TUweathermanDD Posted January 21, 2013 Share Posted January 21, 2013 Just south of 12z, not bad. Nice snow, doubt any rain. Colder at 850. Link to comment Share on other sites More sharing options...

TUweathermanDD Posted January 21, 2013 Share Posted January 21, 2013 I like where we stand as well, verbatim that is, about 6-7" of snow, SV maps 4-8 DC and Baltimore at hr 99. Would be some snow and sleet, better than 18z, and juiced, I agree with matt. All frozen event for sure, sfc temps are colder. Link to comment Share on other sites More sharing options...

usedtobe Posted January 21, 2013 Share Posted January 21, 2013 eyeballing 0.75-0.85 from DCA - BWI Both it and the Euro would be winter storm warning criteria storms across the area for different reasons if they were correct. It did trend a little colder and wetter. Link to comment Share on other sites More sharing options...
WinterWxLuvr Posted January 21, 2013 Share Posted January 21, 2013 actually, it didn't. It was the 1st model to forecast the watch criteria storm while the euro had zilch. Later, it jumped south while the Eruo still had little. Only in the last 12 hours did it win when the euro somehow decided to go wet. H20 was being sarcastic. I was just joining in. I know it did awful. Link to comment Share on other sites More sharing options...
nflwxman Posted January 21, 2013 Share Posted January 21, 2013 Might be too early to discuss dry slotting, but it looks like the GFS and CMC both show a pronounced one here in the VA Piedmont. Hopefully that verifies further south. Link to comment Share on other sites More sharing options...
mitchnick Posted January 21, 2013 Share Posted January 21, 2013 at BWI 18z GFS, .38" falls through 1pm with surface at -3.5 and 850 at -5.3 but thickness is at 541 so there's a warming layer likely above 850 at the end of the next 6 hours, another .38" has fallen, surface at -.2 and 850 at +.4 with thickness of 540 better than 12Z and probably 3-4" before taint of sleet hits even less zr this run I would think too Link to comment Share on other sites More sharing options...
usedtobe Posted January 21, 2013 Share Posted January 21, 2013 it is like 23-26 most of the storm I think...need soundings....DCA goes to like 34 well after the precip ends and then drops again I think the precip is over by the time the temps get above freezing. I'd be a little conservative with the snow totals compared to the 850 temps as there will be a warmer layer above 850. Link to comment Share on other sites More sharing options...

Amped Posted January 21, 2013 Share Posted January 21, 2013 After this the pattern gets real ****ty. If it doesn't work out, there's a decent chance of my winter forecast of 1.8"-2.2" busting high. Link to comment Share on other sites More sharing options...

Heisy Posted January 21, 2013 Share Posted January 21, 2013 After this the pattern gets real ****ty. If it doesn't work out, there's a decent chance of my winter forecast of 1.8"-2.2" busting high. With the MJO entering phase 8 it may just be a temp. relaxation. Wouldn't be too worried yet. Link to comment Share on other sites More sharing options...
