An incredibly stagnant weather pattern has been building across south Louisiana, so changes in your day to day weather will be very little.
Just offshore an upper level disturbance is retrograding westward which will keep widely scattered showers and thunderstorms in the Gulf of Mexico.
Closer to the surface winds will be predominantly out of the south and will be pumping moisture into the atmosphere accomplishing two things.
The first will be the chance for isolated showers in the afternoon for basically the rest of the weekend and the work week.
The other will be a noticeable increase in humidity which will be driving the heat index back to the triple digits through the extended forecast.
Adding to the heat will be the development of a ridge of high pressure that by mid week will be centered more or less over Louisiana.
As the ridge builds temperatures will be reaching up to get to the mid 90s, and with a southerly wind prevailing the heat index will be closer to 105.
The way it's shaping up we could see one of the hotter weeks we've seen so far this summer, with the only heat relief coming in the form of a few isolated afternoon showers (if you're lucky enough to get one).
