It is location dependent too, even around here. The past 7 years, in the central nj area 15 miles west of Rutgers University, I am:
a tick below ave
Well below
Way above
66% of av
way below
Ave
66% of ave.
Those 7 years are a hair over 23" average for me and I average 29". So yes, it has been below average. But next year if we happen to get a nice winter, I can be right near average again for the past 8 years. His 7 year thing is so cherry picked it is laughable. The prior 7 year to that I averaged 11" above average. If I combine the 14 years, I am above average overall. Somehow the last 7 years are the new norm, but the 7 years prior to that just get tossed.
