Acadiana should see another good chance of scattered tropical showers and thunderstorms Wednesday, but drier, more stable air will reduce rain chances starting on the 4th, and it will only get hotter into the weekend.
Deep tropical moisture will continue to feed out of the Gulf of Mexico into Louisiana Wednesday with some locally heavy downpours possible, on top of perhaps even a few funnel clouds as storms get going by mid-morning.
Rain chances will be in the 50-60% range Wednesday with prime-time for storms any time from the morning through the mid-afternoon hours...activity should diminish into the evening.
Temperatures Wednesday will likely stay on the cooler side of 90 degrees, so enjoy it, as the heat will begin to come on later this week into the weekend.
A sub-tropical ridge of drier, more stable air will actually follow the tropical moisture out of the Gulf Thursday, reducing rain chances to 20% or less, and allowing temperatures to climb into the low-mid 90s.
Heat indices on the 4th will likely climb to the 102-16F degree range...but wait, there's more...
The ridge of high pressure will take up residence right over Louisiana Friday into the weekend, reducing rain chances closer to 10% at least through Saturday, but more importantly allowing for a hotter northwest to west wind.
This means temperatures will climb into the mid-upper 90s into the weekend with heat indices pushing the unbearable range of 105-110F...so stay hydrated and take breaks from the heat!
The longer range pattern gets a little more interesting with a frontal trough sagging toward the Northern Gulf Coast by mid-week. While highest rain chances will stay east of us for a few days, they should be eventually increasing for Louisiana too.
In fact, this feature may have to be watched more closely mid-late next week as there is the possibility of a disturbance with incredibly high tropical moisture content developing and meandering in the Northern Gulf...impacts, if any and where, are yet to be determined.
