Acadiana can expect a return of partly sunny skies Friday, but there will still be the risk of scattered mainly afternoon/early evening showers and storms.

Rain chances will decrease this weekend, at the expense of building high pressure and subsequently increasing mid-summer heat.

After a fair bit of early morning clouds Friday, look for intervals of sun to kick in by midday, but with the remnants of a weak surface boundary in the area, there should be a scattering of showers and a few thunderstorms for the afternoon and perhaps, lasting into the early evening.

Temperatures Friday will manage to make the lower 90s with heat indices pushing the upper 90s to 100..

Rain chances Friday will be in the 30-40% range, but should drop to 20% Saturday, and near 10% or less Sunday.

And with drier air and more sun Saturday, temperatures will likely climb to a high of 92-93 degrees with the heat index likely reach 100-102.

The upper ridge of high pressure will continue to expand Sunday engendering hotter afternoon temperatures which will likely reach the mid-90s.

High heat, humidity and heat indices accompanied by minimal rain chances will continue through mid-week with highs reaching the mid-90s accompanied by full mid-summer heat indices reaching the 104-108 degree range.

The ridge of high pressure breaks down toward the end of next week, which according to consistent runs of the European model, might allow for a shot of deep tropical moisture to run northward from the Bay of Campeche and interact with an upper disturbance coming out of the Rockies and Northern Mexico.

This could yield some locally heavy thunderstorms and rainfall by Friday…we’ll see.
