High pressure will continue to slip a little more to the east today, allowing the resulting return flow to bring a little bit more humid air characterized by dewpoints in the mid-60s into the area. Once again, we look to remain mostly rain-free across the area; the best chance of a shower or two will be in northern sections of Berkeley and Dorchester counties near I-95 closer to a trough of low pressure. Otherwise, expect a mix of high clouds and fair-weather cumulus as temperatures rise into the low-to-mid-90s ahead of the seabreeze. Heat indices will be a couple ticks higher today, generally in the mid-90s in the afternoon, particularly right after the seabreeze and its associated dewpoint surge pass by.
Temperatures and humidity will continue to creep up for the next couple days before a cold front knocks down temperatures — and brings some isolated to scattered storms — for the Memorial Day weekend.
