Looks like Chuck posted the image above. No way I'd buy that. It would be a colossal forecasting bust from Baltimore to Philly if it was somehow right.
Definitely fighting some dry air here in Baltimore County...radar would make you think it's coming down at a good clip but it's just very light off and on powdered sugar. Seems like folks in Arlington and southern Fairfax County at the lower elevations in DC are encountering the same thing. Really hope we can moisten the column sooner rather than later.
Good to see stuff is making it to the ground quickly...even with the lighter returns. 12z RAOB from IAD only had a thin area of really dry air just below 850 mb so it shouldn't take too long to get rid of that.
For the northern folks, the LWX 1.5° base reflectivity scan seems to show some echoes increasing to your west from Cascade MD through Taneytown...looks like the northern jackpot zone is beginning to take shape.
Remember to report your first flakes using mPING app on your smart phone. The data help radar meteorologists and operational staff understand where precipitation is making it to the ground!
