As the weekend approaches it appears that the prospects of scattered showers and storms will increase Friday into the weekend.
A series of weak disturbances and increased tropical moisture over the Southeast U.S. including the Eastern Gulf through Bahamas, will travel westward toward Louisiana over the next few days engendering a better chance of mostly daytime showers and thunderstorms through Sunday.
In addition, an upper level trough of low pressure will approach from the north adding instability to the atmosphere making clouds and scattered showers the dominant features this weekend.
Activity will be primarily during the day Friday into the weekend with activity possibly lasting a little longer into the early evening hours Saturday and Sunday.
Rain chances are expected to be in the 40% Friday and near 50-60% this weekend, dropping back down to the 40% range or less Monday.
Highs this weekend will likely be in the mid-upper 80s with a few spots capable of touching 90, depending on shower and cloud coverage.
It appears that Acadiana should see drier conditions for the middle part of next week, but tropical moisture will be surging back northward later in the week as perhaps a bonafide frontal system approaches for next weekend.
Rain chances as a result will likely be on the upswing again in time for next Friday into the weekend.
We could see briefly cooler conditions following next weekend's front but this system could also provide a catalyst for tropical Gulf development thereafter.
