Sey-Mour Snow

Apparently you didn’t look at this then .

 

The weeklies are do or die now? Cheer up buttercup it shows a Building -NAO for mid and late January with a transient -PNA week 3 which has been the thought for quite some time for many, then pretty weeniesh Weeks 4-5 with -epo and -nao

We had a step back today in the good look going forward . Nothing terrible but things started trending back the other way

Just bc nobody posted about it doesn’t mean it’s a step back, geps is cold as hell and gefs improved some and has a great -nao, eps remained steady

Fairly active gfs so far. 

Also first time seeing true Arctic cold modeled in Canada and the Northern US

New Year’s miracle? Bump it NW and get some high pressure in SE Canada and that would work. So much energy flying around who knows what will happen.

EPS was pretty darned cold for us. Def colder than OP GFS. 
 

Regardless, whenever you see cold anomalies just to our south in that NYC-DCA corridor, that usually means we’re plenty cold enough to snow even if we are near avg or slightly above like on that 06z GFS run. Sitting in that -5 to -8C range of 850 temps. 
 

Hopefully we can actually get one of the shortwaves to pop a nice system for us. The really active look is something I like a lot…it will make model watching relevant since any one of them could show up as a storm all of the sudden when we get closer. 

Ya I’m not saying it’s not cold enough to snow, you’d just think it’s colder at first glance. It’s actually just a seasonable pattern until that real cold push towards the end of weenie range.

IMO you are a little loose with your terminology. People get so used to certain phrases that they start taking them for granted. Terms like "nail" and "lock into place" are subjective. The parameters and spatial scale in question as well as your criteria for assessing model accuracy are not clear. Even the term "pattern" is only vaguely defined. It's easy to rationalize having a good handle on something if details and definitions are kept fuzzy.

The magnitude and orientation of 500mb height values at the continental scale are modestly predictable out to about 10 days. But the point I've been trying to make is that regional weather forecasting at and beyond this time frame requires model accuracy that exceeds the current average error. Even if longwave trofs and ridges are roughly predictable, local sensible weather is highly dependent on fine-scale features and evolution that is outside the scope of model skill and only modestly correlated to large-scale features. It's hard enough to see a regional cold snap coming 10 days out. To detect a snowstorm at that range is really hard. And while everybody is looking far into the future for the perfect pattern, a decaying lake effect streamer could drop an inch or two almost without warning.

It's all semantics at this point, it seems like you agree with what we are saying, but are arguing otherwise.  Long story short, long wave patterns are generally forecastable 8-12 days in advance by ensembles.  Whether or not it produces the exact result we want or suspect is a different story..

Tonight would be light freezing rain if anything even falls. Too warm aloft for flakes 

A light warm drizzle down here very festive

6z gfs is really cold . Euro just got colder.

It’s actually not cold at all for the New England forum.  Cold anomalies are south. Actually still a bit above normal until the last few weenie days of the run. Weird bc it looks cold at first glance.

Let's get it solidly inside 7 days before we celebrate. LR ensembles hedge towards climo at the extended ranges. And we've seen hints of this kind of change already this year that did not materialize.

It's actually pretty easy to predict a general 500mb pattern 8-12 days in advance most of the time.. The 12-15 is a bit more suspect but we do nail that well in advance sometimes.. The pattern that will lock into place mid next week for 7+ days was well forecast by ensembles starting at day 13-15 last week... Just because it doesn't snow doesn't mean that the forecasted 500mb pattern was wrong, sometimes we just get unlucky.  In fact many torches are sniffed out well in advance usually by ensembles..

19° off of a low of 15° here, but that comes with some wind unlike the rad in SNE. Chilly for 2020s Dewcember standards!

Don't take away our fake cold "it's the only winter we've got"

12/14 and 12/7 BDR was 25 or below. .. BDR dropped below 30 degrees 8 times since November 1.. 

Found a few stations on the water in Branford and they dropped below 30 the past 2 days as well as well below 30 on 12/14 and 12/7 and 6 times in November .. First one being November 2nd..

Funny, it wasn’t a hit at D10…just a close call…so nothing needs to happen for it to miss. 

Control run is even closer to a bomb on New Years ..Then the Gorilla (Rain this run) on Jan 4th.. Regardless some colder threats showing up for the first time this season..

The GFS looks cold enough to me in the long range

One interesting thing I noticed is that the notoriously cold biased GFS is 0 to +1 for a 7 day anomaly at the surface for SNE day 10-16.. However at 850mb its like -5 to -10..

Not seeing cold air on the long range guidance. Even in the very long range the BN anomalies are confined to the south. NNE is AN. 

Are we in search for cold and dry or snow?

Well I guess maybe fantasy storms put weenies in their footie pajamas....until those get taken from them?? I didn't see much wrong on the GFS. Next week probably sucks and has looked that way for awhile.

Pattern looks good, who cares about a jackpot at hour 384.. We wait on the Gorilla and hope for the best..

Will it start snowing hr 12?

EDIT GDPS has you pretty icy by hour 170 .. maybe some freezing drizzle for SNE Christmas eve morning

Funny how we feel so defeated with the likelihood of another snowless December for many, yet I just realized it is still Fall for 11 more hours..

FWIW the 6Z GFS looks quite different than the last few runs...

Verbatim no snow but that’s a loaded pattern and cold for a change

Just took a closer look wow pretty weeniesh . Very cold for January and even more February with a more active pattern in January drier in February 

GEFS look better again, some NAO blocking developing as well. 

Jealous haven’t had anything good since 5am here…

BDL and HFD both well into the 50’s. IJD 61

No meh 

Best was just before I woke up it seems here.. 

Sun poking out a bit, 3.71" Max gust seemed to be 50-55 in this area, about as expected.. No power outages in my town.

Ijd 61. Inland is worst

EDIT that was not updated.. Just rechecked NWS reports many 55-65 in Western CT around 4-5am.. OXC 53mph 66 Stamford Coop.. 56 Meriden Airport
