metalicwx366 Posted January 24, 2014 Share Posted January 24, 2014 That is a copyrighted image, as are all WxBell maps, FYI. If it gets out into the public domain via FB or Tweeter, fine, link it, but the EC graphics from WxBell are off limits, no need for a JB vs American type deal. May I suggest wunderground, check out the precip, temps, and do the math. http://www.wunderground.com/wundermap/ Oh. Thanks I forgot about wunderground.

IN ADDITION TO MAINTAINING A THREE DAY STREAK OFHIGHS IS THE 40S...THE WARM ADVECTION WILL DRAW MOISTURE OVER NCFROM THE SOUTH...BUT FORECAST SOUNDINGS SHOW THIS AS MAINLY MID-LEVEL MOISTURE AT OR AROUND 10K FT. THE LACK OF MOISTURE DEPTH ANDDRY SUB-CLOUD LAYER SUGGEST THE LIGHT QPF GENERATED BY THE GFS AT12Z MONDAY IS OVERDONE. LOWS SUNDAY NIGHT WILL BE RELATIVELY MILDERCOMPARED TO PREVIOUS NIGHTS DUE TO THE SOUTHERLY WIND AND CLOUDCOVER....DROPPING INTO THE LOWER 30S. IF PRECIP WERE TODEVELOP...THERE IS A SMALL CHANCE OF A PTYPE CONCERNS BUT IT WOULDTAKE HEAVIER RATES TO OVERCOME AND WETBULB THE DRY LOW-LEVEL AIR.MODELS ARE IN DECENT AGREEMENT ON THE STRONG COLD FRONT MOVINGTHROUGH CENTRAL NC LATE MONDAY AFTERNOON AND EVENING...WITH THEUPPER TROUGH DEEPENING ONCE AGAIN AND SETTING THE STAGE FOR ANOTHERPERIOD OF TEMPS WELL BELOW NORMAL FOR THE MIDDLE OF THE WEEK.

LithiaWx Posted January 24, 2014 Share Posted January 24, 2014 Eastern NC is looking pretty good right now for snow. I would be a bit concerned along the coast but inland looks to do pretty well based on the current modeling. I would love to see this thing start up in the GoM and go Miller A on us. Someone please chime in regarding that being a decent possibility or wishcasting. I'm beginning to become a touch concerned for areas such as Atlanta and westward. If the models don't start moving towards a more favorable solution for us we could be on the outside looking in. Link to comment Share on other sites More sharing options...
downeastnc Posted January 24, 2014 Share Posted January 24, 2014 People laugh at the DGEX but I've seen the 0z GFS follow it's lead on more than one occasion. I do believe someone posted a clown map from the DGEX like 10 days before the Dec 2010 storm and it turned out pretty close area wise but overdone on totals ( of course) Link to comment Share on other sites More sharing options...
WeatherNC Posted January 24, 2014 Share Posted January 24, 2014 Folks from ATL to GSO, I would not throw in the towel by any means, for one, you never want to be in the sweet spot 5 days out as systems never verify exactly as modeled given the time step. Second, I see a good bit of evidence based on the GFS/ECMWF 200 and 300mb jet structure that could lay down concrete from Augusta to Raleigh, which has implications for areas along 77 down to Columbia, and further west. Just saying, still at that range where it could go to hell in a hand basket quick, but do not feel is the case this go around. Ens support stating that even with the variations at input and how they progress, consensus is there for a similar solution. Support for at-least some form of a coastal - offshore lp is high, GoM influence remains to be seen, Gulf stream baroclinic zone is a no brainer imo. Granted, a more energized trough axis going neg tilt west of the MS will cut a low inland, this does not appear to be the case this go around. If the slp does trend over the next 72hrs closer to the coast, indicative of a more favorable but still pos tilted axis, look out given the cold core conveyor potential in place.

Steve (weatherfide) wrote the discussion today but not the long range discussion for FFC. I wish he had but they are basically in lock step with the GFS. I'm not feeling this one for us Marietta.

BIG FROSTY Posted January 25, 2014 Share Posted January 25, 2014 Well from where I bed down at night, I will need to have a HUGH shift west to even get some flurries, (which is still possible) I want throw in the towel until Sunday after 12z runs if it's not way west of current models by then, I'm slinging the towel!!!

WeatherNC Posted January 25, 2014 Share Posted January 25, 2014 No. This is brought up every month. 6 and 18z do lack a fresh RAOB ingest, imo, NCEP should put more effort towards computing power rather than running the Global 4 cycles a day.

