These are ensembles. They don't show "positive growth snow". That ens mean is smoothed and is quite impressive tbh. Some monster hits among the individual members. Euro weeklies, CFS, and GFSx all have the same pattern progression and idea as we near the Ides. Couldn't care less if it melts in a day or hours. That is a realistic expectation given the calendar. I would enjoy every flake as it falls.
