NEW ORLEANS (WGNO) – Labor Day will bring plenty of heat to the area, but there will also be a chance for a few thunderstorms this afternoon and evening.
We’ll start the day with a mix of sunshine and clouds, with temperatures quickly climbing into the lower and middle 90s. The bigger concern will be the humidity, with heat index values expected to reach around 108 to 112 degrees across much of southeast Louisiana and southern Mississippi. A Heat Advisory is in effect for portions of the area from late morning through this evening.
Scattered showers and thunderstorms will develop this afternoon, with the greatest coverage likely closer to the coast and south of I-10. Most locations will stay dry, but any storm that develops could produce a strong wind gust, frequent lightning and a quick burst of heavy rain. The overall severe weather threat is low, although an isolated damaging downburst cannot be ruled out. Slow-moving storms could also produce localized street flooding, particularly where storms repeatedly move over the same location…