Shawn Posted January 25, 2014 Share Posted January 25, 2014 We now have the following: Good Guys: GGEM, NOGAPS, DGEX, JMA, UKMET (possibly), Euro EPS. Bad Guys: GEFS, OP Euro, OP GFS At least for precip further inland. It is getting that time to worry a bit if 00z models aren't any better for the OP of both the Euro & GFS.

Not worried yet... let's see how things trend until Sunday. The "take-away" from today's runs are, for the most part, better than last night. The thing that I will be watching the most will be the trough axis and positioning as we head into the event. As was mentioned before, you do not want to be in the "sweet spot" right now. I will be pulling for the folks that don't normally see snow, but wishing that it pulls west as well. With the cold air available, most of the SE could get something wintry with this one.

With the cold air available, most of the SE could get something wintry with this one. That's just it for me at this point. I really want the guys that don't hardly ever see snow get just blasted. Even when the models seem to depict a more westward entry of the disturbance in the PJ, it doesn't translate good for anyone downstream. It looks like an all or nothing possibility with the "all" being the coastal solution and the "nothing".....well, that's kind of obvious. Over the years, Larry has shown the ideal set ups for this part of the world and this isn't the most favored set up. We want the low to track in the northern gulf and over to around Tallahassee, FL. If we have the block, that puppy rounds the corner and heads NE. We would be threading the needle with this system if it were to impact us. Just seems too many things have to go right but that is always the case I guess! Good luck to everyone though and maybe the EURO will bring good news to someone. This cold will truly be a waste otherwise. Link to comment Share on other sites More sharing options...
HWY316wx Posted January 25, 2014 Share Posted January 25, 2014 To me the trend is not our friend at this point. I am hoping every stinking one of you is right that it has just "lost it". I am not cliff diving yet but I would love to see something in the 0Z model runs with some SE love. Link to comment Share on other sites More sharing options...
WeatherNC Posted January 25, 2014 Share Posted January 25, 2014 I fully expect to see a DGEX clown map at some point this evening, James, Super. 72 precip, clown map still has not updated on NCEP, millage and verification may vary. Came across these "5-day forecast" Verification scores.. for 120 hrs out etc... lower is better. Somewhat indicative of the day 5-6 performers, ~120hrs, ECMWF, UKMET, GGEM and GFS are battling for 3rd and 4th. My confidence did go up based on the 96hr UK graphic Allan posted, 12z. That was the model I was really waiting on to say this is legit. Expect the perturbations for the next 48 hours before things settle back down, maybe not as extreme as some guidance has suggested, but shovels should be at the ready nonetheless. Do not discount the NAM even at 72-84, if H5 is similar to the EC it is pretty much a lock under 120. Link to comment Share on other sites More sharing options...
Poimen Posted January 25, 2014 Share Posted January 25, 2014 Just for a little fun, let's assume 20:1 ratios are possible with this storm given the depth of the cold...I'd be more than happy with .50-.75 qpf the DGEX is selling for central NC.

NCSNOW Posted January 25, 2014 Share Posted January 25, 2014 I will always remember the Dgex as The Henry M> from accuweather model. Him putting those Big Daddy tee shirts and clinging on that model. Just read where it showed a HECS Feb snow in the MA a few years ago before any of the other models. Anyway tonight the following is crucial to me in seeing if we can pick up on any trends, then see how they evolve throughout the Sat/Sun model cycle. 1) Euro ensembles (most dependable/consistent IMO at identifying pattern/potential Day 3-7). 2-a) Euro op to see how it jives with it's ensembles. The euro op & nam agreeing with each other inside 84 (E/E rule) are hard to bet against. Euro has tendency to overplay 2m temps as colder and underplay qpf. Also has bad habit of holding energy out in the 4 corners to long. But imo it's still the king in winter for mby. 2-) UKMET (Has a great reputation of sniffing out N/S stream phased storm), Learned this tidbit from a graphic WeatherNC posted back on eastern several years ago. 3-a) Crazy uncle & JMA just to see if they give voice of confidence to euro op/ens and ukmet. 3-) Last the GFS. I have such a hard time trusting this thing in the mid range. It's like it goes through this 24-36 hour cycle around day 4-5 of throwing every solution known to man against the wall to see if it sticks. In fairness it runs 4x's a day and opens itself up to swinging and missing. But it does become important to get on board around day 3. Link to comment Share on other sites More sharing options...
