According to information at the National Climatic Data Center, here are the record 1-day, 2-day, and 3-day snowfall totals by county. These are based on data through December 2006. At most locations, snowfall is only measured once a day and many snow storms can last more than one day. Therefore, the 2- and 3-day snowfalls may be more accurate in identifying the big snow events.
