In the absence of shower & thunderstorm activity across Acadiana Wednesday, hotter temperatures and heat indices were observed, and this trend will very likely continue into the weekend.
A building and bridging area of high pressure from Texas to the Gulf of Mexico will allow for hotter days ahead with heat indices climbing to very uncomfortable levels during the height of afternoon heating.
After a morning start with temperatures barely below 80° look for a hazy, hot and humid day with temperatures pushing into the lower 90s for our Thursday.
Heat indices will rise to 100-105° during the afternoon, with little prospect of a cooling afternoon shower at 10% or less.
Little change as anticipated Friday and into the weekend other than afternoon temperatures peak a little higher with readings likely to rise into the mid-90s.
Heat index values will likely push the 105-110° range into the weekend, with the possibility of some National Weather Service-issued heat advisories a possibility later this week and/or into the weekend.
Rain chances will stay near 10% or less through Saturday but could perk up a little during the latter part of the afternoons Sunday and Monday as some moisture and instability drops southward into the region...at this point however, rain chances won't be too terribly high, closer to 20-30% with best odds of some storms likely over toward Eastern Louisiana.
More high heat is anticipated for much of next week with rain chances likely staying low until the latter part of the week when a tropical wave and or an upper disturbance reach the Gulf next Thursday/Friday.

Meanwhile in the tropics, per the National Hurricane Center, "a broad area of low pressure...near eastern North Carolina is expected to move northeastward near or just offshore of the North Carolina Outer Banks on Thursday, and then turn north-northeastward and move along the mid-Atlantic coast Friday.
Environmental conditions are expected to be conducive for development, and a tropical or subtropical cyclone is likely to form within the next day or so.
Regardless of development, the system is expected to produce locally heavy rainfall that could cause some flash flooding across portions of eastern North Carolina, the coastal mid-Atlantic, and southern New England during the next few days. Gusty winds are also possible along the North Carolina Outer Banks through Thursday and along the mid-Atlantic and southern New England coasts Friday and Saturday."
Elsewhere, it remains quiet across the rest of the Atlantic Basin, but a robust tropical wave was noted emerging off the African Coast.
