Weather Forecast and High Temperature Map for North Carolina and South Carolina

Slight Cooldown Wednesday, Welcome by All

Okay, so cooldown is probably the wrong word, but I certainly got your attention didn’t I! The cooldown Wednesday will have everything to do with dew points. Air temperatures will be very similar to Tuesday, with the Piedmont regions of NC/SC reaching highs around 90°F. These areas tend to feel the most muggy (as compared to the coast or the mountains) as moisture, transported from the coast via easterly winds, becomes trapped against the mountains.

But good news for Central North & South Carolina! While the day will start VERY muggy, the dew points should drop throughout the balance of the day. This means our relative humidities will also decrease. Around 10am, most locations will have a humidity in the 70% to 80% range. By 3pm, even though temps have increased, dew points will drop giving humidity values in the 45% to 55% range!

Pesky Late-Day Storms Continue for Some, Despite Cooldown Wednesday

If you live in North-Central North Carolina, around Raleigh/Durham and Greensboro, then you should have nearly cloudless skies to go along with the cooldown Wednesday! This is also a sign of the drier air moving into the region for Wednesday, leading to lower relative humidity. Charlotte will also be mostly sunny and should have less than or equal to 30% chance for rain/thunderstorm development (and I think that is a little overblown, personally).

Columbia, SC should also be reasonably dry with regards to precip for the day, but we can not rule out a stray storm here or there. The best chances for precip look to be along the southern coast, from Charleston to Myrtle Beach, with lesser chances along the Crystal Coast and Outer Banks regions. We could also see some more persistent rain activity along the mountains, especially the extreme western counties of North Carolina.

It is worth mentioning that river flooding is still a problem for the Tar River in Eastern North Carolina. You can always check the National Weather Service for the latest warnings, or check out the latest tweets and other information about alerts and hazards on our site, for North Carolina or South Carolina.

All in all though, it should be an enjoyable day. Don’t forget, the heat is still coming!

Late day chances for thundershowers along the entire Carolina coast, from Charleston to Elizabeth City. Central South Carolina may have to deal with some storm activity, but chances are low. Central North Carolina in Charlotte, Raleigh/Durham, and Greensboro should have nearly cloudless skies for Wednesday. Good chances for rain in the mountains, including Asheville and Boone.
