Yeoman Posted December 21, 2010 Share Posted December 21, 2010 I know euro is "king" but is anyone else bothered that the euro has a big storm because it it slower with the progression out of the southwest, and the euro is knows for a bias of being too slow with energy out of the SW? I read about that in the weenie phrase thread. Link to comment Share on other sites More sharing options...

mitchnick Posted December 21, 2010 Share Posted December 21, 2010 Has there ever been to major weather models like this this far apart in its solutions 5 days out? Crazy let's not forget that the 8 Day super ensembles had 1/6/96 as an analog date several days ago last year had some big storm dates on the super ensembles as well today, HPC mentions their interpretation of Euro ensembles from last night had NESIS 4-5 type storm on it folks, these are the kinds of things that show up first before you get the medium range computers converging on the final solution no one can guarantee anything at this point, but this system certainly was being sniffed out by the longer range computers for days now which are just the kinds of signs we saw last year before the big events sit back and enjoy the ride and dismiss the GFS until it has substantial other model support Link to comment Share on other sites More sharing options...
Dr No Posted December 21, 2010 Share Posted December 21, 2010 18z GFS still cannot turn the corner and still faster than the Euro. http://raleighwx.ame...bTSLPp06108.gif Probably said 100 times by now but the differences on the GFS is just mind boggling compared to the Euro, GGEM, and Euro ensembles. There seems to be no logical reason of why the GFS is still soooo OTS and progressive based on the positioning of the ridge out west and the pig low. The GFS is well OTS before even the Euro solution would start to give us snow. Link to comment Share on other sites More sharing options...

Have been at work for 12 hours, and knew when I saw 18 pages on the 12z thread something was good!!...just a bit discouraging to see one very reliable model w a blizzard, and one model that is a popular tool, with some flurries. But I agree with you, and will sit back and enjoy. Thanks again Link to comment Share on other sites More sharing options...
Fozz Posted December 21, 2010 Share Posted December 21, 2010 As long as the GFS is virtually alone in its lousy, OTS solution, I'm feeling pretty good. I don't expect 18+ at all, but perhaps 6-10" if things go well, with over a foot in Philly and NYC. Link to comment Share on other sites More sharing options...
Kmlwx Posted December 21, 2010 Share Posted December 21, 2010 I'm okay with the GFS not being on board right now but I'd like it to start heading in that direction. Who knows? Maybe it's onto something... Link to comment Share on other sites More sharing options...
Scarlet Pimpernel Posted December 21, 2010 Share Posted December 21, 2010 Well, I suppose we all knew it was going to be a long and tense week. But man, solutions all over the place! It's disheartening that both the 12Z and 18Z GFS were veritable train wrecks. Not just for the possible storm this weekend, but even beyond that. I was hoping to see the 18Z at least pull more west with this storm, toward what the ECMWF had. Alas, no. I sure hope the Euro has not been out to lunch the last couple of days...HPC sure seems to be more in its camp as do several forecast offices from what I have seen.

Maybe it's onto something... if the Euro is correct in the evolution, and I believe it is because it has been leading the way in slowing everything down (never mind placement of features per se), then we are still 4+ days away from the system starting to effect our area and really, almost 5 days as the Euro brings the snow in just before 1PM on Sunday it is typical for the GFS to be ots when at this point WHERE STORMS REALLY HIT US! its when we're in the 5 day bulls eye when we always loose Link to comment Share on other sites More sharing options...
Dr No Posted December 21, 2010 Share Posted December 21, 2010 18Z Navy cuts off the southern wave and leaves it in the GOM. That's probably a good indicator that things won't be as progressive as shown by the GFS. Link to comment Share on other sites More sharing options...
Terpeast Posted December 21, 2010 Share Posted December 21, 2010 I'd be excited now if it wasn't for the Euro being wrong and the GFS correct for the Dec 19 (2010) non event. This is going to be a long week. Link to comment Share on other sites More sharing options...

Bob Chill Posted December 21, 2010 Share Posted December 21, 2010 Seeing that the big spread between the GFS and Euro is mostly due to the speed of the energy coming out of the SW, I guess I should concentrate more on that when comparing models instead of the final outcome right? I'm not nearly as good as many on here when reading models so I generally try to focus on something that is easy to understand and follow but also has a large impact on the overall evolution of a complicated system. In laymens terms: Fast = Bad and Slow = Good right? Link to comment Share on other sites More sharing options...

This is going to be a long week. Don't forget when the EC tried to take that pseudo clipper in from the Oregon coast to ND then SE through RIC, and, then, BOOM! DC was supposed to get 8" as the system essentially bombed out, briefly cutoff and drifted away....and it wasn't as if the Euro showed that for a run or two...it was pretty consistent showing the same thing for four or so runs.

In laymens terms: Fast = Bad and Slow = Good right? I don't know if this post is out to lunch, but I guess I'll find out. Looking just at the 500 maps for 66 hours for 18z GFS and 72 hours for EC 12z, it looks like the biggest issue is the speed with which the energy off the coast of Cal. comes east. At 48 h (EC) and 42 (18 GFS) it's in almost the exact same spot in AZ. It's the next 24 hours where the big change comes. The EC has it at or about Amarillo, where the GFS has it at or about OK City. From there the changes become huge. Wouldn't the degree of buckle in the flow ahead of this thing argue for it making it east slower? You and I are on the same page here. Maybe someone here can tell me if this makes sense. Link to comment Share on other sites More sharing options...

I'm of the opinion that the GFS is way too fast and weak with the wave and the Euro is too slow and strong with the wave. So the answer lies somewhere in the middle, probably a moderate event for midatlantic and northeast. I think the NAM will start to show that moderate event tomorrow. The models have certainly converged on a significant overrunning event for central plains states though over the coming days and QPFs look very good for that.

Ender Posted December 21, 2010 Share Posted December 21, 2010 Looks like it, per Don's post in the 12z model thread. As I commented there, it's amazing how uniform the GFS Op and ensembles are and all completely different from the Euro and its ensembles. I'd really love to see all the Euro's ensembles to really see what the parameter space is on them, but in general they obviously support the idea of a big bombing/near-bomb Hatteras-to-Benchmark snowstorm. Here's the 120hr OP and MEAN: And 144hr... Link to comment Share on other sites More sharing options...

The models have certainly converged on a significant overrunning event for central plains states though over the coming days and QPFs look very good for that. I was actually thinking about this earlier with the 18Z GFS QPF maps. Pretty big swath of .25 - .50 precip across the midwest but cuts off over WVA and leaves us with flurries. It isn't like this is a clipper and gets dried up over the mtns. I would have expected to see at least an overrunning event on the model even if the low does slide off the coast in SC. Does this happen because once the low approaches the coast the energy transfers and the overrunning is cut off? Even with the bummer of the 18Z GFS run I would still think we see 2-4" overruning in front of the low. The weenie in me is pretty optimistic about getting a coastal for the majority of the EC. Seems like this should be a more likely outcome given all the ingredients in place. MECS or HECS? Probably not but SECS is looking good for the weekend. lol Link to comment Share on other sites More sharing options...
clskinsfan Posted December 21, 2010 Share Posted December 21, 2010 You want Wes (usedtobe) to say "orgasmic." Trust me on this one. I actually had to work today. So I did not get to look at the models until now. Huge difference between the GFS and Euro. But what else is new? I would expect the Euro to back off a little bit as we go forward. It simply cannot model a stronger storm than 12z. The storm depicted is a monstrosity. Link to comment Share on other sites More sharing options...

I'm not convinced that #1 the upper mid-atlantic low sticks around that long to significantly influence our shortwave, or #2 that what appears to be a superenergized shortwave in california based on record rainfall and snowfall out west will be that easily weakened. But who knows we have two completely different solutions from the GFS and EURO, and it's goign to be interesting to see which one blinks first.

psuhoffman Posted December 22, 2010 Share Posted December 22, 2010 The GFS has been trending towards the Euro for 24 hours now in 2 aspects, speed of the system, and the more southern track of the low. The critical 3rd factor, earlier phasing is the one area it is not trending with us. If this had stayed a more west to east system we could have had a decent SECS without any phasing. Now we have the potential for a HECS but a huge bust potential and nothing. Tonight at 0z I would like to see some model guidance other then the euro move towards an earlier phase and closer to the coast track. I do not count the UKMET as its end result might match the euro but its way too far east initially to matter for us. Also the GGEM slides the low just a touch too far east before pulling it back in, allowing our area to miss out. The Euro is the only model showing the phasing early enough to get our area into a significant snow. Hope something else blinks tonight. Link to comment Share on other sites More sharing options...

If the models stay different what do you go with or will they eventually agree? Everyone likes the Euro because it shows a BECS. If it was the other way around, everyone would like the GFS. The models will generally come to a narrow consensus in the 48-72 hour timeframe. Even then the verification can be off a fair bit. Sometimes they all look relatively the same 5 days in advance but that is certainly not the case with this system. The picture will be more clear once the shortwave in the Pac is over land. Most on here don't buy into the GFS because it doesn't seem like a plausible solution considering the features in place. On the same note, it is hard to buy totally into the Euro because it shows an extremely rare event for the EC and goes against climo during a Nina. Most of the Mets on here seem to feel that the final outcome will be right in between the two. That would be fine for most on the EC. The weenie suicide hotline is going to light up if the GFS holds its solution tonight and the Euro makes a move in that same direction. Link to comment Share on other sites More sharing options...
