Today the GFS caved to the EURO.  And we are supposed to take its new solution when everyone is saying the GFS just made a thermal adjustment of some kind????  I think this could go either way five days out as it always can, but there is no reason to give the GFS more credence when it is playing catch-up.  And when is the Canadian ever correct?

Not sure what you are on about here. I focus on the synoptics and the features at the surface and aloft each model cycle, so I guess I see things from a different perspective than you do.

It's maps like these that suck the air out of the room.

It's the very beginning of our snow climo and that always requires at least a modest BN temp profile where it counts. Especially when slp is fighting to bring it down into the mix. In mid Jan, marginal or AN mid level temps to our north work fine because it's pretty cold anyways. I'd love to see snow as much as anyone but temps are not an ingredient we skip over too easily

can you pick up a package for me? Go to the Nana plaza. Ask for Matilda!  thanks

Many much more classy places to go than Nana.  At times it is off-limits to farong (foreigners) and can be a violent place when folks misbehave.  Lived not far from it for nearly 3 years.

83-84 was a stinker here but 83 featured a nasty arctic outbreak leading into the holidays. Mid-Dec 83 500mb analogs have been popping up regularly last 4-5 days. It did snow a few inches that Dec pre-holiday. From afar, it doesn't look like a huge artic outbreak is ripe but certainly possible. Something to watch. If the epo ridge starts freezing western Canada, it's only a matter of time b4 a lot of cold pushes pretty far south and east.

Honestly, I can't believe I'm saying this, but this is one of the nicer setups here in a sense. A lot of our threats are usually thread-the-needle/one phase can mess up the whole storm kind of storm, but this one is just us relying on one trough and its track. Cold is there associated w/ the trough, just need a good track. The better track (06z GFS yesterday/00z Euro) would definitely fare well here.

WB 12Z EPS at the end of its run….cold Christmas morn.

Everything considered, including comments from several media outlets regarding frigid conditions in the East near Christmas, its not really that cold. We had colder  already, teens as low temps were recorded at many locations.  That was when we had the record - EPO a while back.

No matter how many times you say it the usual suspects will still melt down and unleash a rant in tongues when it fails. 
 

 

As you know, the rule of thumb is once the surface low is north of our latitude, the precipitation shuts off in these situations. What could keep it going is lift generated by the 500mb low, which euro does seem to show.

It's a shame there is literally zero deep cold anywhere to help. Mid level temp maps look terrible. Lol. You know there's something really wrong when a blocked surface low totally ignores the baroclinic zone off the coast because it's impotent. So what's left is a complicated  mess both at the surface and upper levels. Our "complicated" batting avg needs a pinch hitter or something 

So in a word...this came about a couples weeks too early? Lol

Yeah i can’t get hyped about snow chances with this storm as of yet. Can’t ignore the obvious with Tangier to Kent Island type track. Climo and just too much warm air flooding in. 
 

Big ass block can only do so much and if there isn’t help with a decent cold air source then mids win

I would be worried about marginal cold air prior to the system and pretty toasty Atlantic Waters and the winds in off the ocean.  I do not see how this system is a purely wintery affair the only way is if the whole set up is further east.

We have a pretty strong high to our north with CAD which is usually undermodeled so the cold air at the surface does come from a decent source. But yeah, I don't think we get a purely snow event, but a wintry mix -> snow and maybe some rain is definitely plausible.

Looks pretty mundane. gfs run at 384 very wet out west

^thats impressive cold….not so much for us But you gotta like our chances

It looks dare i say ideal? We dont want the core of anomalous cold centered over us. Those maps in tandem are ideal...there, I said it.

Agree with Wiggum. Unless you just have a bet the Bay freezes over you don’t actually want the core of that kind of cold centered on top of us.  Storms are going to ride the boundary. You want to be on the cold side but not too far. That’s an ideal look Imo.

Between Ji and his new understudy you’d think we were on the verge of 60s through the end of the year.

Ji hasn’t been that bad Imo, just a frustrated post now and then when a specific storm doesn’t work out. The other guy though…is just straight trolling and contributes absolutely nothing of substance ever.
