DCA was 33 at 3pm FWIW 

same temp in downtown. Still waiting for the turf field to cave but my small flimsy deck is accumulating.

[Bob Chill]

Hmmm... back to all snow... didn't see that coming. Column isnt as cooked as i thought. Maybe the heavy rates in a few hours are sleet and not zr. Or maybe all snow and I get a foot... that would be bad actually... Ji would want to move here 

[Fozz]

Grass, mulch, roofs, and most non-paved surfaces are starting to cave.

Basically a dusting now.

29.1/26.0 with light snow falling here in 21057

Changing to sleet now just east of Charlottesville

You can pretty much tell based on radar orientation that the line between steadier heavier snow and lighter intermittent snows is gonna set up somewhere right along the fall line. Which is generally what models peg too. I just hope I get into that steadier heavier line. My bar is 3”. I think I could get to 4 or 5 though

About 6” here in Augusta County with moderate snow and 29°.  I went on a 4 wheeler Jebride

As soon as those yellow hit everything is going to cave.

Snowing in the lowlands!

[jwLwx]

Light snow in HdG. Starting to stick to parked cars and elevated surfaces. 

[aldie 22]

Pretty decent rates...interesting note is rooftops took longer to cave but are going down fast now. I'm sure roads are next

[IronTy]

Full cavage here. Having a daily smoke on the front porch.

...RAPIDLY DETERIORATING CONDITIONS FOR THE EVENING COMMUTE...

Moderate to heavy snow will overspread the area by 5 PM and
continue through this evening. Snowfall rates around 1 to 2 inches
per hour are expected. The heavy snow will combine with falling
temperatures and rapidly stick on all surfaces during the evening
commute. If you are travelling, drive slowly and leave plenty of
distance between you and the vehicle in front of you. Be prepared
for snow covered roads.

It's decreasing every run

[ers-wxman1]

Soundings are impressive…saturated in the -10 to -20 layer indicating strong forcing and lift in the dendritic snow growth region. Expect efficient rates and fast caving of roads after sunset for most areas. Wouldn’t be surprised to see that 6-8” line coming north a jog. Areas south of town esp Warrenton, Gainesville east may hit 8-12 in a narrow band if sleet line doesn’t push north. 

[Wetbulbs88]

Tough to see that firehose waste so much QPF literally just south of us. It's edging north but still not quite here. Push baby, push!

[ThePhotoGuy]

Alternating between flurries and light snow.

33 degrees

Pasadena

[colonelaureliano1]

Flurry machine broken right now at BWI but temp is down to 36 from 38 and radar looks to be filling back in soon with some real snow.
