SnowNiner Posted February 20, 2013 Share Posted February 20, 2013 It's so cold on the 12Z Euro, we've gone PEACH!! Looks like the +PNA and -NAO ridges are starting to touch each other. If we can get this look within say day 7 on the EURO/GFS I'll start getting excited. Link to comment Share on other sites More sharing options...
WilkesboroDude Posted February 20, 2013 Share Posted February 20, 2013 Short window but morning commute...esp. back toward Wilkes County. Any cold pockets...or 1 degree colder than forecast will make the difference for some...most here will still be in that cold rain though likely don't take verbatim. Blacksburg: Stay tuned...winter storm watches and/or advisories may be posted for Thursday night and Friday with later forecasts. Link to comment Share on other sites More sharing options...
griteater Posted February 20, 2013 Share Posted February 20, 2013 Why dry? Just because it's not showing a storm or because of the ridge axis placement in the west? The ridge axis looks good to me, I don't want it any further east, that would definitely blow. With that look, your shortwaves would be diving down from the northern plains into the deep south on NW flow.....more clipper-ish without the ability to turn the corner...but those details to be ironed out later as you know. The look you would really want is the western ridge pushed way up into W Canada with a southern stream underneath plowing into S California (Nino look) Link to comment Share on other sites More sharing options...
HurricaneTracker Posted February 20, 2013 Share Posted February 20, 2013 Ungodly early March cold outbreak per 12z Euro Days 9 and 10. If that verifies, stuff will die. Agree and agree. Once we get into March I'm ready for winter to be over! Link to comment Share on other sites More sharing options...

burgertime Posted February 20, 2013 Share Posted February 20, 2013 I'm with you Burger. This is a cold, but dry look....but I would always prefer to take my chances with cold air in my pocket...we'll see if it holds. Rather blocky would you say? That very much reminds me of Jan. 2010. Much like Jan. of 2010 any S/W coming out of the west just went straight to Cuba...I've always been a believer in that we will either score on the front or the back (calm down jburns) with this type of look. We'll see if the 00z holds serve. Link to comment Share on other sites More sharing options...
Cold Rain Posted February 20, 2013 Share Posted February 20, 2013 Yeah, a perfect prog is perfectly cold and perfectly dry there. But as y'all have said, the details can be figured out later. Tonight's run will probably show a totally different western ridge orientation anyway. Link to comment Share on other sites More sharing options...
franklin NCwx Posted February 20, 2013 Share Posted February 20, 2013 As usual the op euro is all over the map. Expect another solution at 0z. Or wait another hour to see if the much higher scoring ensembles continue to stay the course. Link to comment Share on other sites More sharing options...

griteater Posted February 20, 2013 Share Posted February 20, 2013 From CPC... 8-14 DAY OUTLOOK FOR FEB 28 - MAR 06, 2013 OVERALL, ONE OF THE MORE INTERESTING LATE-WINTER PATTERNS IN RECENT YEARS IS FORECAST TO EVOLVE OVER THE CONUS. THE ENSEMBLE MEAN SOLUTIONS INDICATE THAT THE CIRCULATION PATTERN FOR WEEK-2 WILL REMAIN SIMILAR TO THAT FOR THE 6-10 DAY PERIOD, EXCEPT WITH SOME EVOLUTION OVER THE EASTERN PACIFIC AND FAR WESTERN NORTH AMERICA. THE BLOCKING PATTERN EVIDENT DURING THE PRECEDING PERIOD CONTINUES AT NEARLY THE SAME STRENGTH INTO WEEK-2. THIS IS IMPRESSIVE CONSIDERING THE TENDENCY OF ENSEMBLE MEANS TO DAMPEN OUT ANOMALIES OVER TIME. THE FORECAST HEIGHT PATTERN OVER THE EASTERN PACIFIC REMAINS SPATIALLY SIMILAR TO THE 6-10 PERIOD, ALTHOUGH WITH IMPORTANT AMPLITUDE CHANGES. THE DEEP TROUGH IN THE GULF OF ALASKA IS FORECAST TO RELAX, WHILE THE RIDGE OVER WESTERN NORTH AMERICA INCREASES IN AMPLITUDE. IN ESSENCE, THE FORECAST HEIGHT PATTERN REDUCES TO A RATHER CANONICAL COMBINATION OF THE TRADITIONAL +PNA/-NAO HEIGHT FOOTPRINTS, AT LEAST FOR A TIME, AND THE TEMPERATURE OUTLOOK FOR THIS PERIOD NICELY RESEMBLES THIS COMPROMISE. THE GREATEST UNCERTAINTY IN THIS PERIOD INVOLVES THE PRECIPITATION OUTLOOK, ESPECIALLY ALONG THE WEST COAST. THE CLIMATOLOGY IN THE PACIFIC NORTHWEST IS STILL RATHER WET, SO A SERIES OF TRANSIENT SHORTWAVES MOVING THROUGH THE MEAN RIDGE POSITION PROVIDES AN INTERESTING FORECAST CHALLENGE EVEN DOWNSTREAM. AT THIS TIME, THE OFFICIAL OUTLOOK FAVORS ENHANCED PROBABILITIES OF BELOW-MEDIAN PRECIPITATION ACROSS MUCH OF THE CONUS. HOWEVER, A SYSTEM OR TWO MAY BE ABLE TO DEVELOP ON THE LEESIDE OF THE ROCKIES IN THE SOUTHERN PLAINS AND MOVE EASTWARD ON THE SOUTHERN SIDE OF THE MEAN TROUGH. THIS TILTS THE ODDS TOWARD NEAR-MEDIAN PRECIPITATION ACROSS MUCH OF TEXAS AND THE GULF COAST. ABOVE-MEDIAN PRECIPITATION IS FAVORED ALONG THE IMMEDIATE EAST COAST DUE TO THE PRESENCE OF A SLOW-MOVING UPPER-LEVEL LOW THAT COULD SUPPORT ONE OR MORE OCCASIONS OF CYCLOGENESIS NEAR THE COAST. THE OFFICIAL 8-14 DAY HEIGHT PROG CONSISTS OF: 15 PERCENT OF TODAY'S OPERATIONAL 6Z GFS CENTERED ON DAY 11...15 PERCENT OF TODAY'S 0Z GFS ENSEMBLE MEAN CENTERED ON DAY 11...25 PERCENT OF TODAY'S 6Z GFS ENSEMBLE MEAN CENTERED ON DAY 11...30 PERCENT OF TODAY'S 0Z EUROPEAN ENSEMBLE MEAN CENTERED ON DAY 11...AND 15 PERCENT OF TODAY'S 0Z CANADIAN ENSEMBLE MEAN CENTERED ON DAY 11. FORECAST CONFIDENCE FOR THE 8-14 DAY PERIOD IS: ABOUT AVERAGE, 3 OUT OF 5, DUE TO GOOD AGREEMENT AMONG ENSEMBLE MEANS AND DERIVED TOOLS, OFFSET BY UNCERTAINTY IN THE DETAILS OF THE PRECIPITATION OUTLOOK.

