superjames1992 Posted February 12, 2013 Share Posted February 12, 2013 Just took a peek at SV maps...so suppressed I don't even think the coast gets flurries....cold as heck though, that's a mean trough. Well, bah. Figures. The Euro is kind of on its own now, though. The Canadian shows an Apps Runner, I believe. The NOGAPS shows this bizarre Miller B. The UK Met seemed to show some sort of Miller A scenario and the GFS, while weak, was definitely a decent storm in the Carolinas. And then we have the Euro bone dry. Let's see who wins, I guess.

John1122 Posted February 12, 2013 Share Posted February 12, 2013 Individual ens members have 3 of 12 showing not much of anything. 3 have accumulating snow East of the Apps, 2 of the 12 have accumulating snow across the N Miss/Ala/GA area, 7 of the 12 have Tennessee and Kentucky with accumulations.

FallsLake Posted February 12, 2013 Share Posted February 12, 2013 6z GFS continues to show a lighter event for NC and Virginia. Looks like a large part of NC receives 1-2 inches. At RDU qpf looks to be around .15. If there are higher snow ratios this could a little over 2 inches. But this was one of many more runs of the models; that will trend one way or the other right up to the event. The most important think at this range is that we still have something to track. I still think there is a chance of a more significant storm. Link to comment Share on other sites More sharing options...

beanskip Posted February 12, 2013 Share Posted February 12, 2013 This thing is trending away fast. GFS down to just a tenth of precip for most of NC and the western third is almost out of the action. Euro not coming on board and we are in its wheelhouse. It's odd, but the CMC is the only thing keeping my hopes up -- even though its way west it still means a middle of the road solution could bail us out. Starting to have that "bet the streak" feeling, though. Link to comment Share on other sites More sharing options...
burgertime Posted February 12, 2013 Share Posted February 12, 2013 If accupro maps were working right now I could tell you what the Euro EPS run showed on the the surface last night.

Poimen Posted February 12, 2013 Share Posted February 12, 2013 I suspect the trend will break one way or another with today's runs, either 12Z or 0Z. I think there is a fairly strong signal for a coastal storm of some degree to develop Saturday. The question is will it be out to sea, or will the H5 cooperate and give us something better. Hoping for the best as we near the end of yet another lackluster winter. Link to comment Share on other sites More sharing options...

superjames1992 Posted February 12, 2013 Share Posted February 12, 2013 The good news is that the shortwaves in question have not been sampled yet by the RAOB network. They should be tomorrow.

Cold Rain Posted February 12, 2013 Share Posted February 12, 2013 I'm actually happy to see mostly a late development at this point in time, especially when there's quite a bit of variability from the various modeling. That means that there is still a decent chance for a storm with a favorable track. As always, the odds are not that great. But if you're 5 days out and the consensus is a little late and a little east (along with a few solutions showing inland), that's a lot better than the consensus being strong and west, IMO. We're most likely not going to lock in on a major snowstorm this early and maintain that look for 4-5 days. So if that's the case, I think we have a fairly good scenario right now...although, it would be nice to see the Euro start to drop some hints of a favorable trend. Given that this is going to be mostly reliant on the northern stream and the messy flow up there, you've got to think that until the key energy is better sampled, we'll see a lot of variability -- probably at least for the next couple of days. Overall, I feel pretty good for at least some snow for NC. Right now, I'd give it a 4 in 10 chance we see something. Link to comment Share on other sites More sharing options...

Even then you could see variability. Lots of players on the cards right now. The variability in the guidance, however, one thing's relatively consistent is the very cold 850mb temperatures. Brief Winter Precip concerns are mentioned on KCHS's morning discussion this morning. One of the things that's completely different than last month (and all winter) is that the moisture faucet has been released across the region. I've picked up already since this series of systems has started over 3" of rain, and couple that with the 3.13" I picked up with the last system. The pattern itself is at least more favorable to produce, and I wouldn't be surprised in the least, as most events in the Southeast (Carolinas, GA) are generally poorly modeled, unlike the Feb 2010 event (except the GFS which took eons and finally caught on 48 hours from the event). Lots of players and I believe an RAOB sampling and data ingest is on the table. I think the players are on the table, just getting the guidance to key on the right players for the next couple of days means everything, but the pattern in my opinions favors something to occur in a much more active regime. .LONG TERM /FRIDAY NIGHT THROUGH MONDAY/... THE GFS CONTINUES TO BE THE MOST AGGRESSIVE WITH SHARPENING THEUPPER AND TROUGH AND DEVELOPING A SURFACE LOW OFF THE CAROLINA COASTON SATURDAY...WHICH PUSHES AN ARCTIC FRONT THROUGH LATER SATURDAY.THERE IS ENOUGH DEEP LAYER MOISTURE WITH THIS FRONT TO WARRANT ATLEAST SLIGHT CHANCE POPS...MAINLY AFTERNOON FOR THE NORTHERN HALF OFTHE AREA. GUIDANCE STILL SHOWING HIGHS IN THE UPPER 50S TO LOWER 60SAHEAD OF THE FRONT ON SATURDAY...BUT SUSPECT TEMPS WILL FALL DURINGTHE AFTERNOON DEPENDING ON THE EXACT TIMING OF THE FRONT. STARTINGTO GET A LITTLE CONCERNED FOR SOME BRIEF WINTRY PRECIP WITH THISFRONT AS BOTH GFS AND ECMWF DROP 850MB TEMPS TO -2 TO -4C BY 00ZSUNDAY...BUT BOUNDARY LATER TEMPS MAY BE TOO WARM.

