Let me speak to the Asheville snowhole. Every year it is talked about, but Asheville and Buncombe County still average more snow than roughly 93 of the 100 counties in North Carolina. It is talked about like it is Southern Pines or something. Most North Carolina people except you high elevation guys would take Asheville snowfall.
It does exist. That can't be denied. This high mountain ranges are powerful. But sometimes the models exaggerate the effect.
Why do I care?? I don't know, lol. We are on this site talking about snow. We are all a little weird,lol. At the end of the day, it is not important, but yet here I am.
