  7 inches.

* WHERE...The District of Columbia, central and southern Maryland,
  and central and northern Virginia.

* WHEN...Until 7 AM EST Wednesday.

* IMPACTS...Travel could be very difficult. The hazardous conditions
  could impact today`s evening commute, as well as the morning
  commute on Wednesday. Roads may become impassable due to the
  combination of heavy, wet snow through tonight, followed by
  significant icing Wednesday afternoon and evening.

* ADDITIONAL DETAILS...The steadiest snow is expected late this
  afternoon and evening. Snowfall rates around 1 to 2 inches per

Significant icing Wednesday? I thought that had gone away? And I didn't think it was ever something we would call significant.

Incredible. What was the NWS forecast calling for?

Just looked outside for the first time in about 20 minutes and I see flakes here in Burke.

36/28

[Interesting Times]

5 1/4 inches on the ground near Covington Virginia at 1:15 PM measured using the Driveway Method.

It's 35, so there is probably some compacting. Snowing steadily. I'm at 1,400 feet.

[LeesburgWx]

Light snow here

[GATECH]

Some one just flipped the light snow switch on! Temp is 36.7 under mostly definitely not sunny skies

So far this season all the ice warnings have been busts.

First flakes reaching the ground here. 32/22

[H2O]

well damn.  It started snowing like instantly

[EstorilM]

Temps down 5 degrees in 1.5hr down to 30.7 - nothing accumulating yet but this has some thump potential if the show isn’t supposed to start for another ~4hr or so.

Clouds noticeably thickening in Mt. Airy.

I see rogue flurries now here too. 

[wxdude64]

Not sure if that is sleet or bright-banding from incredibly snow, but that is an interesting line on radar just north of Roanoke back to Blacksburg.

Was looking at that earlier. Scared to flirt with it but I kind of need to know..

[clskinsfan]

Picked up a little bit here now. Much better flake size.

And now we are at light snow.  Nice quick transition.

[arlwx12]

A few dozen flakes near Crystal City.

Arlington still hasn't brined my Hill of Doom- maybe they thought rain would wash it away.
