NEW ORLEANS — WWL-TV Morning Meteorologist Dave Nussbaum

The upper-level low and trough of low pressure at the surface, now Invest 98L, is getting better organized in the far NW Gulf of Mexico today. This system has a chance to develop before it moves inland over Texas tonight. It will send us more clouds today with spotty showers and a few storms. We will see more sunshine peaking through the clouds today, so it will be hotter with highs in the lower 90s. 

Invest 98L will move into Texas by Wednesday and it will likely stall there with heavy rain and flooding. A large area of high pressure will build toward us from the East Coast tomorrow and it will stay over the Deep South through Friday. This will make it mostly sunny, hotter and humid. Louisiana will be on the southern edge of it, so we could still see an isolated shower or storm pop-up. High temperatures will climb into the mid 90s. 

Weekend Outlook: The ridge of high pressure will be just east of Louisiana, so our weather will not change. Saturday and Sunday will be partly cloudy, hot and humid with a slight chance for a shower or storm. High temperatures will be in the lower 90s. 

Tropics: Invest 98L remains over the NW Gulf of Mexico just off the Texas Coast. There is a chance for it to develop into a weak tropical system before it moves inland into Texas tonight. 

Hurricane Humberto continues to grow in size and it is expected to strengthen today. It is located over the warm waters of the Gulf Stream and far off the SE U.S. Coast. The hurricane has winds of 90 mph, but it is expected to strengthen into a Cat. 3 hurricane by Wednesday as it moves just north of Bermuda. Then it will turn NE and head out into the Atlantic as it weakens. 

Invest 97L is located out in the central Atlantic. It has a high chance to become a tropical depression or storm the next few days. It is forecast to stay out a sea and just stay north of the Lesser Antilles in the next 7 days. This is not a threat to the U.S.
