No that's cold.

3 things here , One all those higher connected Heights from the PAC thru Alaska and over the Pole

will mean you`re source region is arctic , not Polar . So its low level cold air

 

2 That's at 500 MB , at 2 Meters  where we live the cold air will drain to the bottom of the trough and is cold

 

3 . The Euro drags its heels in the West , so that trough will be further East

 

As it is that SE RIDGE will offer resistance so we can get system that roll W to E  along the baroclinic zone

And in 1994 that was a great pattern .

Thanks for the detailed explanation. So, it looks like we retain the -AO and -EPO according to that map. That's a very encouraging sign. Hopefully, we don't warm up above freezing when the gradient pattern commences.

Next week is cold , and if the trough pulls back next weekend , its back in the east inside 2 days .

As long as keep that height field connected ,you in essence trap the PV and Canada never loses the cold .

0z GFS is insane with snow opportunities and cold. We have a weak clipper Saturday with WAA snows...Sunday night may be below 0F even in NYC with 850s of -25C. Another clipper/miller B deal Monday with a swath of heavy snow. Then the cold returns and a big storm looms around Super Bowl. Long range has a weak warm up and then a major arctic blast nationwide with a 1056mb high coming up of Alaska.

That's the Day 14 , see how the trough is furthest east , than yesterdays day 15 I posted , another few runs and  this shot on the maps will be really cold , Day 15 on the 0z ensembles are cold , we are not out of this through Feb 6 ,  GFS feb 5 - 15 below normal , this is goin to rival the greatest cold outbreaks we have had .

 

Both in ferocity and longevity

The weeklies are in pretty good agreement with JMA. Both of those pieces of guidance beat

the GEFS in predicting cold this week while the GEFS was warm back on 9th. The record

breaking Pacific block that got started in 2013 retrogrades a little back to Alaska keeping

the -EPO while the PNA falls back to negative territory.

Now if it look at the 2 temps that cold all those connected high heights over the top is Dec like.

Week 3 and 4 on euro ths yr has been bad this year

Only reason I buy the gradient pattern us because it agrees w the Jma

Which has been great.

Think the trough is too far west week 3 and 4 anyway .or did that in Dec w the same Pos height anomalies in Dec

So beware cold the u th 15th

The Euro weeklies and ensembles have been good through week two on the 500 mb anomaly center placement

and areas of above and below. I agree that past week two its effectiveness declines and the JMA has been

doing great for the monthly and seasonal range. The JMA was all over the eastern trough in January

since at least November 17th.

Im making a bold call that this pattern just begs to produce something downright historic from DC-BOSTON. PB GFI couldnt of been more correct when he said it wants to snow. Prime example was yesterday as the pattern overall argued against yesterdays storm. Im firmly believing that super bowl week or super bowl weekend we may be staring down the gut of a beast of an east coast LP system
