We are losing here because of synoptic-scale stuff, not hidden warm layers though. The 850 low is even stronger and further NW than prior runs of almost all models, which just kills us.
Fairfax County has end of the quarter teacher workdays on Thurs/Fri and an early dismissal on Wednesday. There's basically no chance my kid will be in school next week.
I have no doubt that elevation was huge in 2006. That storm is why I don't question the low amount at DCA in borderline events, though. It really is warmer down there.
One of my disappointing storms. My first chance at a big east coast storm and then it snizzles all day, snows overnight, and starts melting immediately in the morning. <9" down at my rental near the Pentagon.
The crust on top of the snow is going to be amazing by the time Tuesday rolls around. Let's reel the following weekend's storm in and get snow-on-snow.
My estimates of the precip before and after the modeled changeover in DC.

Yeah, 06z is sleet, but it isn't like we spike way too warm. Like I was talking about yesterday, the 850 low on the GFS is just more diffuse and reforms near or over us.
GFS is more of a two-parter than some of the other models. First comes through cold and all snow. Looks like the 2nd is going to be latitudinally-dependent.
