ravensrule Posted February 12, 2013 Share Posted February 12, 2013 I think this might be OK for DCA to BWI and NW. At some point between 42 and 48 we flip to snow and what falls afterwards is money. Certainly not a doomsday scenario and the best look in a while, I think. In a marginal setup like this it is unlikely that DCA does as well as BWI and north.

usedtobe Posted February 12, 2013 Share Posted February 12, 2013 Except in Feb '87.. it was snowing at 42 degrees before we got 12" This is not anything like that, we pretty much knew the 1987 event was going to be snow before it began. Anyway, I'm done for the night. This is one that elevation should help. Link to comment Share on other sites More sharing options...

ravensrule Posted February 12, 2013 Share Posted February 12, 2013 If we got as much snow as those clown maps, my snow climate would be like living in CT. That is great, this way you can measure 35" with the storm Wed night like Kevin. Link to comment Share on other sites More sharing options...
PhineasC Posted February 12, 2013 Share Posted February 12, 2013 Looks like the surface doesn't cool until 60 though and by then the precip is outta here. You are wrong. Link to comment Share on other sites More sharing options...

mitchnick Posted February 12, 2013 Share Posted February 12, 2013 Mitch, extrapolate the NAM right now to PD3. well, OK here's the 84 hr NAM 700mb RH http://mag.ncep.noaa.gov/Image.php?model=nam&area=namer¶m=700_rh_ht&cycle=00ℑ=nam%2F00%2Fnam_namer_084_700_rh_ht.gif here's the 90 hr GFS from 18z run http://mag.ncep.noaa.gov/Image.php?model=gfs&area=namer¶m=700_rh_ht&cycle=18ℑ=gfs%2F18%2Fgfs_namer_090_700_rh_ht.gif looks pretty similar down in OK and KS, which is where the GFS had the slp forming you asked, I performed Link to comment Share on other sites More sharing options...
SomeguyfromTakomaPark Posted February 12, 2013 Share Posted February 12, 2013 You are wrong. Really? Maybe I was looking at the older run..if so my bad! Edit: just checked again on Raleigh...lookin' at 2m temps at 54 and the 32 line is well NW of DC and then at 60 it has just passed SE of DC...am I looking at the wrong map? http://raleighwx.americanwx.com/models/nam/00znampmsl10mwinds2mtemps060.gif Link to comment Share on other sites More sharing options...

Kmlwx Posted February 12, 2013 Share Posted February 12, 2013 Ah I don't have access to soundings...well that's good news I guess. Everyone has access - they are public - just need to find a website. We've seen it snow at 38 or 39 plenty of times if it's cold aloft. Not all about one layer of the atmosphere! remember it's not just about surface - you need to factor in all the important levels (surface, 950, 850 are the biggies) Link to comment Share on other sites More sharing options...
