SomeguyfromTakomaPark Posted February 3, 2014 Share Posted February 3, 2014 NAM per WxBell is a slap in DC's face. Is that the right map? Link to comment Share on other sites More sharing options...
mitchnick Posted February 3, 2014 Share Posted February 3, 2014 Is that the right map? based on the time stamps, it is, but that is plain wrong looking at the ncep maps Link to comment Share on other sites More sharing options...
lsukev Posted February 3, 2014 Share Posted February 3, 2014 Looks like it to me Link to comment Share on other sites More sharing options...
lsukev Posted February 3, 2014 Share Posted February 3, 2014 It has to be based strictly off the 850mb temps... and of course 10:1 ratios. Link to comment Share on other sites More sharing options...

Ian Posted February 3, 2014 Share Posted February 3, 2014 Wx bell is great but the snowmaps are terrible. They should just stop serving them up. Link to comment Share on other sites More sharing options...
nj2va Posted February 3, 2014 Share Posted February 3, 2014 based on the time stamps, it is, but that is plain wrong looking at the ncep maps Its strange....DC 850s are below 0 at 7a per WxBell (and stay below 0). NCEP maps are warmer though. Link to comment Share on other sites More sharing options...

mitchnick Posted February 3, 2014 Share Posted February 3, 2014 according to Plymouth, every station IAD, BWI and DCA, has the warm layer at 750 even when the 850 cools Wxbell maps are carp Link to comment Share on other sites More sharing options...
Solo2 Posted February 3, 2014 Share Posted February 3, 2014 Looks the 850 retreats a bit from 12hr to 15hr... Link to comment Share on other sites More sharing options...

blizzardmeiser Posted February 3, 2014 Share Posted February 3, 2014 We suck at this stuff It's over for dc but points north should do well Link to comment Share on other sites More sharing options...
lsukev Posted February 3, 2014 Share Posted February 3, 2014 I've mentioned this before. Why do the SREF plumes suck so bad? They still have Dulles at 6" with most members above that. DCA still at 4". Link to comment Share on other sites More sharing options...
mitchnick Posted February 3, 2014 Share Posted February 3, 2014 It's over for dc but points north should do well gotta get north of BWI if NAM verifies Link to comment Share on other sites More sharing options...

nj2va Posted February 3, 2014 Share Posted February 3, 2014 Hires NAM 0z 850 line is draped over DC at 7a. I'm sure there are those warm noses elsewhere. Link to comment Share on other sites More sharing options...

WxUSAF Posted February 3, 2014 Share Posted February 3, 2014 Didn't the Euro look really good with an entirely cold sounding by 12z? Link to comment Share on other sites More sharing options...
yoda Posted February 3, 2014 Share Posted February 3, 2014 Didn't the Euro look really good with an entirely cold sounding by 12z? Pretty sure the 18z GFS looked good enough for DCA at 12z as well with a good enough sounding for wet snow as well Link to comment Share on other sites More sharing options...
Subtropics Posted February 3, 2014 Share Posted February 3, 2014 This is a nowcasting situation anyway. I am not giving up until the event begins. Link to comment Share on other sites More sharing options...
mitchnick Posted February 3, 2014 Share Posted February 3, 2014 Didn't the Euro look really good with an entirely cold sounding by 12z? yes for IAD and somewhat BWI, though surface was 33-34 Link to comment Share on other sites More sharing options...
winterymix Posted February 3, 2014 Share Posted February 3, 2014 Crushing rain. I ran the forecast soundings derived from the 0Z NAM and your area as well as my area are wire to wire snow with all layers of the column frozen from around 11Z until about 21Z.
