It's not like NC always gets more snow than GA/AL/TN/MS in every winter storm. East of RDU is usually screwed except in southern sliders and Miller A type winter storms when it is very cold. March 1993, January 2011 and December 2017 are prime examples of this - great for the western part of the south, but forgettable cold rain/mixed precip events here. Even this last December, Johnston County eastward wasn't so lucky.Poor NC? haha your silly.
And then you have events like January 2016 and 2017 where the western parts of the state hit the jackpot but the eastern gets mixed precip or rain.
