Friday & the weekend: Break from storms Friday, scattered storms over the weekend
Drier air moves into the area for Friday, yielding mostly sunny skies and a rain-free day. We start the day in the mid-70s before highs head to the mid-90s in the afternoon. Drier air mixing down from aloft will temper dewpoints somewhat, and this will help to keep heat indices from getting too far out of hand. Still, feels-like temperatures will top out in the mid-to-upper 90s. So, while it’s not going to be cool outside, it’s also not going to feel like it’s 110°. (Take the wins where you can get them.)
Scattered storms head back into the forecast starting Saturday afternoon as a front stalls out nearby and waves of low pressure move along it. Surface dewpoints will head back into the mid-70s, and this will yield heat indices over 100° Saturday afternoon before storms fire. Still, coverage should be scattered at most with ridging aloft creating a bit of capping.
Sunday will run a tad cooler (air temperature-wise, anyway) as surface winds turn more onshore. Expect highs in the upper 80s to around 90° in the afternoon, but heat indices will run around 100°. Scattered showers and some thunderstorms will be embedded within this onshore flow, and will be coming ashore from time to time, but by no means is it a washout as coverage should once again generally be in the scattered category. So, while it’s not the perfect setup for the last weekend before school starts, it won’t be the worst you’ve ever seen, either.
