Winter 2013-14 Pattern Discussion

The trough on the 00z Euro was just farther west. The 12z run it was farther east. At the end of the run at h240, Montana is maxing out the weatherbell scale at -48 degrees below normal for a 2m temp. (and it's pretty cold in Montana in December normally probably)

Like the mini-trend. Wow 48 below normal in Montana, I imagine your approaching 40 below depending on the locales.

We need moisture with the cold... When and if we get real cold there will be no moisture around! But now we can't time a system right to save our butts!!!!  cold/dry warm/wet etc.......

 

 

 

 

Fropa! Swoosh....

 

To be fair CR, you responded to the posted model with the exact same observation Frosty did, just with more meterological sarcasm... :P

Haha! I was wondering if anyone would notice. :) Steve might squeeze a little snow out of it, but it'll probably be rain then cold over in my neck of the woods. At least it looks like the cold is decidedly inbound, if that map is correct.

the big cold will shift east before christmas relax people,  am sure we will get our's .http://t.co/g9aLstH1ZE

 

I think the natural progression of things would argue for a more easterly trough setting up from the previous one, but I am not sure it will make a big difference overall for the Carolinas.  TN (middle and west), MS/AL could be a much different story, but in the end it could just be a major arctic blast pointed at Texas again, while never really getting to a point where it helps anyone east of the apps. 

 

I think that is the biggest possible option for this. Warm and wet out ahead of a major cold front and then cold cold cold (and probably dry) central plains/deep south into Texas, but modifying temperature wise as you head east.  In a nutshell, it looks like the setup for another glancing blow.

CPC, once again, offers no hope:

Won't bore you with maps or extracts. Open the link, if you are so inclined, and have your Rolaids ready  :sizzle:

Maps would could kind of imply the cold infiltrates the upper great plains and then just sits there.  I'm always skeptical of these, they seem to come around only after the models have locked on to a steady pattern look rather than indicate what's on the way.

 I'm always skeptical of CPC too in the long range, (reason for no maps or cut and paste of the discussion), but CPC is a factor for the prognostication equation; I'm looking for some factor that might get the deep SE folks a bit excited - just not seeing it (yet). Just sharing what I see. :~)

Believe it or not I'd be happy about that map if I was in the SE, it will get warm obviously, but thats one helluva arctic blast behind it.

Where are you located? I'm guessing VA? Yeah, looks to get a little nippy behind the front. Staying power looks weak, but hey, beggers can't be choosers.

GFS and Euro look great in the LR....this run. I have a fear we may be back to last year just slightly better. Go re read the December thread. Euro and GFS were constantly showing a pattern change sometimes with huge arctic outbreaks only for it to never happen. I want to see these changes going in at about 140 hrs and last until near the end of the run.

I'm with you. I need to see the whites of it's eyes before I believe it.

This isn't last winter or the one before that. A lot of the US  is already covered in snow and the cold that has been in the US as well. Yes we have missed the action in the SE so far but it is early .Not really even winter yet.

I agree. It's about as polar opposite as it can be so far this year as we head toward winter.

FWIW...18z GFS lays down a nice 850mb temp gradient roughly along I-20 with our next possible arctic plunge...something that to me would indicate that our pesky SE ridge won't be as pesky next time around. It won't be a total dive bomb of cold air to Florida but it would be plenty cold enough for those areas where any winter weather would be more likely to occur.

That's a nice little push Marion. Boundary along the GOM of 0C readings.

 

 

I do agree its a good push for those along the Gulf Coast...and for anybody to have any hopes on winter weather, you would rather the push be moderate. You don't want over-amplification (i.e. something that drives a cold front through Key West.)

 

 

The biggest thing I noticed on these model runs is that the boundary looks to take on an east-west orientation rather than SW-NE...a sign that the pig ridge is getting squashed more and more.
