I'll cut the DC guys just a little slack. With the key here the timing and location of the shift of the low from the initial one coming across the country to the secondary off the coast, this one is a really tough call. If the air was colder, then it wouldn't make a difference. Sounds like the Sunday snow is from the initial low and the later stuff is the secondary, which will form a bit late to clobber us. That said, this is really just news because there's been so little east coast snow the past couple of years, especially in the mid-atlantic.
DC is somewhere around 750 days since the last snow of greater than one-half inch (as measured at DCA).
here's the latest NWS projection:
