HKY_WX Posted February 24, 2015 Share Posted February 24, 2015 NAM just dropped 13 inches on rdue. Link to comment Share on other sites More sharing options...
Shawn Posted February 24, 2015 Share Posted February 24, 2015 NAM even warms up a lot of NC. I don't love seeing this look after the SREF came in with a lot of warm members. What a nightmare to forecast so close to the event. If a forecast busts in either direction for ATL, it's going to be quite chaotic around there. That's the biggest problem area I see now of course. Areas of NC do try to warm.. Link to comment Share on other sites More sharing options...
burgertime Posted February 24, 2015 Share Posted February 24, 2015 12z NAM another crush job for RDU. Not worried about thickness on this run? Looked like a lot of sleet...but I guess that will be overcome with cooling. Link to comment Share on other sites More sharing options...

WidreMann Posted February 24, 2015 Share Posted February 24, 2015 NAM is not the run RDU wants to see. Raging sleet storm...yikes.I don't know what to believe. 00z Euro with 1-2" and NAM with piles of sleet. WTF? At least the 06z GFS was beefier.

superjames1992 Posted February 24, 2015 Share Posted February 24, 2015 Not worried about thickness on this run? Looked like a lot of sleet...but I guess that will be overcome with cooling. The verbatim skew-Ts look okay there, though the warm nose around 750 mb will have to be monitored. Not far from disaster for them, but that's where you have to be to score the jackpot. Of course, our warm noses are always served piping hot, so it would not be surprising to see the warm nose underdone. Link to comment Share on other sites More sharing options...
PackGrad05 Posted February 24, 2015 Share Posted February 24, 2015 This is when meteorology outweighs modelology... Having experience in this area gives you a lot of insider knowledge into what is actually going to happen.. That's why I'm going with more rain than snow for RDU. Rain to begin with, changing to some snow...1-2 inches. Link to comment Share on other sites More sharing options...
Lookout Posted February 24, 2015 Share Posted February 24, 2015 I think the upstate of sc has a good chance of seeing thunder snow Wednesday night. I've wondered myself if someone could, especially if you look at the nam. It pretty much brings an axis of convection through ga/sc. probably over done though NAM is warm for north GA the nam and it's sref are sort of by themselves right now with the rest of the guidance. euro and gfs ensembles, canadian, uk, etc all are south of the nam/sref and much more reasonable with it's waa pattern as the nam is probably overdoing it. If there was other model support besides the nam and it's ensembles/sref then it would be a cause for concern for sure for north ga/sc and parts of nc..but if the rest of the 12z models come in similar to last night, i'm not taking anything it's showing seriously. I just turned on the tv to see what WSB was saying. Minton showed a series of rough maps for tomorrow afternoon that clearly showed a frozen mix falling in the north ATL metro counties (Cobb, North Fulton, Gwinnett, etc.) by 5pm. I'm not sure where you got the impression she was calling it a rain only event for ATL. I mean her map did show rain, but that rain was generally south of I-20 at 5pm, which I don't think anyone here would argue vehemently against right now. Anyway. Smart people need to get off the roads in N ATL tomorrow by midafternoon. Hopefully that gets communicated really well as today and tomorrow progress. I didn't say she did, i was talking about the dude on nbc/channel 11. He flat out said he thought atlanta would see mainly rain with it being dry north and west of town.

RaleighWx Posted February 24, 2015 Share Posted February 24, 2015 Not worried about thickness on this run? Looked like a lot of sleet...but I guess that will be overcome with cooling. You always worry about something with winter weather down here I looked at soundings for my house in Youngsvile, and we stay all snow. The 850/925 lines hang just south/east of RDU, so i assume they are mostly snow, maybe some sleet at height of storm. Of course any more NW trend we would worry about sleet. But I do think the NAM/SREF members are too amped so probably overdoing it,, therefore this is the warmest/most NW outlier at the moment in my opinion.

Pilotwx Posted February 24, 2015 Share Posted February 24, 2015 Knowing my area in the N Foothills we can probably expect totals to go up if tacks as being modeled. Orographic lift usually comes into play. Link to comment Share on other sites More sharing options...
DocATL Posted February 24, 2015 Share Posted February 24, 2015 Ol' Chester...yeah...Really made no sense at all based on what FFC has said and also what numerous other model suites have shown.That's alarming. The fear of busting a forecast should not supersede the responsibility to the public. One would think. Link to comment Share on other sites More sharing options...
burgertime Posted February 24, 2015 Share Posted February 24, 2015 Yeah, it was very close verbatim for RDU. Bummer for CLT though, a lot of rain...yikes.. CLT looks fine to me. During the bulk of the precip 850's are cool enough and thickness looks better than RDU. Link to comment Share on other sites More sharing options...
sparklecity Posted February 24, 2015 Share Posted February 24, 2015 Alright, I'll go ahead and throw these dirty words out there. I'm a little worried about convection along the gulf coast robbing our moisture. Should I be? Link to comment Share on other sites More sharing options...
RaleighWx Posted February 24, 2015 Share Posted February 24, 2015 I don't know what to believe. 00z Euro with 1-2" and NAM with piles of sleet. WTF? At least the 06z GFS was beefier. Doubt it is piles of sleet. The warmest mid-level NAM sounding at RDU it gets to 0.2C at 800mb at FHOUR 45. Now perhaps it is greater in between hours, but I think heavy snow rates would overcome that Link to comment Share on other sites More sharing options...

Yea just looked at the output and it looks like RDU is gonna jackpot this one. That will be a raging heavy snow...hell CLT can probably pull out 8-10.

strongwxnc Posted February 24, 2015 Share Posted February 24, 2015 Same here. Sounds through 42 only go up to .4 at the surface. 850's are well below. CLT looks fine to me.

PackGrad05 Posted February 24, 2015 Share Posted February 24, 2015 This is the first time we've seen model trends going into the "warm" area.... we will have to see if it continues. Another 24 hours of model runs like that and most of the area will be more liquid than frozen. Link to comment Share on other sites More sharing options...
burgertime Posted February 24, 2015 Share Posted February 24, 2015 Hi-Res NAM cut down on totals for much of NC....looks more realistic now. .50 - .75 for most of WNC. CLT east is .75 - 1. RDU is still just over 1. of QPF. Link to comment Share on other sites More sharing options...

packbacker Posted February 24, 2015 Share Posted February 24, 2015 CLT looks fine to me. During the bulk of the precip 850's are cool enough and thickness looks better than RDU. No they don't. CLT has a huge warm nose, would be rain/sleet as 2m's are above freezing. Sorry bud. Link to comment Share on other sites More sharing options...
