March was weird. Penacook saw four sub-zero days. Three were the coldest lows of the winter and the fourth occurred without radiational cooling. That day Pepperell MA had a daytime high of only 12.5 (it was 15 at 0000), the coldest March 6th in 25 years of record keeping. March was also the snowiest month of the season, and combined with three snowfalls in April most stations wound up with total snowfalls and SDDs closer to average than anyone expected at the start of March. Many stations had more snow in April alone than the total up to the end of January! Penacook had totals very similar to 2005/2006, some other stations had significantly more, some had significantly less.

I think depth days is a great statistic, and I'm surprised that it is catching on slowly outside of the NE Weather Spotters mail list. I never expected that the NWS would embrace it quickly, but I had hoped that TV meteorologists would start using it, in monthly summaries, if nothing else. It would be nice if ski areas would use it, but they may not wish to if they are not likely to be #1 consistantly. (And if only one area reports depth days, it would not be a good comparative statistic.) The University of Vermont has graphs of snow depths at Stowe through many seasons.
