Reply to comment by Ayit_Sevi in Final Snow Map & Messaging For Tuesday's Nor'Easter by TheCloudBoy

I was curious as well, and found this link which gives a great explanation.

TL;DR: This is the snow to water ratio. So 5.5:1 means if you took 5.5 inches of snow and melted it, you would get 1 inch of water. "Light and fluffy" snow might be 15:1 or 20:1, whereas very heavy snow would be 10:1 or below.

Yep, that's exactly how I would have explained it! Wet bulb temperature is another important factor when considering how sticky it is to trees, power lines, etc.
