While Tropical Storm Chantal continues to race through the Caribbean, Acadiana's weather remains relatively tranquil outside of the typical scattered afternoon storms.
There will be little change in the pattern Wednesday with hot and humid conditions along with the risk of a few scattered afternoon showers and thunderstorms.
Rain chances should increase for the area Thursday as a weakening frontal trough approaches from the north. The same trough should bring drier more stable air to the region Friday into Saturday helping to lower the rain chances for these days.
This same feature will likely interact with Chantal toward the weekend, initially keeping the system well to our east. Long range models however do attempt to push an upper low and some tropical moisture westward across the Northern Gulf of Mexico mid-late next week...whether this occurs or not remains to be seen.
As of late Tuesday, Tropical Storm Chantal was sporting 65mph sustained winds. Chantal continues to race to the WNW at 26mph which is quite fast for a well-developed tropical storm.
Chantal will likely threaten Hispaniola Wednesday and then migrate and likely slow, in the Bahamas by Friday.
The National Hurricane Center forecast for Chantal brings the system close to the Eastern Florida Coast Saturday and the toward South Carolina Sunday, keeping the system a tropical storm due to relatively unfavorable upper winds this weekend.
Chantal could be close to hurricane strength prior to Hispaniola landfall, but will likely weaken significantly will crossing the island.
