Granted. Sometimes the warmnoses do come in a little warmer.
But this is not a amped system with a powerful H850 lp running through the coastal plain of GA, SC, NC, VA. With a bombing sfc low off the coast.
This warm nose exists roughly 800mb to 750mb. From a over running system transitioning to a coastal with high potential of alot of frontogenesis.
Not exactly sure where in Charlotte you stay. But judging by the soundings and raw data. Around Charlotte and north ward with plenty of moisture and lift a warmnose should be overcame.
Granted you may have some pingers mix in briefly. The warmnose is not that strong.
Even around Raleigh and south those levels stay at or below freezing.
