Rest of the work week: 90s return

Jared Smith / May 19, 2026 at 9:01 PM

High pressure at the surface and aloft along with plenty of sunshine will help bring the 90s back to the Lowcountry over the next few days for the first time since mid-April. Dewpoints will not quite head back to those summertime 70s just yet, thankfully, so heat indices will remain in check, but it’ll still be plenty warm and a harbinger of things to come as we head toward June.
