Yeah that's a substantial north jump on the UKMET,,,if GGEM also comes jumps north I'd be the surprised, if Dr.No doesn't say Yes. 

The UKMET flops around all the time, and the GGEM had some weird double-low kind of structure for the last couple of runs. It would be good to have them I guess, but this is the timeframe I'd really want the Euro to start showing a hit for me to really be confident of something.

I think all in all, the models basically ingest given data. Many times this is expressed wrongly. But as you get more models that begin to display the same information, then it becomes consensus. So many variables come into play with so many different setups that it is impossible really to say which models will handle that specific setup correctly. This might be an example of the euro ingesting this specific data set and displaying it wrong. But, as new data comes in it eventually will display it closer to what the outcome will be and eventually the models do in some way converge on a solution

Very well put sir.  Good post.  Absolutely accurate.

Pretty big differences on the 0z GGEM 60 hr panel compared to 12z GGEM 72 Hr....s/w is not as strung out and looks way more amped, with significant height rises along the east coast, 1007 mb low along the southern AL/GA border whereas before it had a weaker surface reflection in the GOM

GEM at 74 hours...

That is one hell of a shift north. Last run it had zero precip north of Cape Hatteras!

Haha I know...wild shift north ! Not sure if many have seen...but the GFS is also closer to bringing back the storm for next Sunday....and literally has an additional 3-4 threats of snow throughout the run and is frigid much of the time !

I have been calling that one for the 22nd into the 23rd on my blog for two days already.  That looks like a definite too as it has shown up consistently on the model every day now since 384 hrs out basically.

I've liked this storm for days now, this probably won't be a bomb but I can see a 4-8" event, maybe slightly higher for some. The 50/50 low structure will prevent this from becoming too amped and too far to the northwest so I don't think that's going to be an issue plus the still progressive nature of the pattern makes that unlikely.

 

It's more likely to stay further south but seeing the trends, I'm liking where we stand. I'm hoping the Euro can confirm that.
