Liquid equivalent yesterday ranged between 0.05 and 0.15 around the region, with snowfall totals generally yielding ratios in the 20:1 to 25:1 category. To put ratios in a better perspective, the average snowfall yields a ratio of 10" or 11" of snow for 1" of liquid (meaning if one inch of rain fell in the form of snow, you'd yield 10 or 11 inches of snow). Given how dry the atmosphere was, ratios were bound to be enhanced somewhat yesterday but it's usually tough to pull a 20 or 25:1 ratio unless the atmosphere's cold enough aloft and there is just enough moisture present through the lower and mid atmosphere to generate snow. The type of snow many of us saw yesterday was dendritic, which means you can sometimes see the individual flakes such as below.
