ineedsnow Posted January 27, 2014 Share Posted January 27, 2014 actually made them worse up here but they are fun to look at.. I dont know if they would perform and different in your area Most mets and pro forecasters I believe will tell you around 48hrs and then inside from there although I saw today that they got an upgrade recently and have gotten some good verification scores for the northeast systems this year so..

deltadog03 Posted January 27, 2014 Share Posted January 27, 2014 Looks like .33" QPF of sleet around here, then .67" QPF of snow....THAT won't be fun on the roads.... so maybe 1.5" of sleet and 6" of snow or so?? Link to comment Share on other sites More sharing options...
MillerA Posted January 27, 2014 Share Posted January 27, 2014 21Z sref mean snowfall Check out @Wright_Weather's Tweet: https://twitter.com/Wright_Weather/status/427642474064920577 Link to comment Share on other sites More sharing options...
calculus1 Posted January 27, 2014 Share Posted January 27, 2014 The 21Z SREF was a huge boon to those of us on the western side of the state of NC (together with the 18Z GFS). I thought I'd add Hickory's plumes to the discussion. We have transitioned from a mean of 0.25 inch of snow at 03Z, to 2 inches at 09Z, to 1.5 inches at 15Z, to 6 inches at 21Z. Of course, it's a mean, so there are some large values still skewing the mean quite high with five members over 10 inches of snowfall. On the other side, there are two members still showing zero. Anyway, I think we get something out of this at KHKY (even if it's relatively small), when it's all said and done. Soon, we'll have the 00Z GFS to digest...

redteamllc Posted January 27, 2014 Share Posted January 27, 2014 ok, For the new folks in the room remember this does not run for free!! Their is a lot of work to keep this up and running Please do the subscription Drive and DONATE....... This is what keep it up and running year after year!!! DONATE Done. Thanks Americanwx!

Jon Posted January 27, 2014 Share Posted January 27, 2014 Well the 00z GFS Baja energy is completely cutoff at 15hrs at 5h, that's new edit: 18hrs it's no longer cutoff...not really any changes so far. Link to comment Share on other sites More sharing options...
deltadog03 Posted January 27, 2014 Share Posted January 27, 2014 Hr18 GFS looks about the same as the 18z run so far. Link to comment Share on other sites More sharing options...
JQPublic Posted January 27, 2014 Share Posted January 27, 2014 Yeah those sref plumes are as good as it gets. For RDU. 1 over 20 6 in the 10-15 range 9 in the 5-10 1 around 2 2 around zilch And RDU is on the west end of town. The city proper and Eastern burbs could get a tick more than the Airport.

packbacker Posted January 27, 2014 Share Posted January 27, 2014 Well the 00z GFS Baja energy is completely cutoff at 15hrs at 5h, that's new It did that a couple of times during the 18z run. So far through 18hr just a whisker of a difference, splitting hairs really. Link to comment Share on other sites More sharing options...
dsaur Posted January 27, 2014 Share Posted January 27, 2014 The NAM gave a Montgomery to Columbus to Macon line a nasty mix of freezing rain/sleet/snow before FINALLY switching to all snow. Not sure of the totals, but it didn't look pretty. The soundings I saw had Columbus with an ice/sleet storm for over 18 hours. :/ Scout out your hills tomorrow, that will be amazing sledding. Big hills down around Sprewell's Bluff, lol. Man, you are getting some of the best Ga can offer. You need to go buy a lotto!! Just as long as the 0z's hold serve.

SnowDeac Posted January 27, 2014 Share Posted January 27, 2014 Did I read correctly that the SREF uses 10:1 ratios in predicting its totals? Or was that just for the Wright Weather mean snowfall map? I'd imagine western GA/SC/NC would have potentially higher ratios through much of the storm. Link to comment Share on other sites More sharing options...
burgertime Posted January 27, 2014 Author Share Posted January 27, 2014 00z GFS says 18z was too good to be true. Probably gonna be a mix between 00z NAM and 18z GFS Link to comment Share on other sites More sharing options...
Buddy1987 Posted January 27, 2014 Share Posted January 27, 2014 @27 maybe a tad weaker with the northern stream energy and a tad east Link to comment Share on other sites More sharing options...
Wow Posted January 27, 2014 Share Posted January 27, 2014 00z GFS says 18z was too good to be true. Probably gonna be a mix between 00z NAM and 18z GFS Probably.. the southern wave is a bit more SW at 30 Link to comment Share on other sites More sharing options...

I'll have to find the hills, but only because I'm going to be working (after I was supposed to have the week off...). That's actually not a bad idea... Find where the good hills are so I can have some good live shots! ... If they let me... LOL! I want to go out and enjoy this snow. Unlike the ice storm back in 2011 when I had to work the whole event inside. Link to comment Share on other sites More sharing options...
packbacker Posted January 27, 2014 Share Posted January 27, 2014 already tell through 30 hours it's going to be a miss from 18z, souther energy getting left behind, oh well, looks like we got 18z'd Link to comment Share on other sites More sharing options...
Jon Posted January 27, 2014 Share Posted January 27, 2014 Probably.. the southern wave is a bit more SW at 30 Yeah and the northern stream is a hair east...not gonna do it, it appears. Link to comment Share on other sites More sharing options...

airmarci Posted January 27, 2014 Share Posted January 27, 2014 How do the models handle the baroclinic zones that can form between the Apps and the Gulf Stream? Dr. Gary Lackmann at NC State talked about this extensivly in MEA 443. The baroclinic coastal fronts had huge ramifications for precip accumulation during Hurricane Floyd and 1/25/2000 acoording to the research. Curious how much the baroclinic front will have on us this week. TCs interacting with baroclinic zones are a totally different animal. In these types of cases (i.e. extratropical cyclogenesis along a strong coastal baroclinic zone) the convective parameterization (CP scheme) a model uses can have a significant impact on the model solution. Mahoney and Lackmann (2006) studied the February 2004 event and found that the BMJ CP scheme (used by the old ETA/current NAM) generated a weaker coastal cyclone than actually occurred. You can tell when the BMJ is up to no good when you see spurious cyclonic circulations develop along the coastal baroclinic zone. Link to comment Share on other sites More sharing options...
rduwx Posted January 27, 2014 Share Posted January 27, 2014 That LP is still closer to the coast which is throwing more moisture further inland. EDIT: The sfc map looks real good! Link to comment Share on other sites More sharing options...
