I mentioned yesterday that snow growth may not be great. The DGZ is rather small and higher up in the atmosphere. Most of the forcing is from the 850-700 area with some of the heaviest echoes producing better flakes as that lift reaches deeper into the atmosphere. So basically you have the lower vis, small flake type stuff.
This aftn will be better snow growth, but probably a lot of that 3/4 to 1SM type snow where even though the vis isn’t that low, it still adds up.
