Well with the NAM's latest run, it shows KY gets thumped with backside snows. It starts out as a heavy rain with flooding potential, then turns into a good 3-5 inch snowfall. The GFS however does not show as much backside snow resulting in the totals I just gave.

The consistency the GFS has shown the past 2 to 3 days, I have no other choice but to believe the GFS has caught onto something, and every other model is going to follow suit. But in answer to your question, I believe the big snows of the 90's showed similar results with inconsistent model runs that ended up hammering us. I'd pretty much expect the opposite here though.
