While more pleasant temperatures are on the way to Acadiana Friday into the weekend, unfortunately it appears that we will have to continue to monitor the Gulf of Mexico for potential development in the days ahead.

In the near term, after another day of temperatures near 90° under a sun and cloud mix Thursday, a surge of drier and slightly cooler high pressure will advance toward the area Friday.

While not a sharp cool front, the air-mass on the way to Acadiana should bring our daytime highs down into the mid-80s into the weekend with overnight/morning lows dropping into the mid-upper 60s.

While there should be plenty of clouds with the cooler temperatures Friday, look for more sunshine and just a pleasant early fall-like weekend!

See the KATC 10 Day forecast for the latest.

Meanwhile, there's no rest for the weary in the tropics...

After battering portions of Mississippi, Alabama and the Western Florida Panhandle as a category 2 hurricane with 105 mph winds and more than 20 inches of flooding rain, Tropical Storm Sally continues to slowly weaken while moving northeastward, eventually passing through Georgia and the Carolinas producing more flooding rainfall along the way.

Elsewhere, on top of a system emerging off of the African Coast with a 70% chance of development, the National Hurricane Center (NHC) is continuing to issue advisories on Tropical Storm Vicky and more powerful Hurricane Paulette.

While Vicky is expected to fade away, Paulette could threaten Bermuda by this weekend as a formidable storm...some models are also hinting that Paulette could come rather close to portions of New England several days afterward.

But closer to home, the NHC continues to monitor and broad area of low pressure (designated as 91L) in the Southwestern Gulf of Mexico, giving it a 70% chance of development into a depression or perhaps a tropical storm by this weekend.

This system has the potential to meander in the Gulf for days, and will eventually impact someone along the Gulf Coast...meaning anywhere from Mexico to Florida will have to watch this one.

And as always with a developing system, no models (whether it's the Euro or GFS, or specific hurricane models) can be trusted at this time.

It is not out of the realm of possibilities that this system could make landfall somewhere along the Gulf this weekend...or maybe even waiting until the following weekend, or sometime in between...and a storm of hurricane intensity is not out of the question.

The last name in the 2020 hurricane list this year is "Wilfred"...then it will be on to the Greek alphabet starting with Alpha and Beta etc.

2020 will also go down in the record books as the soonest the regularly scheduled names have been all used...not a surprise on the number of storms this season, but so many at this mid-point of the season.

To date, there have been four U.S. hurricane strikes: Hanna, Isaias, Laura and now Sally.
