TUweathermanDD Posted November 5, 2012 Share Posted November 5, 2012 Euro shifted east and weaker but it wasn't a huge move or anything. Here's msl hr51 12z and hr63 0z. We'll see where the trends keep going. I know Bob, people are going to overreact, and go solely via the models and thats their choice, but overall I think Baltimore up 83 look to be the spot for this one, and BWI to PHL will likely catch the deform band. The euro wasn't that much of a move. Link to comment Share on other sites More sharing options...
CoastalWx Posted November 5, 2012 Share Posted November 5, 2012 Again, you will need to be in that band, so a 30 or 40 mile shift is huge. This is why the forecast is so difficult. Link to comment Share on other sites More sharing options...
Ian Posted November 5, 2012 Share Posted November 5, 2012 Which is horrible. I don't see too much change in the 12z suite overall. The Euro bumped east in previous runs then came back west. This solution might be closer than previous but I wouldn't bet on it. No need for folks to have emotional swings every few hours. Safest bet is probably to assume you'll (global) get screwed if you want to do that. Link to comment Share on other sites More sharing options...
Ji Posted November 5, 2012 Share Posted November 5, 2012 its a horrible run. The euro folded like the redskins. Without heavy precip, there will be no accumulation...not even a dusting most likely Link to comment Share on other sites More sharing options...

aldie 22 Posted November 5, 2012 Share Posted November 5, 2012 Weatherunderground maps show Ji's house fringed...no snow for him...lol Full circle...made this post last week after a euro run gave the region snow but fringed mine and Ji's house...give it another week and it will come back Link to comment Share on other sites More sharing options...

WinterWxLuvr Posted November 5, 2012 Share Posted November 5, 2012 I guess location dictates opinion, but it's a pretty big shift. If it becomes reality, it's pretty hard to say that the Euro was "spot on" for this one. Granted, I've only focused on my area, but the GFS has had me fringed the whole time with this whereas the Euro had me bullseyed to begin with, even had a really good snow as recently as its last run, and now I'm in no precip at all, again much closer to what the GFS has shown the whole time. Anyway, we'll see what happens. Link to comment Share on other sites More sharing options...
Bob Chill Posted November 5, 2012 Share Posted November 5, 2012 I know it's a weenie statement but the atlantic off the se coast is still plenty warm. We need to pray for rapid strengthening so the deform band can set up. Euro came in weaker so obviously precip got a haircut. The storm could take the same more easterly track but be deeper and still give us a good chance. Many runs to go so we'll see. If I had to hedge I would go with a stronger vs a weaker system than what is currently being modeled. Link to comment Share on other sites More sharing options...

I do think this run sort of stunk for DC, but 00z tonight could come west again. Link to comment Share on other sites More sharing options...

I am going leaving for Orlando at 2:00pm Wednesday and it was killing me that the euro was showing this solution.i sorta feel better now. It would of literally ruined my year to miss this storm.

aldie 22 Posted November 5, 2012 Share Posted November 5, 2012 Just wait till the gfs comes west. Oy History says it will at least one time look like the big snow euro runs...we have all been on here long enough to know that...hopefully some of the weaker souls out there can handle that swing. I still see flakes in the air which is neat at this time of the year...I for one have no clue and will never pretend to know what the final outcome will be...still fun to track something then to not to Link to comment Share on other sites More sharing options...
CoastalWx Posted November 5, 2012 Share Posted November 5, 2012 Yeah it did, except for yanking the elevation argument away. I think it was you...or perhaps someone else on here. If push comes to shove, I'd rather be in a death band, then at 1000ft and have 20DBZ echoes. Death band > elevation. Link to comment Share on other sites More sharing options...

clskinsfan Posted November 5, 2012 Share Posted November 5, 2012 Lil too close there for comfort... Or completely out of the game for some of us. I still like having some elevation on my side if any moisture can make it out here. But that is starting to look unlikely. Link to comment Share on other sites More sharing options...

WinterWxLuvr Posted November 5, 2012 Share Posted November 5, 2012 Funny thing is, now that the Euro has wobbled right, the GFS ens members are the wettest they've been (again, I'm looking at my area). I guess there's time for development/change. Gonna be a long winter like this. Link to comment Share on other sites More sharing options...

psuhoffman Posted November 5, 2012 Share Posted November 5, 2012 I know we hate to hear this because we love to track and diagnose every piece of data that comes out, but this is the kind of situation where small details in the dynamics and evolution of the system will have a drastic impact on the actual track. The block is breaking down so there is much more "room" for this to track then with Sandy. This is also not an WAA driving event where picking out the thermal boundary will help lock in the storm track. This system is going to bomb out and small differences with exactly how soon that process begins as well as the evolution of that process and amount of convection involved will make big differences in the final location of the meso scale banding on the western side. We all know how these types of systems tend to continue to "change" on the models right up until nowcast time. I think this is a wait and see system.

CoastalWx Posted November 5, 2012 Share Posted November 5, 2012 Yeah elevation is helpful but only if you get precip I expect some classic model hugging for something that will come down to Nowcasting. It's all about that band placement. Hopefully Randy keeps his weather boner in check lol. Link to comment Share on other sites More sharing options...
Ender Posted November 5, 2012 Share Posted November 5, 2012 Pretty much everyone just modelcasts these days. Well, until humans can can hold billions of bits of initial state information in their working short term memory, and then perform trillions of iterative time-step calculations via some relatively complicated differential equations while also, mentally, handing the some fairly nasty coordinate system translations...that's probably going to be the state of affairs for forecasts further further than 24 hours in the future. From what I recall, the very best human forecaster's average 36-hr error was only slightly better than the average 72-hr error of the earliest medium range models. So...ignoring the models and hoping to beat them at the own game is probably stupid. Now, pointing out that a model appears to be repeating one of its past sins, while also lacking support of its peers and antecedent synoptics...is that "modelcasting" now?

stormtracker Posted November 5, 2012 Share Posted November 5, 2012 Just say no to model hugging. I'm with you 100% (for once). I almost wish super weenies didn't have access to models...or only once every 24 hours. The swings are crazy. I'd sit tight and wait for a little bit longer. I think I'm still on your bus with this.

I'm talking more about swinging with every run. A good forecaster can act as a super ensemble by meshing them all together and factoring in any known or perceived biases. Right now consensus is not terribly exciting for DC specifically but not much has changed either. I guess I'm not sure why this last run of the euro is so much more valid than the last four.. Other than a seeming growing consensus. I also don't think the public gets all this waffling done run to run or that last week everyone was throwing the gfs under the bus and now saying the Euro trended to it. It's more complicated than that but in a sense forecasters make it look like they move at the whim of guidance Link to comment Share on other sites More sharing options...
