Winter '11 / '12 - Meteorological Winter - Month Three

CAR alone enjoyed a 'normal' snowfall this winter.  No other station came even close to normal.

March is the last month for the 'season-total' snowfall forecast contest.  Latest round of long range progs hold little hope for a late rally.



Climo columns are the summed monthly totals for DEC...JAN...and FEB.
