"Persistence" is the forecast for Acadiana at least one more day with scattered splash and dash showers and storms remaining in the forecast Wednesday, but there should be fewer storms and hotter temperatures in the offing later this week.
The persistent pattern means that hot and humid conditions will continue to precede and follow the scattered showers and storms Wednesday, but there are signs that high pressure aloft building in from the northwest should decrease the area's rain chances, thereby allowing for hotter temperatures as well.
Look for highs in the lower 90s Wednesday with heat indices near 102-104 and roughly a 40% chance of storms.
Rain chances should decrease closer to 20% Thursday and Friday allowing for more extensive afternoon heat, with highs pushing the mid-90s along with heat indices rising into the 104-108 range and continuing into this weekend.
The weekend forecast remains a little bit of an enigma with models flipping back and forth on atmospheric moisture levels.
Today's Euro model hints that there will be a break in the ridge by late Saturday opening up the door for deeper tropical moisture and the threat of showers and storms by late in the day.
Therefore, the risk of scattered storms should rise at some point this weekend, but by how much and when is up in the air...literally.
Right now the 10 Day Forecast indicates best rain chances by Saturday evening, but away from the storms it looks like our high August heat and humidity will persist well into next week, with rain chances possibly getting back to 20% range for a good part of the week.
No cool fronts are in our immediate future, nor are any tropical systems, so it's par for the course, for now.
