Some of that is from orographic enhancement over the mts...so you'll see a bit of a decrease in the intensity but it should hold together. 

Last I checked, the Froude numbers were 1.5-2.0 so the flow perpendicular to the ridges was not blocked at all and easily cresting the tops. You have to be subcritical blocked for the mountains to rob all the moisture.

No video, just sound.

Looking down the runway at DCA, looks like vis is 1/2sm.  

Video won’t upload so here’s a screen cap.

Clarksburg MD at 12:55pm 2.0”

Looks about right. Table still had snow on it but the railing was clear  

Edited to add, I like what I am seeing upstream. @WxUSAF (I think) had it right about a second impulse coming through.

Btw, it’s columns, needles and plates falling in Clarksburg. I have a cool slo-mo video from when I warmed up the car.  You can see the occasional plate sparkling in the headlights. I’ll try to post it when I am at the airport  

File is too big so I uploaded it. Let’s see if the slo-mo is preserved

That was January 2016, just a few days before the blizzard.  I had to leave my van and seek refuge in a friends house until someone with a jeep could pick up me and my kids.  And even the jeep got into a small fender bender on the way home.  That night convinced me to get snow tires (Blizzaks) on my minivan for the winter.  

+1. Best snow tires out there. They make driving in the snow and ice a revelation.

0.5” and 14.8°F in Clarksburg as I left for the airport at 9:15am. @Ka60, you have the conn for Clarksburg measurements for the rest of the storm!

High ratios there, cool

Maybe. Colder does not always equal high ratios. When it gets too cold, columns and needles become the predominant flake type.  At onset, it’ll likely be around 10°F with around a 0°F dew point. And with a column as cold as it is with limited moisture transport, I’d guess those flake types will predominate. 

For example, last week in VT, it was snowing just on either side of 0°F with 30 dBZ returns and, for the first 6 hours of the storm, the snow ratios were 9:1. Only after 6+ hours of a southerly 70kt jetstreak above 800mb did enough moisture transport in from the south to change the flake type. It was 0°F at the surface but jumped 22°F in the snow growth zone and ratios jumped to 15:1. This little impulse is just not that dynamic. 

-1.6°F was the low for me here in Clarksburg. 

Already down to 5°F here in Clarksburg at 9:45pm.

light snow foggy bottom even though radar not showing much

Same here just west of the White House.

0.3" in 20 minutes was my total in Clarksburg.  Temp went from 27F to 17F in 10 minutes.

I have GOT to experience lake effect some day.  That's definitely on the bucket list.

+1.  I've experienced it twice this winter in upstate NY a couple of times I've driven instead of flying to VT.  First time(s) for me.  They are remarkable and worth the trip.

Squall has hit Clarksburg

My snow is so wet and dense that my electric snowblower quickly choked on it.  Had to just use the shovel.

They didn't do our streets and it's like 1-2" of slush.  Going to be a sheet of ice tomorrow morning.

Mine too. Pretty dense. I’ll try to get a water content later. 

2.4” was the total for me here in Clarksburg. 

Just got home in Clarksburg. 1.9” otg leading up to the next incoming burst of 35 bBZ returns.

 270 is starting to cave at exit 9 in Rockville.

The rain snow line is in Georgetown in DC

Light rain in DC.  I don't care what the temp is because it raining instead of snowing.

Heading out for Clarksburg in an hour.  Where they know how to do precip in January.  :^P

It was a good day. 16.9” snowfall total in Charlotte, VT. I can’t say I’ve ever seen 40 dBZ returns with subzero temps (-6°F) before. It was very cool to see the raging SSW WAA above 800mb and NNE cold air draining down the Champlain Valley at 925mb.  Very cool storm.

What town in VT is this?

Charlotte, VT. 13 miles south of Burlington in the Champlain Valley.  3 miles east of Lake Champlain.

You got snow tires?

Yup. Bridgestone Blizzaks. The best there is. You can’t get around anywhere in interior New England during the winter without dedicated snow tires. 

I have some pretty spectacular videos too. I’ll get them uploaded and linked here later today. Going back out to shovel!!!
