The warm spell peaks on Friday before a cold front affects the area over the weekend. The first 80° day of 2026 is not out of the question on Friday, though a scattering of showers will potentially put a damper on that possibility, especially heading into the afternoon. Like the past couple days, another breezy day looks to be on tap as well, with winds gusting 25-30 MPH at times as the heating of the day helps tap into somewhat stronger winds aloft. As for showers, they aren’t out of the question really at any point in the day, though coverage should increase a bit getting later into the afternoon as the cold front stalls out across the Upstate and Midlands. Not expecting too much in the way of rainfall amounts on Friday, though some brief downpours aren’t out of the question, especially inland from the coast where a little more instability may exist.

We’ll see more in the way of cloud cover and maybe even a few showers on Thursday, but that won’t stop temperatures from getting back to the mid-70s after a warm-for-February start in the mid-50s. Deep southwesterly flow will continue to pump warm and moist air into the area, and as temperatures warm into the 70s, this could spawn a few popup showers (not something we often say in February!) along with gusts around 20-25 MPH.

After a fairly warm day (away from the coast, anyway, where temperatures ran some 10°+ cooler), we’ll turn even warmer on Wednesday as high pressure slips offshore, pumping in warmer air from the south and southwest. Wednesday starts around 50° with perhaps a few patches of fog, and we’ll warm well into the low-to-mid-70s under a mix of sun and clouds. Winds will be a bit breezy out of the southwest, generally around 10-15 MPH during the afternoon as mixing from daytime heating taps into 25-30 MPH winds a few thousand feet off the deck.

A warming trend kicks off Tuesday as high pressure moves overhead and eventually offshore. It’ll be quite a nice day after we start around 40° in the morning; temperatures will head well into the 60s by afternoon with plenty of sunshine to be had and comfortable relative humidity values. Winds won’t be quite as strong as they were on Monday, either, with speeds generally around 5 MPH. Winds will shift around to the southeast as high pressure slips into the Atlantic, a harbinger of warmer air to come.

After some much-needed rain on Sunday, sunshine and warmth return for the new work week as high pressure remains the main weather driver for a few days before shower chances return to the picture later in the week.
