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.
