What snow are the Carolinas getting? I admit I don't pay that much attention to weather there, but I just looked at the June data for Raleigh, Piedmont, Fayetteville, Charlotte and Charleston and for the most part it looks like it has been quite warm there. There were a few days with lows in the 50s, but the daytime highs still reached the 80s.
There was a news story about a solitary patch of snow that was left at a ski resort, but big deal. We have glaciers in California that aren't far from the hottest place on Earth, Death Valley.
Even if there was an unusual local weather event, unless you do an attribution study then that's pretty much all it is, a unusual local weather event.
