I want to give a couple disclaimers quickly. I have not focused as much on central NC and have lower confidence in that area. It wouldn't shock me if the northern Foothills found a way to sleet longer and didn't make it to 0.3", but they just as easily can exceed that. I have not focused as much on GA or Raleigh or eastern NC/SC and do not want to provide a forecast that may be ill-informed. That said, here is my take on the ZR potential today into tomorrow for primarily western NC and SC:

I would consider this an abnormally low confidence forecast. There will be more valley/peak variance in NC than this map indicates but I didn't get into the weeds on that. Generally expect lower accretion in interior WNC valleys, especially further south.
It would not surprise me if the Upstate got more like a general half inch, but the upper range of my forecast is absolutely doable.
As for sleet, low confidence, but generally expecting an inch or so along I-85, 1-2" north
TO I-40, and 2-3" north
OF I-40. Let's hope that low level cold wins out and "all" we manage is 0.3-0.5".
