We’re back to heat and humidity for Thursday as the brief respite of drier air comes to a close. Lows will be rather balmy — upper 70s away from the coast, likely at 80° or above closer to the coast and in Downtown Charleston — as the high temperature heads to the mid-to-upper 90s in the afternoon. Expect heat indices 105-110°, with the warmer heat indices near the coast where the higher dewpoints will be found. NWS notes a heat advisory might be needed; will keep an eye on that.

A few thunderstorms will be possible during the day Thursday as a disturbance moves by to the north. A couple storms could be on the strong side with damaging wind gusts the main concern. Not everyone will see storms, though.

Friday & the weekend: Heat continues, with periods of storms

We will stay pretty hot heading into Friday and the weekend. Expect highs each day in the mid-to-upper 90s with lows in the upper 70s to around 80° being fairly common. Heat advisories are certainly possible with heat indices running between 105-110° — and perhaps beyond — each afternoon.

Expect much more in the way of showers and thunderstorms to develop across the area Friday. Once again, a few of those storms could be on the strong side with damaging wind gusts and frequent lightning. Heavy rain will also be a concern as well in some spots. More typical afternoon and evening thunderstorm chances return to the forecast for Saturday and Sunday to bring some relief from the heat.
