I'm looking at the hi-res NAM and its way colder at 850mb than the 12km NAM at 18z. Is that usually what happens when you scale down all the way to 4km from 12km. I mean its also much colder than the 12z euro too. Wonder why?

The clown maps reflect that very well, meso details being important here and you see that on the hi Res Euro and RGEM as well.

I think earlier hi res was warmer for 12z? Some of this may be related to precip intensity right at that time snap shot. Previous hours may have had any warmer area further SW.

Warning map is fine..although I would put Essex county in pink.

 

Technically the interior of Essex county IS pink. I think I recall the eastern half/the shore going above 0 C on the last couple Euro runs at the height of things, so this could line up well with that.

 

Or is your thinking more that they do well on the back end, enough so to meet warning crit?

They have some latitude too..my guess is the area north of Cape Ann will do pretty well. I mean maybe right at the beaches is a bit less.

No, it's the model. I mean what a joke.

It's generally garbage no matter what they do to it. I shake my head when forecasters take a lot of time racking their brains and giving themselves anxiety trying to understand and incorporate the gfs into a forecast - especially when the chips are down. How bout this - use other tools and step away. It's ok to not consider it. If i'm wrong then I'm wrong but I'll go down with the ecmwf/ecmwf ens any day over this other junk.

Ive said that for years and taken crap from mets .,you just simply don't look at it or use it. Period. My preaching is being heard. You are now an official member of my church

This will be the first good test for both proximity in the 2-3 day range (which it failed) and thermal profile in the near term. It's already a warm outlier.

This is the worst part about it. It can't nail a winter storm in the northeast...it just doesn't. Occasionally it scores a coup, but that is a pretty rare exception. So often it actually just totally chokes in a sizable event.

The last few winters it exhibited an alarming trend on several events, i.e., the solution getting less accurate and having less continuity within 72 hours with each successive run. That's not exactly something that infuses confidence. When a model has shown that it's 96 hour forecast is better then it's 24 hour forecast, that's a bit of an issue.

It seems that it's particularly bad with east coast cyclogenesis. When it's solutions are flopping around wildly run to tun it makes the model completely unusable IMO.
