packfan98 Posted March 5, 2013 Share Posted March 5, 2013 Shenandoah Valley getting destroyed at hour 12 on the nam. Also the 0 line at 850 keeps sneaking a little more to the east. Link to comment Share on other sites More sharing options...
wxmeddler Posted March 5, 2013 Share Posted March 5, 2013 From what I understand it is. The map is automatically drawn but the forecasts that make the map are not. It's a good tool to tell what Sterling is thinking. Link to comment Share on other sites More sharing options...

Dr No Posted March 5, 2013 Share Posted March 5, 2013 The snow grid will change every hour- which is what I hate about it. The forecast is the best they can do now with the information at hand. No complaints. I'm still in the 10-14 range. Link to comment Share on other sites More sharing options...
psuhoffman Posted March 5, 2013 Share Posted March 5, 2013 Thanks, well, that is fairly healthy with some ratios I guess. Euro gets there a little differently then GFS, its a little less qpf with the initial surge late tonight, but then keeps precip going better tomorrow then the GFS. In the end it ends up with identical qpf but in a different way. Lets hope the GFS is right with round one, and the euro is right with round 2, and then we might verify close to 10". I know its a wishcast. Link to comment Share on other sites More sharing options...
MN Transplant Posted March 5, 2013 Share Posted March 5, 2013 NAM is virtually identical with the freezing line at 975mb through 20hrs, which is a very good thing for DC and west. Link to comment Share on other sites More sharing options...

blueapple Posted March 5, 2013 Share Posted March 5, 2013 Really looking like while DC will get less than N&W (obviously), the big drop off won't happen until you get into PG county and points S&E. Seems to be cooler from 950mb the surface. Link to comment Share on other sites More sharing options...
