I just got off the phone with the Randall Osterhuber at the UC Berkeley Central Sierra Snow Laboratory.  He gave me his impressions of the 2012/13 winter thus far and all the numbers on Cumulative Snowfall, Snow Depth, and Precipitation for the 2012/2013 season.  We all know it wasnโ€™t a great year, but itโ€™s good to look at the numbers.  The numbers donโ€™t lie.

note:  The UC Berkeley Central Sierra Snow Laboratory is located at 6,900 feet above sea level on Donner Summit, California.

โ€œJanuary & March are our highest snowfall months and this year both those months were well below average.โ€ โ€“ Randall Osterhuber

QUICK SNOW LAB NUMBERS  as of ARPIL 4th, 2013:

โ€“ 50% of normal Cumulative Snowfall

โ€“ 22% of Normal Snow Depth

โ€“ 85% of Normal Precipitation

Why so high for precipitation?  Because we got a lot of rain, not snow, at the Snow Lab.

When I asked Randall to tell me how this season was unique, he had some interesting remarks:

โ€œOne of the main factors this year is the huge discrepancy in snow depth per elevation.  Here at 6,900 there isnโ€™t much snow, but up above 7,500 feet thereโ€™s still quite a bit of snow on the ground.โ€ โ€“ Randall Osterhuber

โ€œThose big, early season storms in December left mostly rain here at the snow lab.โ€ โ€“ Randall Osterhuber

โ€œMost of the snow on the ground here today fell pre-Christmas.โ€ โ€“ Randall Osterhuber

โ€œJanuary & March are our highest snowfall months and this year both those months were well below average.โ€ โ€“ Randall Osterhuber
