For those that haven’t melted away yet, find a beach to visit today as that will be the best way you can cool off this weekend. With rain chances remaining minimal and a heat advisory in effect from 10:00 am to 7:00 pm CDT, coastal communities will see heat indices reach 108F-to-113F in the afternoon and evening.

Now for hope! Though today will be blisteringly hot, tomorrow’s heat indices will recede to 100F. This reduction shows a pattern change as winds shift to northeasterly, bringing in air temperatures around 90F-to-95F. Additionally, dewpoint temperatures will fall by 10 degrees to a less tropical 65F. While still warm and muggy, these conditions will provide a mild relief through the beginning of next week.

While coastal MS/LA/AL will be partially reprieved from the brutal southeastern heatwave, temperatures are still expected to run approximately 5F above normal. According to the Climate Prediction Center, a persistent eastern high pressure system will continue to dominate, creating a southerly wind flow that brings in warmth and moisture from the Gulf of Mexico. As a result, there is a 70-to-80-percent chance of above average temperatures in the region through June 27th. The ridge is generally expected to influence the south-central US in the month of July, leading to a 50-to-60-percent chance of abnormal warmth for the Northern Gulf Coast.
