More high heat is on tap for Acadiana Tuesday with temperatures topping out in the mid-90s and heat indices reaching 105-110°...but a break could be coming.

There will be a very slight chance of a late afternoon or early evening shower or thunderstorm Tuesday, but a weakness in the ridge of high pressure should allow for better prospects of scattered storms come Wednesday and especially Thursday afternoons.

Highest heat indices Tuesday will be across the northern portions of Acadiana, with the National Weather Service maintaining a Heat Advisory for all of Acadiana from 11 am through 7 pm.

The chance of a cooling shower or thunderstorm Tuesday will be near 10-20%, and up to 20-30% Wednesday and near 40% Thursday.

And with a better chance of afternoon storms, daytime highs will nudge closer to the lower 90s Wednesday and Thursday,

Atmospheric moisture levels should drop again Friday into Saturday, leading to more sun and fewer showers with temperatures pushing back into the mid-90s.

Thereafter, it appears that deeper tropical moisture associated with a slow moving tropical wave will move in early next week, finally leading to substantial rain chances and capping temperatures near 90° or below for a few days.

The tropics are eerily quiet across the Atlantic Basin and much of the globe right now, but that is expected to change toward the end of the month when more robust tropical waves coming off of the African Coast are expected.

And in Monday evening celestial news: barring any cloud cover Acadiana should have an excellent view of the International Space Station flying directly overhead at exactly 9:48 pm!

It will be visible first in the southwest sky at 9:45 pm moving toward & disappearing in the northeast sky.
