?Fair skies will start your Thursday morning, with cloudiness quickly taking over by late morning. Showers and thunderstorms will be more likely today as plenty of moisture is in place, and weak leftover outflow boundaries from overnight storm systems will drift across the area. It won’t take a lot of daytime heating to get things going. Expect some storms to develop along the coast this morning, and the rest of Acadiana will follow through this afternoon.
Storms will be able to produce healthy rainfall amounts. A few areas that get under slower moving storms could easily pick up several inches of rain in a short period of time. Therefore, brief street flooding could be a possibility. Rains will linger into the afternoon and early evening hours before tapering off overnight. Additional moisture will be in place for Friday, so expect more of the same. At least temperatures will be lower with highs approaching 90 degrees, then cooling with the afternoon rains.
Over the weekend, a tropical wave will drift westward over the Gulf of Mexico. No development is expected, but it will through plenty of moisture northward toward Acadiana and southeast Texas. Rain chances will be higher over the weekend, with heavy rainfall totals expected over southeast Texas and extreme southwest Louisiana. Because of a tighter pressure gradient over the Gulf of Mexico, tides may be above normal, and winds and seas will be rough.
