Thursday will be the coldest day of the week as a little reinforcing cool air moves into the area from the north. We start the day in the mid-20s, but the wind will factor in a bit more than the previous couple mornings, driving wind chills down into the teens across even the Charleston metro area. Thus, a Cold Weather Advisory will be in effect until 9am. Despite unfettered sunshine, highs will struggle to the mid-40s in the afternoon, and with the persistent north to northwest winds around 5-10 MPH, it’ll still feel like the upper 30s throughout the day. Layer up accordingly – you’ll be glad you did.
