The afternoon will see temperatures soaring well into the 90s. Along the Grand Strand, afternoon temperatures will reach the lower to middle 90s. Inland areas will see temperatures climbing into the upper 90s with a good chance at a few locations west of I-95 hitting 100.

Increased humidity will send the heat index back into the danger zone on Tuesday with most areas peaking near or above 105 in the afternoon.

A weak cold front will pass through the region by the middle of the week, allowing slightly cooler and drier air to filter into the Carolinas for Wednesday and Thursday. In return, temperatures will fall into the middle-upper 80s. Inland locations will remain in the lower 90s, but will feel more comfortable with the heat index in the middle 90s.

Another round of big heat is looking more likely again for Friday into Saturday as temperatures will likely soar back into the middle 90s. Another round of humidity is likely as well with the heat index returning to 105.

The heat will tend to ease up a bit by the end of the weekend, but increasing humidity will lead to a higher chance of showers and storms at times.
