pets who may struggle in the heat. For specific locations and preparedness tips, visit NOLA Ready.
Where Storms Could Be Strongest
Outflow boundaries already in the area are helping storms bubble up. The northern tier of parishes along the Louisiana and Mississippi line is most favored this morning, with another corridor possible from north of Baton Rouge down the Mississippi River into the metro area this afternoon.
Because some storms can crawl rather than race through, expect bursts of intense rain that quickly pond on low-lying streets and slash visibility. If you have afternoon plans, build in a quick indoor backup. The strongest cells can flare up, dump rain and fizzle in short order.
Looking Ahead
Looking beyond today, expect hotter, drier conditions Monday and Tuesday, with highs in the low 90s and fewer afternoon showers as a stronger ridge builds overhead. By midweek, that pattern should relax, allowing scattered afternoon storms to return Wednesday through Friday, along with another chance of heavy downpours and gusty winds.
If you are scheduling outdoor events later in the week, it is worth checking each morning’s forecast so you are not caught off guard by a surprise storm window.
