Hazy, hot and humid conditions along with suppressed rain chances remain on tap for Acadiana over the next few days while the tropics have become active...but not here.

In the near term, you may have noticed the hazy skies across the area Tuesday owing to the return of African dust.

This tropical and thunderstorm inhibiting dust will stay around at least through Wednesday, but should thin and advance eastward out of the area by Thursday.

Temperatures will continue to soar into the lower 90s over the next few days with heat indices reaching the 100-104° range.

A slightly better chance of an isolated shower may develop Friday into the weekend, but rain chances are expected to remain 20% or less.

The longer term outlook remains unclear with the GFS saying "yes" to a fall-like cool front into early next week, while the Euro model has been pretty much backing off on any significant cooling through the next 10 days...so don't set your expectations too high on any summer heat relief for now.

Meanwhile, the tropics became more active Tuesday with two new named storms.

Tropical Storm Nana looks to become a hurricane prior to threatening Belize, Mexico & portions of Central America Thursday, while the newly minted Tropical Storm Omar off the U.S. East Coast is expected to be short-lived and a lonely Atlantic system.

Another wave closer to Africa has a 50% chance of development this week into the weekend.

While there are no current threats to Gulf of Mexico at this time, that could certainly change into the the second week of the month (and beyond) with some sort of development favored by the longer range models and outlooks for the Southwestern Gulf, perhaps the Caribbean and certainly in the Atlantic.

Conditions could become quite conducive for increased tropical activity later this month and it appears there could be more potential U.S. threats in the cards.
