dendrite Posted December 27, 2014 Share Posted December 27, 2014 Just a reminder. Let's keep this thread free of the "woe is us" posts and save the complaining to the banter thread or the now derailed December thread. If you can't add something technical or not emotionally laden then keep it out of this thread. Pattern disco only. Link to comment Share on other sites More sharing options...
Typhoon Tip Posted December 27, 2014 Share Posted December 27, 2014 Even the Euro is doing this now...closing off a 594dm height node over the Bahamas. That's so funny... can't get that in June, but ... hell hath no fury when it comes to Christmas glee. Am I the only one that's giggling in my chair over this. That aside, that's gotta be some sort of particularly hot anomaly. Hmm Link to comment Share on other sites More sharing options...
Typhoon Tip Posted December 27, 2014 Share Posted December 27, 2014 This is incredible looking ... The EPO ridge is so dominating it appears to be blocking any cross-polar flow. Somewhat ironic because -EPO's usually support more of that. But here .. the shear size and girth of that beast (particularly in the GFS and GGEM) is really pinching the hemisphere off between Eurasia and this side of the hemisphere... Fascinating.

mahk_webstah Posted December 27, 2014 Share Posted December 27, 2014 Am I wrong to kinda like that look for up here?wouldnt be hard to envision cold enuf air winning that battle.

Damage In Tolland Posted December 27, 2014 Share Posted December 27, 2014 What are the scales there out of curiosity? I'm assuming the dark blue is 2-4 and lighter shade of dark blue is 3-5? Link to comment Share on other sites More sharing options...

I don't get what's so bad about what the massive -EPO ridge I mean if it does get mild on Jan 4th it quickly gets cold again a day later. Link to comment Share on other sites More sharing options...
leo1000 Posted December 27, 2014 Share Posted December 27, 2014 I am wondering too how this pattern will affect Nova Scotia Canada is this pattern good for us but bad for SNE?. Link to comment Share on other sites More sharing options...

I don't think Tip said there was anything bad about it at all. There's no mention of that being a bad thing...just a "wow" type -EPO. Link to comment Share on other sites More sharing options...

Well he mentioned it would dominate so much that the cross polar flow would be stopped dead in its tracks. Link to comment Share on other sites More sharing options...
CoastalWx Posted December 28, 2014 Share Posted December 28, 2014 Well he mentioned it would dominate so much that the cross polar flow would be stopped dead in its tracks. Yes it will at some point. Whether it's in BTV or RIC is to be determined. Probably a mix of both at some points. Link to comment Share on other sites More sharing options...

CoastalWx Posted December 28, 2014 Share Posted December 28, 2014 What about Nova Scotia? As its of course on the east coast. They run the risks of getting warm too because of your longitude, but you are also near the reservoir of cold. Link to comment Share on other sites More sharing options...
J Paul Gordon Posted December 28, 2014 Share Posted December 28, 2014 I think in the dreadful winter of 2001-2002 Canada was frigid while the warmth remained just south with us. Not sure it is an actual analog, but the picture looks similar. At least we get a few cold days out of this, if no snow. Link to comment Share on other sites More sharing options...

SnowGoose69 Posted December 28, 2014 Share Posted December 28, 2014 No, that winter was different. That was a big AK vortex. Yeah, complete opposite, this pattern right now is odd as many other Mets have said...I don't ever recall seeing that much of an EPO ridge and the SE US being so insanely warm....I've seen it transiently before such as December 1990 but that thing is there at least til around 1/4 or so.

It's a bit too far west for this pattern. That just causes troughs to dig S and even SW which then leads to fast gradient flow and storms that may ride into the Lakes. It does look like it will shift east at times which is why I'm hopeful to try and cash in after next week. Link to comment Share on other sites More sharing options...
J Paul Gordon Posted December 28, 2014 Share Posted December 28, 2014 I must be thinking of another winter.. can't recall, though. Cold air trapped in Canada... ferociously cold in Newfoundland, but quite mild here. So close but so far away. Anyhow, any chance that the too far west Alaskan ridge might budge east?

I don't think it will, it'll breakdown briefly or retrograde after 1/6 and then about 10 days later I think the MJO going into phase 7 builds us a classic west coast ridge Link to comment Share on other sites More sharing options...

Yeah I mentioned it tries to build eastward and poleward. That will try to bring cold southeast at times. It's a tough call. A 100-200 mile difference in the mean ridge axis in AK could mean epic snows or pedestrian. I think it's dangerous to assume one way or the other. We'll have out shots, that's all you can say. That day 8 event could very well be quite an icing deal in the interior. Link to comment Share on other sites More sharing options...

Anyhow, any chance that the too far west Alaskan ridge might budge east? 96-97 maybe, it was crazy cold in Canada and the upper plains, I think we had a similar problem with the ridge being way too far west over AK, and the NAO went positive in January and February after it was negative in December Link to comment Share on other sites More sharing options...

We evolved from a SE Ridge Pos NAO gradient into a snowy stormy month. The bridge jumpers are nuts Link to comment Share on other sites More sharing options...
