I may be of a little help...but not much...
I've been to Ski Beech many many years ago with a church group...when we got there...no snow!!!

.
There were several nights when the temp would drop...you could hear the snow guns start up for an hour or two then shut back off due to rising temps. This being said, we had to find other ways to entertain ourselves...I recall the town close by had a nice, intimate mall...and the town also had a pretty college.
There was also a place calls Fred's Mercantile (I think) which was a neat general store heading up to Ski Beech.
It did finally snow before we left...and we did get to ski...but the conditions were less than ideal.
Have also been to Cataloochee and Ober Gatlinburg skiing in east.
We went to Breckenridge, Colorado for our honeymoon years later and skiid, skied, ski'd (you know what I mean).
In comparison:
Skiing out west (Colorado) = Walt Disney World
Skiing in the east (Smokies/NC/Tenn area) = amusement park set up in a parking lot.
The snow in the areas you've mentioned is nothing like the snow out west based on my experiences...snow in the east is very dependent on the weather...the "snow" is often man-made, and can range from snow like stuff to ice, to mush...all dependent on the weather.
Hope this helps...and hope you have a great time!
