SnowNiner Posted January 8, 2014 Share Posted January 8, 2014 It seems like last year we had tons of northern stream energy coming through the base of the eastern trough, but it would just never dig enough to do the Carolinas any good. Always went north and west. Without something to suppress the storm track and a southern stream I just can't get too optimistic. I dont remember though how the pna was last year. Maybe it'll be enough. .... Link to comment Share on other sites More sharing options...
Cold Rain Posted January 8, 2014 Share Posted January 8, 2014 The index outlooks remain pretty much the same this morning, and you can clearly see it on the guidance. The PNA is likely going to go substantially positive, the NAO looks to be slightly in the no-help negative phase in the near term, migrating to postive later on, and the AO, after briefly going positive is shown to head south again. So with the Atlantic on vacation, we are at the mercy of the Pacific. The thing that is a little more encouraging, if the upcoming pattern after the warm-up is real, is that we're moving into our climo coldest period, the PNA ridge is looking better than it has so far, and we still have a lot of cold air on our side of the globe to be tapped. Without help from the Atlantic, we will still have to thread the needle, so to speak, but if the above factors are correct, then perhaps the needle's eye will be slightly larger.

One of the most important factors to me last year was that for most of the winter, all of the cold air in the NH was not on our side of the globe -- a stark difference from this year. I agree with you about energy cutting north and west. The location of the cold air doesn't really matter if that happens. But with a well-placed PNA ridge of adequate height, we can get a strong vort to pass south. Link to comment Share on other sites More sharing options...

Batman Posted January 8, 2014 Share Posted January 8, 2014 There's no indication in the teleconnections or stratospheric pattern that indicates that we'll be in a snowy pattern any time soon, if at all. We live in the SE. When can we ever say with confidence that we will be in a snowy pattern? There are ingredients present this year that many SE winters never have.

Batman Posted January 8, 2014 Share Posted January 8, 2014 You're taking things much too seriously. I'm really not. Sorry if my words read as if I am. It just cracks me up that some folks are doom and gloom negative about our winter weather in the SE. As if we are supposed to get snow repeatedly and the weather (and life) is terrible if we don't.

Brick Tamland Posted January 8, 2014 Share Posted January 8, 2014 The best thing about being in the SE is we know things can change in an instant. So far this winter has been terrible just like the last two. We have more cold this winter, but no snow to show for it. There is still time for that to change, though. We need a win badly.

He has no expectations for winter weather and doesn't get excited until snow is on the ground and falling from the sky. I have enjoyed the cold snap and the look of the upcoming pattern. I also enjoy discussing the possibilities along with that. Widre will play Devil's advocate and be correct 98 out of 100 times. He has history and latitude on his side.

RDU area is generally cursed lands. I agree, Roxboro does fall within the Greensboro "zone". There seems to be zones that run SW to NE through the state. The zones are not always configured the same (can be North over South or West over East) but they're ussually present for most winter events. RDU ussually falls between(boarders on) systems that efect the west and sytems that effect the east. If there is a strong CAD we can get significant winter weather, but a weak CAD will ussually only help your area. This year we've had week CADs. Eastern storms are great for the coastal plane but can miss RDU. But sometimes we can be the sweet spot (like in 2000). The Christmas storm really looked like a two part system that was first west based and then redeveloped as a eastern storm. Looking at the accumilations there was a drop off over portions of central NC between heaver amounts over the west and east. Link to comment Share on other sites More sharing options...

And its not because of January 2000, it's because it's more normal for us to see snow than it's not to see snow, although the 90's and the past 10 years is starting to sway peoples thought process. Things will get back to the point where we see snow more consistently, maybe not this year but soon. Link to comment Share on other sites More sharing options...
Poimen Posted January 8, 2014 Share Posted January 8, 2014 240 hour 500mb prog from today's GFS. If we can't score with something like this then I give up. Of course, a -NAO might help.

Poimen Posted January 8, 2014 Share Posted January 8, 2014 unfortunately we wont score with that. Everything is too far east.

dsaur Posted January 8, 2014 Share Posted January 8, 2014 It doesn't look like the models understand that a torch is underway, and all of Jan is lost, and we'll probably have to wait until Feb late to see cold weather. Meanwhile, in sensible weather...that you can look out the window and see...the roller coaster continues. And more rain coming. All I want is a wetter than normal winter, and I'll take my chance that some cold air will find it. So far not....but the chances continue, and the misses aren't by much.

Cold Rain Posted January 8, 2014 Share Posted January 8, 2014 I think it's easy sometimes to get too caught up in specific things like where exactly the ridge axis is. It's true that you don't want it off the west coast or over the Great Lakes. But there is an acceptable range of where the ridge can be. If the flow is very progressive, it can be a little farther west. If it's blocked up, it can be farther east. You also have to take into account the orientation and amplitude of the ridge as well as the strength of the vort diving in. All of those things matter. You can't just take a snapshot and say, "if the ridge was farther east, we'd be in business" or whatever, without taking into account the other factors. In the example above, it initially looks promising. But 24 hours after that image, you get a flattening riding, being bombarded by additional shortwave energy, and a progressive pattern. The low pops over the Lakes and a strong High builds in and dives into the SE virtually assuring another temporary cold and dry pattern (see below). If there was blocking, if there was less energy in the flow, if the vort was stronger, if the ridge was taller/sharper, if if if if if, then the ridge placement in the image in Poiman's post could, in fact, be ideal. Who knows...most likely, 10 days from now, things will look a lot different anyway. I'm more interested in the 180 time frame at this point. It will probably turn out to be garbage, but it's worth watching IMO. Link to comment Share on other sites More sharing options...

Seeing the cold anomalies build over AK doesn't give me the warm fuzzies though, I am trying not to look at that. Lets hope that doesn't setup shop, with a +NAO and neutral AO if the ridging in the west get's beat down it could be game over, so far it seems all the models are holding onto that ridging though. Or am I being paranoid and you not worried about the AK vortex setting up shop? Link to comment Share on other sites More sharing options...
