FIRST ALERT: Summer heat index heads above 100 the next few days

Rain chances will be at a minimum until the end of the week

Sean's Sunday Evening Update

MYRTLE BEACH, SC (WMBF) - The heat will be on repeat going forward through midweek, especially as increasing humidity adds insult to injury with triple digit heat index.

Tonight, most areas will remain dry. A few isolated evening storms are possible before sunset, but the activity will not be as widespread as Saturday. Overnight, expect dry skies and muggy air as you wake up Monday morning with temperatures in the middle 70s. Sunrise is around 6:16AM for those looking to walk the beach.

Monday afternoon features hot temperatures, upper 80s along the coast to middle 90s inland. It’s the heat index, the combo of heat and humidity that we have to watch between 1PM and 6PM as that when it will likely feel above 100. If you have to be outside during this time, stay hydrated and take breaks to stay cool.

Tuesday and Wednesday will be similar as far as heat goes. We could see the heat index get as high as 105, which would meet criteria for a heat advisory. After Wednesday, we return to our summer afternoon storm chances. Thursday, Friday and the weekend feature rain chances at about 30% in the afternoon. For those not lucky enough to see an isolated shower, the heat index likely will climb between 100 and 105.
