Another comfortable day is ahead with high's to top out in the mid to upper 70's. Shower activity will be limited to the smokies but a stray shower early this afternoon can't be ruled out entirely.
The latest surface map shows the low off the coast of South Carolina slowly working north and providing lots of rainfall for the eastern coast line. The good news is the Smokies act as a "buffer" shielding us from lots of that rainfall at home. As this system works back northward, wrap-around scattered showers will arrive later Wednesday and into the day Thursday.
Taking a look at what I am referring to, showers will stay contained to the Carolinas today and much of tomorrow before widespread activity is likely Thursday. For now, I think this model in particular is "over-hyping" rainfall throughout the region so we are giving it a 40% chance through the day. Depending on how much moisture is still retained across the area and where the low moves will depend on shower chances. Jumping into the weekend, a high pressure system will slide in (later Friday) clearing things up and increasing the overall temperatures. The 90's will more than likely return for the majority of us this weekend as humidity values climb as well.
As I mentioned yesterday, take advantage (especially today) of the sunny skies and comfortable temperatures. We are nearly 5 to 10 degrees below average for this time of the year and that's expected to quickly change in the next few days.
