Winter 2013-14 Pattern Discussion

Recommended Posts

Thanks to Steve and others for the great analysis. It is appreciated and is the type of interaction we professional people come to our board for.

As far as the next arctic blast, we will have to wait to see if the SE ridge is displaced with this one. Things are looking more favorable so hoping for the best.

As far as JB, his December forecast nationwide pretty much scored an ace. It's tough work and yes he makes his living off of commerical energy clients.

The Accuweather winter forecast has also been spot on so far this year. I hope the Accuweather forecast does not hold through mid January, as if it does, we are skunked.

I see we still have the Jan.3rd potential. Another plus is that the CPC has removed the drought development for much of NC north of Charlotte in the seasonal outlook. Another downside is that they have above normal temps for the Jan-Feb-March period in western NC.

 

If anyone has noticed, this stormy pattern we have been in keeps occurring on the weekend. Absolute washout in some areas or small winter weather events if you go back even further in western or northern NC. Maybe the winter weather threat next weekend has some merit based on this pattern, and maybe more so since we have some cooler air around.

 Based on longterm climo as well as a higher tendency toward CAD in recent weeks, I do think that we have a higher than average major ZR threat for this winter. I say that because we're now barely into the neutral negative ENSO phase. My study of major ZR's in the ATL area has shown that the neutral negative ENSO phase has been the most common ENSO phase by a sig. margin. We'll see. The overall pattern does suggest at least an interesting pattern in early Jan. as far as watching for a possible wintry precip. threat of note for a good portion of the SE US.

Jan 2-4 still looks like a viable threat, at least as viable as a threat can be at this distance. The day 5 GFS 500 MB map shows ur system slowly approaching CA while blocking is beginning to take shape over the arctic. It's going to take at least another 5 days or more to get that system to the east coast...if it survives.

Great Graphic on March temps! Thanks Dacula! Really shows what happened when the pattern flipped and the

cold set in. Apparently, to many folks, if it does not lead to snow in their BY it does not matter. Nearly

as if it did not happen. Also, as others have mentioned, when SSW does occur, my understanding is that it is not a slam dunk for us to get cold. As I understand it, there is always the chance that the vortex slides to the other side of he pole. It is beginning to look as if we may have all of our ducks lining up for us as we end the year and head into January. As usual, I doubt some will believe it until they see snow on the

ground. I think could be the most favorable setup we have seen since winter 10-11. Let's hope it produces

some great winter weather for the entire SE!

I've seen great patterns, with great cold, give me squat..... and bad patterns, with marginal cool, produce great storms.  Nothing is written in the south, not Ga. anyway.  Just have to wait and see, just like every year :)  And as one gets older, if one is lucky, it is possible to have the same great expectations every winter, afresh, and yet not expire when they aren't realized :)  It can lead to baldness, however, and ground down teeth :)  T

It doesn't go out to 394.

Then my job here is done.

But seriously, I don't think posting these extremely long-range images contributes anything to the forum. They have no skill and just create unnecessary weenie-ism, which this board already has too much of. At least keep it inside of 240 where we can compare with the Euro and the Canadian.

 For the GFS and Euro, 240 sounds reasonable. I recommend to keep it inside of 24 hours for the Canadian. ;)

I figured it was harmless due to its just temps and the cold is a major factor for the pattern change, at least it's not a snow or fantasy storm map outside 300. To me it's the same as posting an 500mb/temp anomaly map 240+, but I digress.
