The 90s stick around for the rest of the week with quite a bit of sunshine as high pressure at the surface and aloft builds into the area. Downslope winds will mix dewpoints out into the 60s each day, so it won’t be as humid as it could be in late June. The heat index on Wednesday, in fact, should only top out a degree or two warmer than the high. Air temperatures will top out again in the mid-90s on Thursday, but a little more humidity will make it feel closer to 97-98°. By Friday, winds will go more southerly and dewpoints will stay more steady in the low 70s, which should yield heat indices around 100°. Heat will continue to accelerate heading into the weekend, with the first Heat Advisories of the season possible as we bring in July. Hydrate regularly and be sure to use sunscreen if you’re spending time outside, especially during the peak of the afternoon.

Tropical update: Mostly quiet, though Cindy’s remnants still have a chance at regenerating

The remnants of Cindy are still being monitored for an outside shot at possibly regenerating into a tropical cyclone as it heads north toward Nova Scotia this week, but chances there are pretty low overall, and regardless of what happens with it, it’s of no threat to the Lowcountry.

Elsewhere, the tropics are pretty quiet. (Definitely not complaining.)
