Tropical weather pattern looks to remain in place across Acadiana.

Good Sunday afternoon everyone! Scattered showers and storms have developed across Acadiana this afternoon thanks to a weak tropical wave that sent added moisture our way.

The bulk of this activity will quiet down once we lose the heating of the day and temperatures will drop back into the mid 70s overnight tonight and into Monday morning.

The main setup for our weather this week will be an upper high that settles in across the southeastern U.S. and won't really move a whole lot through the course of the next several days. This will allow a couple of waves of tropical moisture to move around this high and into the Gulf of Mexico. The first of these waves moved in today and will linger into Monday, so rain chances will remain slightly elevated.

Tuesday and Wednesday we will kind of be in between the first wave and another one looking to move in from the Gulf, so rain chances will come back to normal for typical daily afternoon storms.

A second wave will move closer to the area by late week which will help to give us a slightly better scattering of those showers and storms once again. This second wave also has the attention of the NHC, so be sure to check out the tropics discussion below. Still too early to pinpoint exact rain totals and where the heaviest of the moisture will set up, but we will likely still see our fair share of rainfall throughout the week. You'll want to stay with the KATC storm team for the very latest. Normal July rain chances return for next weekend with temperatures back in the 90s. Y'all have a great week!

In the tropics: A tropical wave just north of the islands and Cuba has been given a 20% chance of development in the next 5 days as it treks into the Gulf of Mexico. Development chances remain LOW at this time, but a weak surface low pressure may develop once it enters the Gulf. Regardless of development, we are likely to see a surge of tropical moisture by late week from this system which will enhance our rain chances. Some heavy rainfall amounts are possible, but it is still too early to predict where the heaviest of the rainfall will set up. The rest of the tropics are quiet at this time.
