Thursday will start out cloudy and rather humid. Most of the showers and storms that developed Wednesday have diminished overnight. Expect clouds to hang on today, with somewhat warm and humid conditions into the afternoon. A bit of an upper wave will move north of the region today. This should help to spark some showers and thunderstorms. The air mass is already relatively unstable, and moisture is there. This disturbance, combined with daytime heating, should get enough lift to see a pretty good coverage of rainfall by early this afternoon. Storms will be widely scattered, similar to what we see in the summer time. Afternoon highs will reach low to mid 80s.
Rains will diminish again overnight as we lose the daytime heating. Friday will be a general repeat, with scattered showers and storms developing with the daytime heating. Highs will again reach the mid 80s for highs. Models this week have shown another upper low, being cut off from the main flow, and stalling over parts of the mid south. This has advertised a rainy weekend. But recent models are backing off on this solution, so rain chances may be slightly lower by Saturday. Expect a few afternoon storms with highs in the mid 80s.
On Sunday, the unsettled weather should return with a pretty good chance for rain. Highs will reach the mid to upper 80s, with lows near 70. Next week is starting to look more like summer. Afternoon highs may reach 90 degrees before week's end.
Although hurricane season doesn't start until June 1, occasionally we'll see a preseason storm or subtropical storm. An area of rainfall and low pressure near the Bahamas and southern Florida is forecast to move northeastward into the Atlantic Ocean this weekend. The National Hurricane Center is hinting that there's a 70% chance for some development. This is not a threat to Acadiana.
