NEW ORLEANS — WWL-TV Morning Meteorologist Dave Nussbaum

A trough of low pressure remains over us today and when you combine that with the sea breeze, they will help to set off scattered showers and storms. The overall coverage of rain will be less than what we saw on Wednesday. We will see some sun before the storms develop, so high temperatures will be in the lower 90s. Expect plenty of clouds tonight with spotty showers. Lows will be in the 70s. 

A tropical wave and mid-level low pressure in the western Gulf will start to impact our area on Friday. Fortunately, it is not expected to develop into a tropical system.  However, deep tropical moisture will move over us during the day and it stays over us all weekend. The forecast models keep the low out in the Gulf on Friday, but it will be close enough to set off scattered showers and storms with heavy rain. We could pick up 1-2"+ inches of rain, so flash flooding and street flooding will be possible. The rain will continue into Friday night too.

Weekend Forecast: The low will be right along the Louisiana Coast to just inland on Saturday and Sunday. This will continue to bring us scattered storms with more heavy rain. The flash flood threat and street flooding will continue all weekend. Rain totals between Friday and Sunday could be around 2-5" with the higher amounts along the coast. Make sure you stay weather aware and keep rain in your plans all weekend.

In the tropics: The tropical wave moving our way for Friday is not expected to develop. 

Chantal has weakened into a tropical depression. It remains in the far north Atlantic and is not expected to affect land. It is expected to dissipate on Friday. 

There is a disorganized cluster of showers and storms over the Bahamas. They will move to be just off the east coast of Florida by this weekend. Then they will curve NE and stay away from the Carolina Coast. There is just a low chance for development during the next 5 days. This is not a threat to the Gulf.
