At least the 12z ED-209 looks better than 6z.

I miss the old days of little access to models, things were more of a surprise when they happened and less of a disappointment when they didn't. I mean, I know I am the same way, I might get 12 inches of snow, but feel empty because the models were showing 18....before I feel like I can't enjoy the fact that it is snowing most of the time because expectations take over. Sure I could just leave the board and stay away from the models 4 times per day, but it is an addiction with no help, lol

There was something special as a kid about waking up in the middle of the night to find the orange glare of the old street lights softened by unexpected heavy snow. Especially if it happened before a school day.

In past years, everybody hung their hats on the hope that an SSW would materialize.. Well this year, we had one. And it did bring the PV and the cold.  but  the rest of the equation seems to be lacking so far.

It wasn't a full reversal.

Looks fine to me...even around MA Pike

How many ways can we find to avoid plowable snow in Boston?

Yeah I posted that earlier. Was waiting to see if someone got my Robocop reference lol. 
 

Euro op was good for the cranberry bogs. At least it didn’t vanish.

Lol, I thought that was a deep terminator reference I wasn’t aware of

It really wouldn’t take much to amp this up a little more…just need that SPV to drop in behind the speeding shortwave a little earlier/deeper.

Even the Euro aloft might argue for more QPF being wrung out a bit further inland...not an uncommon model bias for all guidance in keeping thew QPF too close to the low-level thermal gradient. It's why I think that run was pretty good for SE MA despite most QPF being centered over Cape/Islands. 

But yeah, that could get juicy pretty quickly if you displaced the PV lobe even 75-100 miles west.

Yea, validation of a seasonal is a great post card, and a very appreciated gift.

Look Ahead to latter December & the Holiday Period

 "Given the active, seasonably cold pattern that is expected to ensue and last for at least half of the month, the probability for a White Christmas is above climatological levels, but it remains somewhat dubious for the coastal plane given a possible milder turn prior to the holidays. In fact, the proverbial "Grinch Storm", which occurred in both the 2007 and 2008 analogs, is a distinct possibility".

I wonder how much the op run is influencing this. The last 3 GEFS runs for Xmas eve.

the GEFS is so horribly underdispersive that the OP probably is influencing its ensemble 16 days later

When you have summer heat ridge heights near the winter solstice, I'm guessing it's hard to wash that out even with other ensemble members.

There has been many cases in the last 2-3 winters where both the GEFS/EPS show a pattern at like D12-16 that seemingly not a single Op run over that few days ever shows, if anything its the reverse and then the Op idea verifies more 2 weeks later.  Not sure why that would happen, it shouldn't but I have seen it more than you'd think is normal.
