WWL-TV Meteorologist Dave Nussbaum

It is a mostly cloudy and muggy start to this Tuesday with scattered showers and a few thunderstorms for the morning commute. Watch out for some heavy rain at times. Temperatures are in the 70s. 

The upper-level wave will move across the area this morning and afternoon. This will help to set off scattered showers and storms mainly in the morning hours. Then we will have fewer storms through the afternoon and evening. Any storm could be strong with gusty winds and heavy rain. High temperatures will be near 90. Tonight will become partly cloudy and muggy with lows in the mid to upper 70s. 

A drier day is on tap for Wednesday with partly cloudy skies and only a slight chance for a stray shower or storm. It will be hot and humid with high temperatures in the lower 90s. It will feel like the upper 90s. 

Another upper-level wave will move across the Deep South on Thursday. It will help to set off scattered showers and storms with the sea breeze. The coverage will be less than today due to the wave being father to the north. High temperatures will stay in the lower 90s. 

A ridge of high pressure, currently over Bermuda, will build to the west into the eastern Gulf of Mexico starting on Friday. We will be partly cloudy, hot and humid with only a slight chance for a shower or storm. High temperatures will be in the lower 90s and it will feel like the upper 90s. 

Weekend Forecast: The ridge of high pressure will sit over the eastern Gulf all weekend. That means we will be partly cloudy, hot and humid each day. A stray storm is possible, but most of you will stay dry. High temperatures will make it into the mid 90s, especially on Saturday.  Find ways to stay cool all weekend!

Tropical Update: No tropical activity is expected in the Atlantic Basin this week.

Mississippi River: The Mississippi River crested over the weekend and is now finally falling upriver. The crest at Red River Landing was just below the trigger point for the opening of the Morganza Spillway – so it looks like it will not be opened this year after all. Here in the New Orleans area, the river is forecast to remain high but near steady just below flood stage through the end of June.
