I can remember a few times it was the ONLY model showing something and that happened. The problem is it's so inconsistent and unreliable and goes off on tangents with feedback issues and problems with chasing exponential errors...that you have no idea when its on to something or just being the NAM. On the whole it probably just adds more confusion and stress even if once in a while its right. Expand At one time it seemed like the NAM was especially good at sniffing out warm noses at the midlevels that would so often crush dreams for us SE weenies. Not sure if that is still true or not. 3 Link to comment Share on other sites More sharing options...

I can’t imagine it goes down like that but man will it be crazy if it does. Gradient will likely be a bit more smoothed out than that but still, this could be one of the crazier gradients we’ve seen Expand Not sure I've ever seen a gradient quite that Sharp. Frederick is basically nothing. Head down 270 about 15 mile and your pushing double digits. Just crazy 3 Link to comment Share on other sites More sharing options...

Expand But looking at just the BWI plume, for example, there are a few that are basically no snow, a couple with decent snow, and then pretty much 80 percent of them are below the mean, which is about a foot. So I'm not sure it's really being that skewed by the crazy high members when almost all members are pretty crazy high. Link to comment Share on other sites More sharing options...

DDweatherman Posted January 3, 2022 Share Posted January 3, 2022 @psuhoffman realizing I replied all to the zoom from earlier. Agreed on that northern cutoff, the temps are just way warmer than we’d expect for this type of gradient. Link to comment Share on other sites More sharing options...
