NEW ORLEANS — WWL-TV Meteorologist Alexandra Cranford

Scattered thunderstorms allowed temperatures to drop to a more reasonable range this Tuesday evening after a scorching afternoon.

Air temperatures reached 97 at the Kenner airport and at Slidell today. Heat index values soared to near 113, prompting an Excessive Heat Warning for the Northshore and Heat Advisory for the Southshore.

Most of evening rain will wrap up after sunset.

Then on Wednesday and Thursday, a front will sag near us and help showers and thunderstorms to form. That should keep temperatures down a little to low 90s and heat index values closer to 100. 

There could also be some heavy downpours and perhaps a stray strong thunderstorm with some high wind gusts – the Storm Prediction Center has placed the Northshore at a marginal risk of severe weather on Wednesday.

High pressure builds over us again Friday into next weekend, which will bring more high heat and a few spotty afternoon storms.

Thankfully, we do not have any tropical threats this week. The tropics are still quiet as dry, dusty air swirls over a huge part of the Atlantic Basin.
