Heat index could reach 115 on Thursday

CHARLESTON, SC (WCSC) -

Another day of sweltering heat and humidity will return for Thursday as the Deep South and the Lowcountry remain in the grip of this oppressive heat wave that has plagued much of the central and eastern part of the country.

With plenty of sunshine Thursday, highs will reach back into the upper 90's to low 100's inland. Factor in the high humidity values and the heat index will soar to 110 to 115 degrees or more so heat advisories are in effect.

There is a chance that the heat advisory is upgraded to an excessive heat warning, depending on how some morning clouds affect the way temperatures start off. There is a very slim chance, around 20 percent, of a some pop up storms Thursday afternoon. Any that do develop will have the potential to be very strong with torrential rain, lots of lighting and damaging winds.

The heat will abate some Thursday night, but it will still be very muggy and steamy into the overnight hours as lows barely drop below 80 degrees. Winds will be light out of the west for the most part.

Friday looks to be almost as hot, in the upper 90's and a good chance of heat advisories. There is a better chance of storms Friday however any that develop may be severe.
