Like you said, its bias for overamping storms is obvious with this one. Pretty much every other model is progressive with the storm and only gets lighter precip into WNC either way,
Yes I believe so. Originally it had my 30 year average at 3.3 which was not even close. I called them out on it and they admitted they were missing snowfall data for a couple years and remade it.
I remember when they made this graphic they took a lot of flack. This is an edited version of the original. The original omitted a couple seasons of data including big winters of 1988 and another so the totals are lower than expected for some still. My 30 year average in Marion is around 10 inches not 6.6.
