We're getting noticeably bigger aggregates now with this band of ~30-dBZ reflectivity moving through MoCo.

Yeah, unless something suddenly changes, you can already see the pivot hitting a wall and just slightly edging east toward the coast.

what pivot?

[Eskimo Joe]

E0.5" Keedysville mesonet site in Washington County

E0.1" Poolesville mesonet site in Montgomery County

^both of these locations are within the western band setting up

I saw it too. It’s moving W/SW, so not sure where it will ultimately set up quite yet

I don’t wanna jinx it or anything, but it seems like it’s making its way towards my house in Western Prince William because it’s coming down hard like I haven’t seen for a while 31.  All snow all fun

HRRR has this one mayhaps

Just need it to drift east

Ripping fatties in Georgetown and absolutely nothing is sticking.

Appreciate the report. There's definitely a little band setting up right along MD 97 into Carroll County. I polled some of the DOT cameras in that area and the roads and sidewalks are starting to cave.

32.5F now - roads will prob start caving soon

IAD has escalated to fuselage topper! 

Tarmac caving now as well. My flight appears to still be leaving on time - good luck to you all tonight!

[MN Transplant]

31.6 and moderate to heavy snow.  Looking good.

HEAVIEST SNOW SINCE 2016 AND FCPS AINT CANCELLED WTFFFFFFFFFFFF

I've been working in FCPS for over 25 years. They fluctuate in their closings, but they have been burned many times by forecasts of snow that ended up as cold rain. Then parents get pissed. So they often do a delay with a re-evaluation for closing. If the NWS would give us a WARNING, they would go ahead and close. But don't worry. They will probably change it later this evening to give parents a heads-up.   

[WxUSAF]

At freezing or very close now in Columbia. Ratios should jump up nicely with these rates and flakes.

[SnowtoRain]

Winds noticeable now, rates back up, 32.2 road is white, eyeballing 2" on coldest surfaces. Snow flakes size much smaller

You calling it?  Before the low gets cranking.  Ok

He should probably not post

Switched over at 4pm. Heavy dusting now. Oldfield point. Cecil county Md. 

[snowmagnet]

Neighborhood roads caving in Fairfax. 

Apparently non-weather nerds don't use the word caving like we do. My English teacher friends have been asking me for updates all day, and they were confused when I said my deck was caving. LOL. 

[MillvilleWx]

32° in Edgewater

Moderate snow with it accumulating on everything but the roads so far, although they are starting to get slushy.

What’s your temp?  31 and holding.  Which is a good temp where I come from. 

[Chris78]

 

Moderate to heavy snow now for the past few hours. Up to 3" now. 

31 degrees

Ok so I think my area of Frederick Co is officially the snow hole with this one. At least as of now. Still a mix and all surfaces just wet.

My weather station lost connection and it says -40

Just looking at the radar and using logic. Sorry if you don't like my opinion.

Let's see what happens.

From an hour ago in Leesburg, W&OD trail getting covered quick.

[heavy_wx]

There's some indication of a dendritic growth zone signature in the polarimetric radar observations from KLWX. The ring of enhanced ZDR and KDP align roughly where the radial gradient in reflectivity is greatest, indicating rapid growth of ice crystals through vapor deposition and aggregation. These crystals tend to stick together efficiently and help produce large aggregates. Temperatures near freezing at the surface also favor larger particles.

[WVsnowlover]

Well that was fun for a little while but looks like that's about a wrap here. Have fun everyone to the east!

where are you?  sticking to everything here.

Chevy Chase right now. Kitchen being renovated in AdMo. 

Overall unimpressive rates. Maybe moderate snow. Accumulating a little on grass/trees/porch.
