packbacker Posted February 13, 2015 Share Posted February 13, 2015 The euro was close to this type track. All the people moaning about the supressed track can now watch the MA go nuts. Link to comment Share on other sites More sharing options...

Buddy1987 Posted February 13, 2015 Share Posted February 13, 2015 Hr 99-102 850 and 2m like right over I-40 it looks like but with that heavy of precip coming down one would think regardless some wintry weather for sure around 85 and north?

superjames1992 Posted February 13, 2015 Share Posted February 13, 2015 rain for raleigh at 99 Everyone east of I-77 goes over to rain at some point. Sometimes, you just have to have a chuckle. It would still be a nice hit here and along I-85, though. Link to comment Share on other sites More sharing options...

RaleighWx Posted February 13, 2015 Share Posted February 13, 2015 Quite the range of solutions still out there today. At this point lean on an ens blend till we see more consistency.

GFS is alllllll over the place. yea, gfs has waffled like crazy the past 48hrs. at least it showed improvement over its ridiculous suppression of the 1st wave. other guidance has remained fairly steady, although the north trend of the low may be for real and is worrisome.

South_MountainWX Posted February 13, 2015 Share Posted February 13, 2015 It's a little worrisome 18z Gfs. It still gives me a good half foot but to much more north will really screw us temp wise. (McDowell county) But overall im still confident in a moderate event. Link to comment Share on other sites More sharing options...
Lookout Posted February 13, 2015 Share Posted February 13, 2015 The gfs is all by itself as far as how warm it is at the surface. It continues to completely ignore the single digit dewpoints in place before precip starts and shows essentially NO evaporational cooling to speak of which is absolutely absurd. It has precip arriving here monday morning. Surface temps are below freezing..yet despite dewpoints as low as sub ZERO in most areas, there is essentially NO temp drop. in fact temps RISE after precip starts. I'll kiss every ass on this board if that verifies. I mean look at this..dewpoints at 06z and 12z monday. Precip arrives between 12z and 15z....yet temps rise to the mid 30s. Ideally we would like to see heavier precip than it's showing to fully take advantage of the low dewpoints/dry airmass but even though the initial precip is light, it's virtually impossible to see temps rise with wetbulbs so low and dewpoint depressions so high. And the fact is these dry and cold conditions exist throughout the ENTIRE boundary layer..its' not just the surface..so there is no basis at all for not seeing a temp drop. i think i can safely say you can toss it's surface temps in the garbage throughout this system.

Stormsfury Posted February 13, 2015 Share Posted February 13, 2015 I know there are some that have waiting on what I might think might happen, well, this is the year of the nearly unforecastable winter it seems. I thoroughly believe one thing with this airmass for Sun-tue. It's bitterly cold, it's bone dry and diabatic processes will likely enhance the chances of keeping a cold pool in the region. It might even develop a small meso-high. Anyway I think the GFS is still warming things way too quickly here. Edit: after seeing Lookout's TD graph_, now I KNOW the GFS's warmup is full of crap.

burrel2 Posted February 13, 2015 Share Posted February 13, 2015 I don't think it's been mentioned that the JMA was very nice. It drops .5 to .75 of liquid on Monday Night/Tuesday morning for all of GA/SC/NC and the 850 line never crosses I-85. Link to comment Share on other sites More sharing options...

LithiaWx Posted February 13, 2015 Share Posted February 13, 2015 Just want to add a note of caution here, it is the 18ZGFS for crying out loud The 18Z GFS has equal verification scores to the 12,0, & 18 Z runs. This is a misconception that is debunked a few times a year. Link to comment Share on other sites More sharing options...

SnowNiner Posted February 13, 2015 Share Posted February 13, 2015 I don't like the GFS's solution, but it (or worse) is not off the table. Not by a long shot. Grit posted the 12Z ensembles a bit ago and for GFS/CMC/EURO and they ALL had a nice location of that high in the NE. It looks like it scoots this run and that's probably the difference. As long as the ensembles keep them there I think we're still in good shape. I do like the fact this run tapped the baja energy. Link to comment Share on other sites More sharing options...
burrel2 Posted February 13, 2015 Share Posted February 13, 2015 18z NAVGEM is a Biblical ECS for Upstate SC and west/central NC. wowza!!! Edit: Best I can tell the Jackpot zone would be just to the Northwest of Charlotte where it dumps about 1.25 inches of liquid all in the form of snow... That's pretty impressive considering the NAVGEM's dry/warm biases. Link to comment Share on other sites More sharing options...
