A change in the pattern is underway for Acadiana with increasing clouds and humidity expected in the near-term, and eventually a good chance of much needed showers and storms by Friday.
High pressure at the surface continues to slide eastward across Florida opening the door up for an increased southerly flow from the Gulf of Mexico across Acadiana.
This will allow for more late night/early morning clouds to develop for Wednesday morning...but Wednesday should still be a pretty nice day with partly cloudy skies, breezy southeast winds and temperatures rising into the mid-80s.
The humidity will also be on the upswing with more uncomfortable conditions likely for the rest of the week and into the weekend.
A large upper trough of low pressure will advance through the SW U.S. and the Rockies Thursday ushering in deeper moisture which will translate to mostly cloudy skies for Acadiana along with the chance of a few scattered showers and possibly a thunderstorm.
The main energy from this system will arrive to the Western Gulf Coast and Louisiana Friday while moisture continues to increase.
This will lead to a good chance of showers and locally heavy thunderstorms Friday into Friday night with rainfall potential in the 1-2" range at the very least through Saturday morning.
While it is not clear at this time, moisture from a tropical disturbance off of the Western Mexican Coast Tuesday may get entrained into the system that will approach the region Friday so rain potential and amounts could be even higher.
Models vary on solutions past Saturday morning with somewhat lower rain chances for the rest of the weekend.
The surface front with the Friday system should stall just to Acadiana's north over the weekend...allowing for warm and humid conditions to persist into next week...and it will also feel that much closer to summer!
The pattern change and better rain chances will be welcomed to the area as much of Acadiana has recently been moving into moderate drought status.
