East Coast Snow perspective, part 2

I know it's not a perfect comparison because of the climatology of the respective regions, but I've updated the stats from the post I made yesterday.

See below for more on the numbers I was using.

All these numbers are 1971-2000 normals and snowfall data for Feb. 1-10:

Location                Feb. MTD 2010   Feb. Avg. Snow     Annual Avg. Snow   % of Normal
DC-Reagan Airport       31.9"           5.2"                  15.2"             210%
DC-Dulles Airport         47.9"           6.2"                  21.2"             226%
Baltimore                    49.2"           6.4"                  18.2"             270%
Philadelphia                44.4"           6.6"                  19.3"              230%
Average                    43.4"            6.1"                 18.5"             234%

The average February snowfall for Grand Rapids is 12.2", and the yearly average is 72.2".  Muskegon's averages are 18.3" for February and 105.5" for the year. 

So, if you calculate based on the totals for those four East Coast sites, it's the equivalent of Grand Rapids getting about 169" of snow (that's more than 14 feet) in ten days, and about 247" (20 feet, seven inches) for Muskegon.  Yikes!!!!
