I've written notes on snow storms back to the big storm in 83. i would document snowfall totals. the only other thing i note besides snow is if we break a record on temp, high/low and any other unusual. lost everything before 2002 i think. other then my 1999 day planner with snow weather notes.
edit- speaking of notes, we were talking about Miller b's the other day. I went back to my notes. 1 notable Miller B Was February 16th-17th 2003. We had 32" between those 2 days then 4" more on the 18th. i think maybe it was Mag that picked out that date in the discussion.
