1.4" of snow. Small sectored plates and some rimed snow. Not the kind that piles up too much yet. Still cool with the winds to see it blow through in sheets, though the fine nature of the snow doesn't cut visibility all that much..

Expect as upper levels cool and the heavy slug gets in here, accumulations should increase their rates.

22.6 degrees.

I am 2.5 fooking miles from a WSW.

The house next to me is Loudoun County-under a warning. laugh.gif I'm under WWA.

Heard a report around Dulles towne center and Rt 7 is really slick, no VDOT trucks to be seen

The sidewalks are very slippery. The roads too, if you're out walking.

friend says its snowing in Reston VA... New patch of precip about to move in...

I don't have any snow here. Moderate sleet.

ain't no way those 4-6" totals near BWI or DCA/IAD verify

NAM has the precip shield further north

all this sleet is wasted qpf

my original 1-3" around DCA and 2-4" for Balt looks much closer to reality

I still feel pretty comfortable for 5-7" to the north, though. It does look like the bulk will be gone by 3-4am.
