The chance of scattered showers and some strong storms will be possible for Acadiana through Wednesday evening with the possibility of more heating-induced storms Thursday.
The combination of high pressure ridging to our north with a deepening tropical system Arthur along the East Coast should help to bring drier more stable air to the region just in time for the holiday weekend.
Rain chances should drop to 20% or less for Friday the 4th, and will be in the neighborhood of 10% or less this weekend.
The bonus with the drier air, will be reduced heat indices for Acadiana and more than likely overnight lows becoming more pleasant for the weekend....in the vicinity of the upper 60s to lower 70s.
Look for highs closer to the lower 90s this weekend.
Heat and humidity will gradually build back into the region next week with a slug of tropical moisture (and higher rain chances) coming from the Gulf of Mexico for the end of the week into the following weekend.
In the tropics, Arthur off the Florida Atlantic Coast was very close to becoming a hurricane Wednesday afternoon and will likely intensify to a Category 1 storm Thursday.
Arthur will likely to graze Coastal South Carolina Thursday & have a greater impact on the Outer Banks of North Carolina Thursday night into Friday as a Cat 1 hurricane with NHC estimated 85mph winds.
The storm should miss the big metro areas of the Northeast but could be very close to a hurricane for Novia Scotia Friday night/Saturday.
