Which model is to trust? For this winter, the GFS has done great all though it has not shinned as much lately…and has had no consitency. The NAM has not done well, but has had a bit better with the last few storms as I remember. Which should I trust? The GFS has a clouds and a cold front on Saturday and the NAM has a foot of snow, when on Monday the GFS said 6-8″ if it was cold enough at all levels and the NAM said it was just to warm, and now they've flipped!
