Given my lesser November snow, 2.1" is significant. Out of 128 Novembers at the co-op, there's both Nov. temps and Nov. snow in 124, and the AN/BN split is right down the middle. (It's a bit surprising that they're equal, given the sample size.) So if AN Novembers run 4.7" and the total average is 6.8", the BN Novembers must average 8.9", nearly twice the ANs.
