Sunday, June 7, is starting out warm and thick with humidity across New Orleans. Lakefront readings are already near 79°F, with dew points in the mid‑70s, so it feels every bit as sticky as it sounds. A slight chance of light rain early this morning will give way to scattered showers and thunderstorms from late morning into the afternoon, with highs topping out around 88°F. South winds stay on the gentle side, generally 5 to 10 mph, but the humidity will make it feel hotter than the thermometer lets on.
Coastal Flood Advisory Through 10 a.m.
The National Weather Service has a Coastal Flood Advisory in effect until 10 a.m. CDT for parts of the metro, including St. John the Baptist, Lower Tangipahoa, southern Livingston and upper St. Charles parishes, where minor flooding of lots, parks and low‑lying roads is possible, according to the National Weather Service. After several days of east‑to‑southeast winds, water has piled up on the western sides of Lake Pontchartrain and Lake Maurepas, leading to minor ponding. Isolated road closures could pop up in the advisory area, so if you have to travel, give yourself extra time and skip any route with standing water.
When Rain Is Most Likely
A slight chance of showers hangs on around 9 to 10 a.m., then rain and a 30 to 40% chance of thunderstorms move in through the afternoon, with the best odds roughly between noon and 3 p.m. Most spots should pick up under a tenth of an inch of new rain, but with saturated soils, any brief heavy downpour can still trigger localized street flooding.

Week Ahead
Looking ahead, expect a gradual drying trend to kick in Monday, with highs in the upper‑80s to near 90 and fewer scattered storms through much of the work week. Storm chances tick back up a bit late in the week, but overall coverage still looks lower than what we are dealing with this weekend.
How To Prepare
If you are heading out, bring an umbrella and plan for sticky, humid conditions. Budget a little extra time for commutes and stick to higher routes if you drive near lakefront or tidal‑lake neighborhoods. Steer clear of flooded streets and keep an eye on local updates if you live in any of the advisory zones.
