As WAR expands, do our snow chances increase? First wave may produce a middling event-solid advisory and possible low end warning for MLK Weekend

Not that anyone asked me but I would sans other guidance in lieu of a 50/50 blend of the 12z operational GFS and Euro and call it a day.

Discounting all predecessor runs, too, as they were deltas on their way to what became a pretty starkly clearly converged solution.   

Not sure why a glance at RGEM ever drives one to sullen regret over previous interpretations and so forth.  Do yourselves a favor

I actually think that’s a pretty good call. I could see us on the coastal plain losing a decent amount of qpf at the beginning. 
 

Any relation of this storm to Christmas 17’? That was the last time I remember a changeover to a few inches from a strengthening departing storm

This is probably a well handled 6"er, won by the efforts of the American guidance types ... (sans the NAM and the "yellow" flag).  Now with the late/recent arriving endorsement run by the top dawg model, which other than irrelevant minutia, was similar to the 12z GFS, this should be an easy call at this point.  If it all did something else, that's a failure on the modeling and be done with it.

There could be some lollypop 8" totals but I still have issues seeing this as a bigger QPF verifier due to constrains of

A, storm translation speed;

B, compression circulation mode capping aspects related to development potential.  

These limitations have been in place for days on this and that's not really changed.

Will could answer that I think . He’s Encyclopedia Willanica with snowstorms

Anyone know what model Albany is seeing that would suggest anything like this?? It looks ridiculous

For reference, all offices produce these maps the same way.

WPC has a super ensemble and they ship us all the members snowfall distributed into bins. You end up with some version of a curve, and we picked the 90/10th percentiles off that curve essentially. So this is probably a result of some wild Kuchera members.

I don’t think Boston is going to lose that much QPF at the beginning. Maybe a little bit as they wait for the BL to cool…Xmas 2017 needed a deeper dynamic cooling from higher aloft before flipping to snow.

You'll find that Albany, for lack of a better word...sucks. Also they will cherry pick totals to come closer to forecast verification. I flipped out about it a decade or so ago and they banned me from their FB page lmao.

would love to petition to have southern vermont given to Burlington
