PDIII Posted March 3, 2013 Share Posted March 3, 2013 DCA @ hr 63 when the light stuff arrives. Rain. namdca63.JPG DCA @ 69 when the deform band arrives. Snow. namdca69.JPG Is the diagonal line that extends upward at a 45 degree angle from 0 degrees Celsius the measurement of zero degrees celcius as you move upward through the column?

Bob Chill Posted March 3, 2013 Share Posted March 3, 2013 Last post I'll make about the nam but from hr 69-75 it's just an all out pummeling in DCA. All snow and .6+. Surface hovering between 32-34.

Doplerdurite77 Posted March 3, 2013 Share Posted March 3, 2013 Clown map looks like the kind of accumulations Wes spoke of back in either 58 or 62 when he took measurement in Annandale. Brick wall Wes please correct me if I'm wrong Link to comment Share on other sites More sharing options...
Bob Chill Posted March 3, 2013 Share Posted March 3, 2013 Is the diagonal line that extends upward at a 45 degree angle from 0 degrees Celsius the measurement of zero degrees celcius as you move upward through the column? Yes, and you can see in that sounding that the only thing above freezing (and not by much) is the surface. It's interesting that the 6z gfs and nam both came in cooler at the surface. Especially when it matters. This is a very very important trend at this point. Link to comment Share on other sites More sharing options...

WinWxLuvr gets absolutely destroyed beyond recognition. That sums up the NAM, DCA rised to around 34 during the day with S+. west of DC probably stays lower with S+ according to the NAM. now we wait for the big league models to come in.

clskinsfan Posted March 3, 2013 Share Posted March 3, 2013 NAM puts the low off of OC. That would be perfect for those of us in DC and the burbs. But it is much further north than other guidance. Link to comment Share on other sites More sharing options...

WinWxLuvr gets absolutely destroyed beyond recognition. I understand the NAM's reputation precedes it, but the fact is the only thing different about the NAM than the other reliable models is that it moves the CCB north from southern/central VA to our back yards so in that respect, even if it's wrong it's only off in the placement of the megaband then again, haven't we all expected a north shift? just sayin' Link to comment Share on other sites More sharing options...
stormtracker Posted March 3, 2013 Author Share Posted March 3, 2013 NAM puts the low off of OC. That would be perfect for those of us in DC and the burbs. But it is much further north than other guidance. The NAM is on the northern envelope of solutions. And it's the NAM. So it's likely gonna be wrong.

Bob Chill Posted March 3, 2013 Share Posted March 3, 2013 The NAM is on the northern envelope of solutions. And it's the NAM. So it's likely gonna be wrong. Exactly. It's been north of the globals every single run. People need to keep repeating that to themselves....until 12z gfs comes north... Link to comment Share on other sites More sharing options...
needbiggerboat Posted March 3, 2013 Share Posted March 3, 2013 Exactly. It's been north of the globals every single run. People need to keep repeating that to themselves....until 12z gfs comes north... It's out to h9 right now, so one more piece of the 12z puzzle will be placed on the table....You gotta think the QPF will be less than the NAM, which it usually is...Although there was a trend of increasing QPF on the GFS ensembles, so it will be interesting to see what the American models in total have to say before today's 12z euro Link to comment Share on other sites More sharing options...
mitchnick Posted March 3, 2013 Share Posted March 3, 2013 Exactly. It's been north of the globals every single run. People need to keep repeating that to themselves....until 12z gfs comes north... but all the globals have been creeping north the past few days I guess the question then is, will the NAM lead the way? let's hope Link to comment Share on other sites More sharing options...
Bob Chill Posted March 3, 2013 Share Posted March 3, 2013 but all the globals been creeping north the past few days I guess the question then is, will the NAM lead the way? let's hope I think the n creep is more a function of strength of the low and the big bad band spinning out of it vs actual track. This thing is moving kinda slow. It think that helps with not having it too compact. Link to comment Share on other sites More sharing options...
Wonderdog Posted March 3, 2013 Share Posted March 3, 2013 Is not the NAM better known for overdoing precip amounts as opposed to placement of the storm? Link to comment Share on other sites More sharing options...

mitchnick Posted March 3, 2013 Share Posted March 3, 2013 I'd venture to guess that the QPF on the gfs will be about half + lower than the NAM. Euro and GFS have both been in the 2"+ qpf range for the precip bulls eye areas so unless NAM starts showing 3"+ qpf at some point, 2"+/- doesn't seem to be outrageous Link to comment Share on other sites More sharing options...
