stormtracker Posted November 5, 2012 Share Posted November 5, 2012 I've never driven a bus before. Hopefully I don't run into a wall. I'll give you the keys for this one and let you drive. You should feel honored, I don't let just anyone drive the bus. Link to comment Share on other sites More sharing options...
mappy Posted November 5, 2012 Share Posted November 5, 2012 I'd love for you to get tons of snow, wind, etc, power loss and structural damage, so you can feel great about your back yard. Yes, because Ian was dead serious in his post. Good grief Link to comment Share on other sites More sharing options...

Bob Chill Posted November 5, 2012 Share Posted November 5, 2012 12z on the left and 6z on the right. Hr 45/51. You can see the nam starting to dig and sharpen. That is our key (stating obvious). If the GFS starts showing the same trend then it's time to really decide how "right" the euro is. Link to comment Share on other sites More sharing options...

dtk Posted November 5, 2012 Share Posted November 5, 2012 I got blasted for crowning the Euro king before Sandy eventually verified its solution. So I wont claim a victor early again. It seems the Euro is just more capable of handling blocky patterns. It has not wavered from keeping the storm close to the coast. Please, you did not get blasted. I simply pointed out to wait until verification to make some of the claims you were touting. The Euro handled Sandy better than the GFS, particularly for lead times from 5.5-8 days out.....though the GFS/GGEM actually did quite well (particularly in catching onto the idea of a significant westward turn in the track....instead of hugging the coast). Adam is right about the potential fool's good in terms of using Sandy as justification/track record. The GFS actually had smaller mean track errors for TCs in 2012 for most lead times....which likely has little (no) bearing on forecasting winter storms this year.

Heisy Posted November 5, 2012 Share Posted November 5, 2012 Yea NAM really dug the backside energy farther southwest. That's what this storm is all about. It's an obvious trend towards EURO. Link to comment Share on other sites More sharing options...
Bob Chill Posted November 5, 2012 Share Posted November 5, 2012 We're all in this for exciting weather. Sunshine kills plenty of people. Yep, there are zero exceptions to exciting weather. Collateral damage doesn't even come into the equation. If you are a true enthusiast (most here are) then you never waver even one millimeter. You root for the most exciting outcome 100% of the time. And that's totally fine. God will forgive us. LOL Link to comment Share on other sites More sharing options...

The GFS actually had smaller mean track errors for TCs in 2012 for most lead times....which likely has little (no) bearing on forecasting winter storms this year. I've actually found (empirically) that the errors and biases for TCs have tended to carry over into the winter for major winter storms. Probably has to do with the convective nature of both types of systems. Or I am mistaking noise for signal. Link to comment Share on other sites More sharing options...
TalcottWx Posted November 5, 2012 Share Posted November 5, 2012 High confidence for a noreaster. Medium for elevation snow. Low for metros. Anything else at this point still ill advised at this time frame. Link to comment Share on other sites More sharing options...

Probably has to do with the convective nature of both types of systems. Or I am mistaking noise for signal. Interesting, given how different the scales are (Sandy excluded)....though I suppose it is possible. I believe that we have started computing tracks for extratropical/midlatitude systems...I will have to keep an eye on this winter to see if the mean errors correlate at all with the 2012 tropical track errors.

WxUSAF Posted November 5, 2012 Share Posted November 5, 2012 Just a reminder for everyone who is hemming and hawing that surface temps might only be 32-35F if the Euro verified. It DOESN'T MATTER if the snowfall rates are high enough. I don't care if it's 70F on Tuesday (which of course it won't be). If the rates are high enough, the snow will accumulate some on grassy surfaces in particular. I had over 10" from the "PSUHoffman" storm back in 2011 and my temp was 33F the whole time. Particularly in this situation with a marginal, nearly isothermal airmass below 850, we'll probably wetbulb down to near 32F and then latent heat release from melting will stabilize us right around that point. Ratios will obviously be piss poor in this situation, but who cares? It might snow in the first week of November. I'll deal with 5:1. Link to comment Share on other sites More sharing options...

We've seen it over and over and over. Low 30's = snow on roofs and grass. Within 1 hour after it drops to 32 it will stick on the streets. Previous day's weather has virtually zero impact.

Ender Posted November 5, 2012 Share Posted November 5, 2012 The thing that bothers me about the Euro's solution is...we've seen this before. Just a couple, or a few, time blurs together as I get older, years ago the Euro underwent a significant resolution upgrade and literally weeks after it was insistent on developing at first a closed, then a cut-off, system. The first several days picked the region just off of ORF for explosive cyclogenesis. Then, within the 72-hr range the Euro was trying for the immediate DE coast, while cutting and stalling the system. The GFS jumped into the game for a single run or two, but that was it. Ultimately I think eastern New England got pounded. I don't think it came to its senses until about 48-hr ahead of the storm. I don't have the maps, but I seem to remember a dearth of cold air then too along with a ridge axis that was too far east for comfort (this one's even further I think), and a screaming 200mb flow that looked like it basically wanted to make the plains state ridge all but topple over into the Great Lakes. This isn't as extreme, but it's too similar, and so lacking in both precedent and other model support, that it's difficult to buy... Link to comment Share on other sites More sharing options...

Ian Posted November 5, 2012 Share Posted November 5, 2012 Valid to be concerned about the Euro overamping. It's done so at least a handful of times in recent winters. However all the globals have a big storm for the most part. GFS is so often east in this range it's hard to say its any more right than the Euro. IMO you should weight the Euro/ens at the point where we currently sit. Link to comment Share on other sites More sharing options...
WxUSAF Posted November 5, 2012 Share Posted November 5, 2012 I find it a little odd that the Euro has the cold surface despite a warm low-level bias and the GFS is warm despite a low-level cold bias. Link to comment Share on other sites More sharing options...
