The ridge of high pressure that has been bringing typical summer weather to Acadiana over the last several days will retrograde farther to the north later this week opening the door for better rain chances for the area.
This will also induce a deeper east to west flow of tropical moisture across the Northern Gulf States allowing for not only a better chance of storms, but more than likely an earlier onset of daily activity starting Friday.
Risk of showers and storms should increase to 50% or better Friday into the weekend with locally heavy downpours and frequent lightning possible in some of the storms.
Although the risk of organized severe weather should be low, there is usually a very slight risk of damaging down-burst winds and the possibility of tropical funnels in this type of pattern.
Daytime highs as a result of the showers and storms will be closer to the upper 80s to lower 90s for most of Acadiana Friday into the weekend.
Better than normal rain chances may continue for most of the days next week as a couple of tropical waves entering the Gulf may keep the tropical plume of moisture going across the area.
