basically you had the GGEM and JMA caving to the 12z euro...and then the 00z euro comes out and says, why the hell are you caving to me....i cant forecast

Wonder if the better data assimilation and initialization had the euro seeing something in the atmosphere ahead of those crappier models then they saw the same wrong thing 12 hours later. Both got fooled by the same wrong conclusion from the same data only 12 hours apart.

One of the problems we go through with every event that derails expectations every single time is some model or a couple models will almost ALWAYS throw out an outlying max potential run and then that become the new "middle ground". If you toss the 2 biggest and 2 smallest solutions and average the rest of the model suite then it's usually close to reality every time. This only applies to inside of 3 days. Beyond that accuracy drops off too much and too much can change. People down in the dumps because the euro and JMA spit out top end outlying scenarios is just bad practice in this hobby. When 80% of the models show a big hit and then it goes poof....yea, that sucks. But for what we've been dealt with so far this year we've actually done better than expected from the 72 hour mark.

There's 2 things to look for. A "backwards bend" of isobars and cyclonic flow. This feature has both and low pressure off the coast feeding it. It's an extension of the low off the coast providing moisture transport and lift. Precip is typically isolated to a small area. 

This has "overachiever" written all over it.

Heh, euro is hideous. This should be a fun couple hours here. 

You realize over the last 7 runs it's had the 3 snowiest and by a huge factor, 3 meh runs, and the 1 single worst run. I know I keep saying it but it's not an exaggeration the thing is totally useless for making a forecast right now. Lost all cred. But that won't stop people from throwing out the good vibes by improvement on all the other guidance today.

you know when they grade the euro and other models, they dont really grade it based on how it does in washington DC.....but if you are someone using the models to help forecast, you would probably say the models have come along way but there is a really long way to go
