stormtracker Posted December 5, 2011 Share Posted December 5, 2011 im pretty sure these threads are on loops we replay every time there is a storm This 18z GFS run is the least important run of our lives. Link to comment Share on other sites More sharing options...
WVclimo Posted December 5, 2011 Share Posted December 5, 2011 and I'm in San Francisco until Friday. Yeah, I read that in the Science forum. If we get that much snow, it'll be waiting for you when you return. Link to comment Share on other sites More sharing options...

Ji Posted December 5, 2011 Author Share Posted December 5, 2011 This 18z GFS run is the least important run of our lives. i hate when people say the 00z gfs will be telling....actually it wont be...non on monday 54 hours before the event Link to comment Share on other sites More sharing options...
Ji Posted December 5, 2011 Author Share Posted December 5, 2011 don't go off script!1!! your profile says 60 degrees. Way to warm for snow..plus hot roads...terrible sun angle....bad pattern...hostile per ORH...not happening Link to comment Share on other sites More sharing options...
Ian Posted December 5, 2011 Share Posted December 5, 2011 i hate when people say the 00z gfs will be telling....actually it wont be...non on monday 54 hours before the event cliches are more fun than actual analysis most of the time. you think the 2.5" qpf the nam shows is legit? or 18z throw it out?

usedtobe Posted December 5, 2011 Share Posted December 5, 2011 and I'm in San Francisco until Friday. If you were JI, you'd hop a flight home ASAP and then complain about the 5 or 6 inches you got. Actually, I'm not saying MRB will get that much but I do think it will snow there with a good cahnce of seeing some accumulation. Link to comment Share on other sites More sharing options...

Ji Posted December 5, 2011 Author Share Posted December 5, 2011 i hope Wes is really down on January.. might mean we get a hecs Wes should do more Washington Post articles on why the pattern is a nightmare for snowlovers 4 days before a potent december snowstorm comes in Link to comment Share on other sites More sharing options...
CoastalWx Posted December 5, 2011 Share Posted December 5, 2011 your profile says 60 degrees. Way to warm for snow..plus hot roads...terrible sun angle....bad pattern...hostile per ORH...not happening The overall pattern kind of is. Doesn't mean you can't sneak a storm like this in.

Ellinwood Posted December 5, 2011 Share Posted December 5, 2011 Think 10/29 redux, only the temps and QPF line up a bit better for the changeover on the back-end: The upper-level vort. max is potent enough to create an area of strong dynamics along the back edge of the system, which will pull cooler air down to the surface and make it cool enough within the boundary layer for some accumulation as the coastal low forms and tracks northeastward. Some banding will allow for locally higher totals along the axis that has the greatest snowfall through the WV/VA mountains, south-central and eastern PA and northern NJ. I took the 12z Euro Op. solution and shifted the low center northwestward to account for for some model biases, which actually lines up fairly well with the 18z NAM after that adjustment. I believe the 12z and now 18z GFS solutions are too suppressed with this system given how strong the vort. max is. The snowfall totals could go up as the storm's track and QPF amounts get honed in on the models. Link to comment Share on other sites More sharing options...

Not likely, it is just that you can post whatever nonsense you want and not get in trouble. Myself on the other hand will get in to trouble so i censor most of the good stuff .

mitchnick Posted December 5, 2011 Share Posted December 5, 2011 I think GFS is more of the solution we want here. yeah, about a .25" more qpf than 12Z, but I'll reserve final judgment after I look at the soundings Link to comment Share on other sites More sharing options...

TUweathermanDD Posted December 5, 2011 Share Posted December 5, 2011 yeah, about a .25" more qpf than 12Z, but I'll reserve final judgment after I look at the soundings A blend of the NAM/Euro/GFS would be perfect imho, a bit more namish form of the gfs I'd really like.

Looks pretty good, like mitch said I guess you're thinking a bit north, I feel a blend of them is likely. Bmore on border of 1-2/2-4, pretty cool. Nice forecast and good reasoning.

usedtobe Posted December 5, 2011 Share Posted December 5, 2011 There are still problems with the boundary layer on the GFS, look at the 09Z zero line, it's pretty far west. That's going to be the big issue. It's sad that we essentially have the same issue as in late October. Blame the pattern. Link to comment Share on other sites More sharing options...
Ellinwood Posted December 5, 2011 Share Posted December 5, 2011 for where we are now hard not to agree. i've liked the idea of snow since early y-day at least (not sure i was really paying attention prior) in pretty much the same general area. Potential's definitely been there, but it was too borderline looking up until yesterday. Glad to see it (apparently) pan out. those numbers will work out to the north of DCA/BWI, but only if the heavy precip shield expands that far seems like only the NAM shows anything close to allowing that to happen (at least at this time) so I'm guessing you are figuring on a north trend Looks pretty good, like mitch said I guess you're thinking a bit north, I feel a blend of them is likely. Bmore on border of 1-2/2-4, pretty cool. Nice forecast and good reasoning. I think the NAM track is a fairly good call at this point (the surface low, not necessarily the QPF). Euro's close and should trend NW a bit as we get closer. GFS track is silly. I'm worried I might have to shift/expand the axis more to the north in PA/NJ, but we'll see what happens.

Blame the pattern. it really is pretty pathetic both 10/29 and this one have been driven by the strong upper level patterns vs. baroclinic boundary (if I'm saying that correctly, but you know what I mean) Link to comment Share on other sites More sharing options...

Heck I didn;t even notice the GFS track and assumed it was OK, I'm sure more suppressed than the other models. Link to comment Share on other sites More sharing options...

In October it was climo, now it's the pattern. Still, it's something to watch and I get to do another article tomorrow. Life is good. Link to comment Share on other sites More sharing options...
