The NAM has its flaws, but I think it's ironic to see it written off by so many mets. The two minor events that have occurred so far in W NC, NW SC and parts of Georgia were nailed by the NAM, days in advance. It's had solid footing this year.
Also, as someone living in western NC, I have a hard time buying dry solutions - everything has overachieved in qpf this winter.
