It is currently snowing here in New Hampshire (not uncommon). What is slighty uncommon is the size of the snow. It seems like multiple flakes are combining and creating little chunks and larger chunks. (4cm- 16cm). What causes this? I've seen it before and am very curious about why this is so. Just interesting. Thanks!

Hi Allen

Snow flakes are created several thousand feet above ground in temperatures below freezing, sometimes, along the way to the ground they will pass through a slice of the atmosphere that is above freezing which will cause them to stick together as they then fall into a lower segment of air that is below freezing as they continue to the ground. This is what happened to your snow:

Another possibility is Graupel / Pellets :
