Hey! The BWI crew are people too (I've always wondered why more Baltimore folks don't post here...it seems to be either DC or snowbelt, lol) 

I prefer to lurk in the shadows, tbh

Rain/sleet mix in Forestville, a trace of sleet so far, 33/29

Dulles reported 5.1" of snow as of 444am

SUMMARY...Moderate to heavy snow now developing across parts of
   central Virginia and Maryland is expected to persist through mid to
   late morning, with rates (around or in excess of 1 inch per hour)
   likely maximizing in the 6-10 AM EST time frame.

   DISCUSSION...A broadly cyclonic 50-70+ kt 500 mb jet streak
   continues to gradually develop eastward across the northern Gulf
   Coast states, with its exit region now beginning to nose to the lee
   of the southern Appalachians, toward the southern Mid Atlantic coast
   through mid to late morning.  It appears an associated broad area of
   strong upward vertical motion will include a period of strengthening
   lower/mid-tropospheric frontogenesis across Virginia and adjacent
   portions of the Mid Atlantic.

   Across central Virginia into adjacent portions of central Maryland,
   where temperature profiles are expected to remain entirely below
   freezing, models indicate that lift may begin to become maximized
   within the favorable mixed-phase layer for dendritic ice crystal
   growth by daybreak, and continue through mid to late morning.  Aided
   by relatively high precipitable water content (up to around .70
   inches), one or more bands of heavy snow, at rates around or in
   excess of 1 inch per hour, appear possible.  Forecast soundings
   suggest that this may persist for a 3-4 hour period at any
   particular location, generally in a narrow corridor from the
   vicinity of the Blue Ridge, north of Roanoke VA, east/northeastward
   through southern portions of the Greater Washington D.C./Baltimore
   Metropolitan Area.
