I direct your attention to the snowy late 1970s. The following three winters brought these totals for snowfall in inches to Nashville:
1976-1977 21.5"
1977-1978 25.2"
1978-1979 27.5"
This year (2010-2011) isn't even close to those years yet (we'll have to get another 10" of snowfall between now and the end of the winter to even get into the range of the snowfall that fell in Nashville during those years).
I'm waiting on a winter like those to proclaim our snow drought over. Yes, the last two winters have been colder and snowier than most of the last 20 years. However, in reality the total snowfall thus far is really only what I would consder within the average range. I think we need a big dog winter to declare the Nashville snow drought dead. Of course there is still time late this year.
On another interesting note,
three of the top nine snowfalls in Nashville came not just in March but in the
2nd half of March.
