New Orleans woke up warm, cloudy and sticky, with temperatures parked near 70°F at the KNEW observation and the atmosphere already loading up for trouble. Scattered showers will build through the morning, with showers and thunderstorms becoming likely by late morning into the afternoon. The most intense cells could dump brief but heavy rain, leading to localized street flooding through early Saturday.
Today and Tonight
Highs will top out around 73°F, and the chance of rain is about 90% today as several rounds of showers and thunderstorms sweep across the area.

That pattern raises a flash flood concern for parts of the region, especially the Florida Parishes and southwest Mississippi.
Northeast winds will run 5–15 mph this afternoon, then ramp up to around 15 mph with gusts near 30 mph late tonight. Boaters should expect rough going on the lakes and nearshore waters, and a Small Craft Advisory is in effect from this evening into Sunday morning, according to the National Weather Service.

If you were eyeing a run onto Lake Pontchartrain or the coastal waters, it is worth considering waiting until after the advisory lifts. On the roads, avoid driving through standing water and give yourself more stopping distance on slick pavement…