tnweathernut Posted February 20, 2013 Share Posted February 20, 2013 I really would like to see the ridge and trough axis a little further west on the Euro ensembles. With an NAO progged to be that negative, it would be pretty easy for anything to take the lower road. The trough axis as shown on the OP would yield enhanced potential for the central and eastern Carolinas. Centered further west, would yield potential for MANY more in the southeast and midsouth.

Tacoma Posted February 20, 2013 Share Posted February 20, 2013 I am not real excited on the Feb28/March 1st storm that has been showing up, probably the week after is a better chance, if the pattern holds. We need that low over the lakes out of the way and all models are showing it rotting away around Feb28/March1st. well here we go again, every time the storm we're watching that looks to be a good one always seems to die out or get weak. guys I don't think we're going to land a decent snow storm. when its time for that storm to show up we say oh we like the next week, we're running out of weeks. we've got to get one of these good looking storms to stick.

We're looking at possible storms out past day seven. The models are just not that good. All we can do is look at the pattern. Once a storm sticks or appears within day seven, we'll have something to track. I do like the look ot this pattern. Somebody (outside the mountains) will get snow if the pattern depicted occurs.

Potential extreme period of blocking showing up. I'm excited over the pattern but it seems the snow storm that shows never seems to stick, all I want is one to stick before we run out of time. i know in the mtns.we are good until April and maybe the middle of april but your definitely about out of time then here.

SnowNiner Posted February 20, 2013 Share Posted February 20, 2013 If you can't get excited over the upcoming projected pattern then I don't know what would excite you. Potential extreme period of blocking showing up. Optomistic. Frankly I don't understand what features to look for for a storm to form or when moisture should appear or when cyclogenesis will or will not form in the gulf. I'm relying on this board to help me along. What I do know, if we have good blocking which seems to be forecasted clearly in the models, if we get a storm...it's coming our way instead of Ohio. Thus we're in the game. So first week of March, we're in the game. CLT may be on the bench watching the mountains get a storm, or it's cold and dry, but we're in the game!! Most of the winter, we haven't even been allowed in the stadium. Link to comment Share on other sites More sharing options...
POWERSTROKE Posted February 20, 2013 Author Share Posted February 20, 2013 from the looks of this map all of nc would be a nice snow storm. If we get too much cold air it will stay dry. Link to comment Share on other sites More sharing options...
griteater Posted February 20, 2013 Share Posted February 20, 2013 from the looks of this map all of nc would be a nice snow storm. Just to clarify, on that map, the 'L' on the GA coast is representing low 500mb height anomalies (i.e. the area of max negative 500mb height anomalies). It's not a surface low. That's just a large, cold vortex / trough over the eastern U.S. Link to comment Share on other sites More sharing options...
Bevo Posted February 20, 2013 Share Posted February 20, 2013 If we get too much cold air it will stay dry. There's a fine balancing act here...we need that cold/dry air in place for more than one reason: (1) Surface temps - albeit overly dramatic in it's argument, there's no question that colder soil temps mean longer lasting accums. (2) The Column - if enough legitimate cold air can press hard enough, it seems the battle to cool all layers is a little easier. (3) It's Already A Fight - moisture (warmth) is an immediate and ironic issue with our area and winter p-types. A cold/dry airmass in place allows for an easier fight from the on-set. Strong ULL dynamics may be exempt from this though. I would say that *extreme cold air will tend to stay dry and suppress too much. I would rather have solid cold air in place and let a potent southern stream evolve into chances for a higher probability of winter p-types materializing than the usual cold chasing moisture routine.

mackerel_sky Posted February 20, 2013 Share Posted February 20, 2013 Since both models have been showing at different times of the winter,these record cold looks only to not verify.I wouldn't bite on the extremely cold,supressed look.it will back off,imo Link to comment Share on other sites More sharing options...

franklin NCwx Posted February 20, 2013 Share Posted February 20, 2013 The euro ensembles are down right frigid from day 7 to 15. The cold is centered in the southeast just like the gefs show. The nao is in the tank too which is a very strong signal from 51 members. I see winter just keaps rolling on even tho the cries of bring on spring have been heard since dec. Does anyone have a temp departure map for feb?I think my area will have a below nornal month. Link to comment Share on other sites More sharing options...
