Intense August heat plus a few afternoon downpours on Tuesday

The chance for rain will increase a little Wednesday through Friday

NEW ORLEANS — We have intense heat and humidity on this Tuesday afternoon - that's no surprise, as we're in the hottest part of the year for New Orleans. 

A few afternoon and early evening downpours are likely to form. A couple of these could bring some heavy rain. Any rain should end by about 7 p.m.

Rain chances increase a little to about 60 percent Wednesday through Friday thanks to a broad trough of low pressure plus added Gulf moisture. These things will make it more likely to get some scattered downpours mainly in the afternoons. A few of these could dump a quick couple of inches of rain over the areas they happen to set up. We'll have to watch for some localized street flooding under the heaviest storms.

This weekend the trough of low pressure moves away from us, and we return to a typical 30-40 percent chance for scattered afternoon storms.

Eye on the Tropics: We are tracking a tropical wave (Invest 95L) way out in the middle of the Atlantic between Africa and the Windward Islands. It continues to get better organized and could become a tropical depression or storm in the next day or two as it moves to the west. However, it will have unfavorable conditions to develop, or sustain its strength, by the end of the week as it runs into stronger wind shear by the Windward islands. 

There is another tropical wave just off the coast of Africa. Forecast models show this could develop into a low over the next few days in the middle of the Atlantic Ocean.

Elsewhere...the rest of the tropics remain quiet.
