MYRTLE BEACH, SC (WMBF) - Rinse and repeat, with less rinse and more heat on repeat through the weekend.
This morning, the heat builds in quickly. Heat indices by noon already are above 90 in most areas. By the afternoon, coastal highs will be in the upper 80st and reaching 95 inland. The temperature along with the humidity will have a heat index above 100. Although it will be hot and oppressive, the heat index is just below heat advisory criteria.
Shower chances again remain small, due to the drier air in the upper levels of the atmosphere. An isolated shower can't be completely ruled out, with the small window of opportunity during the middle of the day.
Tomorrow, we keep the heat locked in as highs climb into the 90s and heat index in the triple digits. There are some signs of slight relief by 4th of July on Wednesday. The mugginess will go down just a tad, but an increase in the chance for afternoon storms.
