Radar has been a bit fascinating. Heaviest stuff keeps rolling through the west side of dc up through moco west of the fall. E-SE surface flow might be adding a touch of lift running up the fall line. I might be reaching a bit but radar obs support the theory. 

 

W of 95 should do well south of Balt

I agree with your ob..and my ob here in Essex supports it.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
1029 AM EDT TUE MAR 25 2014


.NEAR TERM /UNTIL 6 PM THIS EVENING/...
SNOW HAS OVERSPREAD MUCH OF THE CWA AS OF 10 AM THIS MORNING...WITH
ISENTROPIC LIFT FIRMLY IN PLACE. THIS IS ALL AHEAD OF A POTENT
NORTHERN STREAM TROUGH APPROACHING FROM THE WEST. MEANWHILE...A
SOUTHERN STREAM LOW WAS LOCATED OFF THE GEORGIA COAST.

THE LATTER MOVES NORTHEAST TODAY...AND EVENTUALLY THE TWO WILL
PHASE OFFSHORE CREATING A DEEP CYCLONE INTO WEDNESDAY. MUCH OF
THE DIRECT IMPACT FROM A PHASED STORM WILL BE OFF TO OUR
EAST...BUT THE LIFT ASSOCIATED WITH THE NORTHERN STREAM TROUGH
WILL BE SIGNIFICANT ENOUGH FOR SNOWFALL TODAY INTO THIS
EVENING...AND ITS POSSIBLE THE WESTERN FRINGE OF PRECIP ASSOCIATED
WITH THE DEEPENING LOW COULD BRUSH OUR EASTERN COUNTIES/BAY AREA
THIS EVENING.


MODELS ALSO INDICATE SOME BANDING POTENTIAL TODAY...PERHAPS
ALONG/PARALLELLING THE INTERSTATE 95 CORRIDOR WITH HIGHER SNOWFALL
RATES. WE ARE GOING TO HAVE TO KEEP A CLOSE EYE ON THIS AS BANDING
WOULD LEAD TO MORE SNOWFALL AND ALSO COULD LEAD TO MORE IMPACT ON
PAVED SURFACES THAT WHAT WE/VE SEEN THUS FAR /THUS FAR
ACCUMULATIONS HAVE MAINLY BEEN ON UNPAVED/GRASSY SURFACES/.

we could lull or get real light at some point, but we should really rip later...

Yeah.. Winter 13-14 is a boom one. I guess we might melt off if it lulls but woosnow.
