Heat advisory today from noon to 7PM. Be ready for heat indices 110-115° this afternoon especially along and east of Highway 17, where the highest dewpoints are forecast to pool up.

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.

We look to get a break from the rain on Wednesday as some slightly drier air works into the area for a spell. It’ll still be plenty hot, though — lows start in the mid-70s away from the warmer coastline to head to the mid-90s in the afternoon as persistent westerly winds delay the seabreeze once again. Expect heat indices in the upper 90s to around 100° with dewpoints suppressed to the upper 60s.

From there, moisture returns to the area and our thunderstorm chances respond in kind as disturbances swing through the trough aloft. There’s a small chance we could deal with a thunderstorm complex in the morning before more thunderstorms fire later Thursday toward peak heating. So it shall be on Friday as well, with a slightly better chance of storms in the afternoon given slightly richer surface dewpoints. A few storms could be on the strong to severe side with damaging wind gusts the main concern. Temperature-wise, expect highs to top out in the mid-90s each day after starting out in the upper 70s. Heat indices will head north of 105° again and could creep toward 110°, so be ready to take heat safety precautions during the afternoons before thunderstorms get going.

After a day in which heat indices spiked to 117° at Mt. Pleasant, we should see another round of hot weather on Tuesday, though perhaps not to the extremes we saw on Monday with somewhat lower dewpoints behind a stalling front. Still, heat indices could approach 110° especially near the coast, and another Heat Advisory might be coming down the pike as a result.

Another thunderstorm complex will move across the South on Tuesday, and could bring some impacts to our nook of the Lowcountry in the evening hours. A lot will depend on how far south the front ultimately gets. For now, the best risk of severe weather looks displaced to the south of the Charleston metro, but we’ll want to keep an eye on this as the day goes on in case things change.
