An upper low across the central Gulf of Mexico will continue to help bring a northerly flow with dry air into the region. Expect sunny skies again today with afternoon highs in the mid 90s. Heat index values will hover around 102. That upper trough will continue on a westerly track over the weekend and eventually reach the Texas coast by Monday. As it passes south of the area, dry conditions are still expected for the remainder of the weekend. Humidity levels will rise again by Sunday with a slight chance for a shower or thunderstorm. This should be in response to more of an onshore flow on the east side of that upper trough. Expect normal summer type weather for most of next week with highs in the low to mid 90s. The cool front for the following week isn't showing up in the models as much as early runs, but still hopeful we'll see some slight changes for the last week in September. Don't fret, October is just 18 days away.
Tropical weather to our east, should remain to our east this weekend. Potential Tropical Cyclone #9 still has the potential to become Tropical Storm Humberto before reaching the coast of Florida. As of now the mass of this system is drifting northwest over The Bahamas. Tropical Storm Warnings are posted for the Bahamas, and Tropical Storm Watches are posted for Florida. The official track brings the system over Florida as a tropical storm, then curving back into the Atlantic Ocean.
The GFS Model takes it on the western side of the forecast cone, over Florida, then eastward into the Atlantic, and a loop back around to the Florida Atlantic coast for a second hit. The Euro is on the far eastern side. It's also much stronger, keeping the system offshore as a tropical storm or possibly a hurricane, eventually turning back out to sea. Regardless, Florida is going to have a rainy weekend.
Several other areas over the central and eastern Atlantic have a chance for development over the next few days. Nothing is there to threaten Acadiana, so you should be able to relax this weekend!
