Blistering heat and high humidity will likely reign supreme today, tomorrow, and much of the foreseeable future. The expected reprieve tomorrow has evaporated with the rain. Also, more afternoon thunderstorms are expected (though, likely not as bad as yesterday's).
Temperatures will only be in the mid-90s, but paired with the high humidity will result a heat index around 108 degrees.
The National Weather Service says:
High temperatures in the lower to middle 90s will combine with high relative humidity and result in heat index values of 105 to 108 degrees this afternoon. The highest heat indices are expected to occur roughly along and east of Highway 17. This includes the communities of Beaufort...Hilton Head...Ravenel...Hollywood...West Ashley...Mount Pleasant...Daniel Island and the downtown Charleston area.
A graphical forecast show an even-higher heat index tomorrow, with an evening relative humidity of 94%.
