Wintry Winter 2018-19 Discussion

Very interesting look on the Euro. At 168hrs both Euro and FV3 have a very similar look. However the Euro then dampens the ridge out west and allows a powerful SW to break off the Aleutian low into the west coast. The FV3 does not, and while the model shows nothing, 500mb screams a big time threat.

Should be very interesting to see the result and what may be our first significant threat time frame.
 
I was wondering if it would be better to post on the November thread now instead of this one since everyone seems to be talking about specific model runs and threats now instead of overall thoughts on winter. It seems the pre-game show is over, and it's game time now!
 
‍just a little ...... is feel a lot better if they were switched around. Day 7/8 isn’t that far off . I hardly ever bet against the EPS

I'll bet against the EPS every time. Yes I'm still ill.

That being said it, the 18z GFS has a 561dm ridge north of the Hudson. Crazy.
 
Complete chaos. Gotta get rid of that gigantic low in the Pacific.

Welcome to weather ... :eek:

It'll settle down, and then someone somewhere will be happy and someone else somewhere will be sad ... so enjoy the uncertainty and know in your heart of hearts that the someone sad lives way outside this neck of the world ... :confused:
November 19
 
I’m not so sure many people score the first week of December. Perhaps mid December be better.

Something is missing!?? Oh yeah, that giant +PNA ridge! That escalated quickly! :D
 
So far through Nov 17th the pattern is very similar to the previous Nov snowy/cold nino composites. For Dec the composites show npac low more east then we like but retrogrades west into Jan/Feb. Thus temps get progressively colder. In short, I like where we are. (knock on wood)

December/mid December can't get here soon enough. Can we keep


Do the euro ensembles show us losing the greenland block the first week in December? Looks like from dts post...:confused:
3 to 4 weeks away, so don't fret. DT loves it when anything looking good south of the NC border even appears like it may collapse ... Take it and him with a huge and bitter grain of salt ...
Hell, he even thinks the entirety of the Civil War was fought in PA and VA ...
Off the soapbox before love shines brighter ...

Yeah, whatever gets Richmond/DCA snow, he’s good with! I think he’s bitter that the severely cold part of the Thanksgiving blast, is going to hit BOS/NYC hard, and not him

Not sure, but we can’t have wall to wall cold!? Has to be a relaxation period, then the hammer drops Christmas-Feb!

No and yes.

That screenshot is from the weeklies which does have a neutral NAO by Dec 6...but that’s hour 370-400 or so. I wouldn’t put much weight into that. However, what he’s pointing out is the deep negative anomalies for the EC trough. Usually a sign of a storm. Very impressive negative anomalies for so far out.

Not at all saying this year is like a 09-10, but I believe I remember that year, models kept trying to break the blocking down. And it just kept coming back.

I certainly hope so. I'm sure we can have a decent winter without it, but the blocking is what has me excited.
 
Euro threat #1. Euro caved to the GFS, doesnt tear down the ridge. Now if we can get the southern wave a smidge faster.

There are a few (~3-4) EPS members that produce >1" of snow in central-eastern NC when that s/w comes eastward around day 8-10.

Whatever storm we got in this timeframe would probably be Miller type-A/coastal low in the Carolinas unless more North Pacific blocking appears between now & verification.

Hey Webber I know it's too early to say but does Alabama and Mississippi areas have a chance during this time frame?

No idea on who or if this threat would even materialize I'm just stating generally speaking if one comes to fruition, the planetary-scale pattern we have in place supports coastal lows or perhaps an overrunning event. I've generally noticed it's hard to get big cold air damming events w/o significant North Pacific blocking seeding the continent and northern stream waves w/ frigid Siberian air and getting split flow upstream in the eastern Pacific.
