Picture nearly melted snowflakes, on the verge of melting - so that they are almost translucent. Now, clump them together, somewhere in the atmosphere. Sometimes, the clumps will have a diameter of as many as six centimeters, but that's pretty rare. Usually, they are only two to four centimeters.
Those fall out of the sky. Usually, I will see that just a couple of times per season. Some years, I don't see it at all. It really depends and it only happens when the conditions are just right.
My elevation is about 925 meters. I'm a bit above the 45°, the meridian. I usually get about 3.75 meters of snow, per season,
(I converted it to metric for you.)
I've never seen snow quite like it elsewhere. I'm sure it exists elsewhere, but I've never seen it.

... Just for (very) wet snow.
I'm not really sure what to call it?
