BATON ROUGE, La. (WAFB) - High pressure will remain in control of the local weather right on through the weekend.

A weak cold front will drift into the area Friday, but you really won’t notice it. Temperatures may take a one or two degree dip. Expect mainly dry weather through the rest of this week. We might see a couple spotty coastal showers Friday and Saturday afternoons.


Our next strong cold front is set to arrive Sunday into Monday. Only a few showers will accompany this front. The front will help deliver temperatures more suitable for late September with highs going from the mid 90°s before the front to mid 80°s behind the front. This could front will work into the area as a trough develops across the Eastern half of the U.S. This trough will be important to us related to the tropics.


The hope is that the trough will help push whatever becomes of Invest 98-L away from Louisiana by the middle and end of next week.

Dr. Steve will provide a live update on the tropics, including the system in the Caribbean that is expected to move into the Gulf of Mexico next week.

The tropics are quite active with Major Hurricane Fiona expected to brush past Bermuda on its way towards Nova Scotia and Newfoundland Canada. Tropical Storm Gaston continues to twist around the Northern Atlantic and may sweep past the Azores. 3 other tropical waves are being tracked by the National Hurricane Center for potential development.


The one we are paying most attention to remains Invest 98-L in the Eastern Caribbean. Invest 98-L is forecast to become a tropical storm and possibly a hurricane as it moves towards the Gulf of Mexico by the beginning of next week. The environment in the Western Caribbean is currently forecast to be very suitable for development. While the ultimate potential U.S. destination is still unknown, it does look like the Eastern half of the Gulf of Mexico is most at risk. There is still plenty of time to monitor the evolution of this system.
