It’s going to be a rather hot weekend in our part of the Lowcountry as high pressure stacks up both at the surface and aloft. This will keep generally drier air aloft in place, but southerly flow at the surface will help keep dewpoints nice and juicy in the mid-70s. Ridging aloft will keep us limited to an isolated storm or two in the afternoons — perhaps a totally rain-free Sunday, even — and so there just won’t be much relief from the heat. Highs will top out in the mid-90s Saturday and the mid-to-upper 90s on Sunday. Heat indices will head between 105-110° on Saturday and could reach or exceed 110° on Sunday, which puts it into post-July 1 heat advisory territory. We won’t get much of a chance to really recover at night, either, as lows bottom out in the mid-70s on Saturday and the upper 70s on Sunday. We will likely not get below 80° this weekend at the beaches and in downtown, either. Suffice to say, if the outdoors are in your plans this weekend, make sure you’ve got access to plenty of hydration and can take breaks in the shade.
