Rain chances will decrease across Acadiana Wednesday as drier more stable air will advance into the region. Unfortunately, this means our temperatures will be heading back into the lower 90s.
As the upper level low pressure near New Mexico continues to retrograde to the west, high pressure will advance southwestward from the Eastern U.S. helping to lower local rain chances.
Showers and thunderstorm activity won't be completely eliminated, but rain chances should be closer to 20-30% Wednesday (and perhaps Thursday) as opposed to the 60% coverage much of the area has experienced over the last couple of days.
This pattern may continue into Thursday but another upper level low over the Bahamas/Florida will begin to track west-northwestward by the end of the week into the weekend shuttling in a subtle increase in tropical moisture.
Rain chances will likely trend back closer to 30-40% for the weekend, but away from any storms it will continue to be hot and humid with highs persisting in the lower 90s...typical July weather for Acadiana.
In the tropics, quiet conditions for the most part prevail. Upper lows in the Southwestern Gulf and the one by Florida are the most active areas in the tropical basin through the Atlantic. These systems are not expected to generate any significant surface low pressure at this time.
