Another hot and humid day is on the horizon. Early sunshine will promote a quick warmup into the lower 90s. By midday, with thermometers in the low 90s, convective cloud development could produce an isolated shower or thunderstorm-but only about 30% of the area in Southeast Louisiana and Southern Mississippi will receive rain today. The top out temperature will be near 94°.
The overnight hours will remain sticky and sweaty. Clouds will break but thermometers will struggle to leave the upper 70s.
There are two unorganized clusters of showers and thunderstorms approaching the Lesser Antilles. The tropical wave slightly farther west, Invest 96L, is given a 50% chance of development over the next 5 days by the National Hurricane Center. IF this system can survive harsh upper level conditions and dry air in the Caribbean Sea, there are a few forecast models that advance it towards the Gulf of Mexico by the middle of next week. More than a week out, there is very little skill in forecast models-especially with tropical systems, however anything in the tropics warrants attention as we enter the peak of hurricane season. As always, stay prepared.
The second wave is looking even less impressive as of Wednesday Morning and the National Hurricane Center puts its chances at 20% of development over the next 5 days.