It would make me feel infinitely better if the Euro would show a little of that variability. It's been remarkably consistent (since showing it's "bomb") in showing a non event (and a late bloomer off the Atlantic coast). I need to see it "blink" before getting excited for anyone, though like I have said all week....... if I were in the central Carolinas and points north and east I would keep my eye on it. There definitely are players on the field here. Link to comment Share on other sites More sharing options...
Poimen Posted February 12, 2013 Share Posted February 12, 2013 our V-day storm's attending cold front will create a baroclinic zone off the GA/SC coast later this week, which will be primed for LP development with the aide of the vigorous mid level energy coming down the pike. Overall, it's a pretty good set-up for a SE/Mid-Atlantic coastal storm (IMO). That's just how I see this pattern evolving, but I could be wrong.

Tacoma Posted February 12, 2013 Share Posted February 12, 2013 well lets hope this storm comes together. the cold air won't be a question this weekend if we can just get that to dig a little further south and phase with the energy out of the north this would be a good storm for the weekend for nc, upstate sc, n. ga n. al. maybe e.tenn.

eyewall Posted February 12, 2013 Share Posted February 12, 2013 It would make sense it is a bit testy in here with this being the last chance for most to salvage something (which of course slipped away a bit once a thread was created).

Shack Posted February 12, 2013 Share Posted February 12, 2013 Unusual and surprising to see this from the NWS in Peachtree City(KFFC). They must be buying into a wetter solution for Fri-Sat period. They have a 30% chance of rain in Macon on Saturday with a high of 50. They're so conservative that when they post "30% chance" of anything 96 hours away they are sure of the event and must have heard from God. LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...THE UPPER LEVEL SHORT WAVE FINALLY PULLS THE REMAINING PRECIP OUT OFTHE CWA WEDNESDAY NIGHT LEAVING A DRY FORECAST FOR THURSDAY ANDTHURSDAY NIGHT. FOR FRIDAY...A SHORT WAVE WILL DROP OUT OF CANADAAND INTO THE MIDWEST DEEPENING THE H5 TROUGH OVER EASTERN CANADA ANDTHE GREAT LAKES. IN RESPONSE AN ARCTIC FRONT WILL MOVE ACROSS THECWA FRIDAY NIGHT AND EARLY SATURDAY. MOST OF THE MOISTURE ASSOCIATEDWITH THIS FRONT WILL BE ALONG AND BEHIND THE FRONT. LOW LEVELTHICKNESS PROGS INDICATE A RAIN/SNOW MIX ACROSS MUCH OF THE AREAFRIDAY NIGHT AND SATURDAY...HOWEVER SURFACE TEMPS WILL KEEP MOST OFTHE PRECIP IN THE LIQUID FORM OVER MOST OF THE AREA...EXCEPT FOR THEEXTREME NORTH WHERE THERE WILL BE A RAIN/SNOW MIX. THE PRECIP SHOULDBE OUT OF THE CWA BY 00Z SUN. A STRONG NORTHWEST UPSLOPE FLOW IN THEMOUNTAINS SATURDAY NIGHT COULD HOLD MOISTURE AND LIGHT SNOW IN FOR ALITTLE LONGER AND WILL KEEP A 20/30 POP GOING FOR THE NORTHEASTMOUNTAINS SATURDAY NIGHT. IT APPEARS GUIDANCE TEMPS ARE COMING MOREIN LINE WITH AN ARCTIC AIRMASS...BUT THEY STILL APPEAR TOO WARM ANDWILL NEED TO DROP THEM A FEW DEGREES.MUCH DRIER AIR MOVES INTO THE CWA SATURDAY NIGHT AND SUNDAY AND THISWILL HOLD THROUGH MONDAY.
