10/4/2012	10/07/2012 5:00 PM	4	0.24	0.0	M	Based on nearby measurements, about three-quarters of an inch of snow fell in the early morning hours of 10/5
1/12/2013	1/14/2013 7:00 AM	3	0.01	0.5	M	estimates 0.3" snowfall during this period. Depth includes some old snow scattered about the yard
4/8/2013	4/10/2013 7:00 AM	3	0.67	7.5	0.78	I did take detailed measurements using snow board, but did not take a reading at 7am-ish on 4/9. Max. snow depth 8.0 through entire storm. Melting occurred from below during entire storm, thus accumulation is estimated. 0.02" rain fell at the beginning of the storm. Total snowfall estimated 9.9". The 0.67" shown is for the gauge total only.
4/30/2013	5/02/2013 7:00 AM	3	0.84	5.5	M	Max snow depth during storm: estimated 6.0"
