Lol. Bad geography on my part. Outer band near front royal is pulling east now. What am amazing and extremely localized storm

I like to use this loop to see the subsidence on the back end of storms coming through.  Sure, it's composite but that's helpful in seeing the non (or very light) precip features.  It's helpful for the back edge hallucinations that are created by the spine of the mountains to our west as well since LWX radar does not typically see over the ridge tops but KRLX and KBPX can see what's over there.

It feels like i've been watching snow fall continuously for over 24 hours

I swear when I'm inside I can see snow falling. Not snow falling outside, snow falling inside. I don't think this has happened before.

...MODERATE TO HEAVY SNOW CONTINUING THIS EVENING FOR AREAS EAST OF 
THE BLUE RIDGE MOUNTAINS TO THE CHESAPEAKE BAY...INCLUDING 
THE GREATER BALTIMORE AND WASHINGTON METROPOLITAN AREAS...

At 615 PM EST, numerous snow showers, some moderate-to-heavy, 
continue in much of the region east of the Blue Ridge Mountains to 
the Chesapeake Bay, including the greater Baltimore and Washington 
Metropolitan Areas. Visibilities in some of these snow showers are 
less than a quarter of a mile, with road conditions quickly 
deteriorating now that it is after sunset.

A Winter Storm Warning remains in effect until Midnight, with an 
additional 1 to 3 inches of snowfall expected before tapering off to 
flurries around midnight.  Temperatures will drop into the lower 20s 
overnight, so significant refreezing is likely.

Icy roads are possible as the snow melts on the roads then quickly 
refreezes.  Conditions can deteriorate rapidly in winter weather 
situations. Be prepared for snow or ice covered roads. Slow down and 
allow extra time when traveling.

Snow slowly advancing northeast and I'm getting flurries. Temp down to 29. I think the eastern shore where I am has a good chance of seeing another half inch to even an inch, but that's about it.

You have.

I am getting pummeled again out here. What an overperformer with the afternoon ULL. 2.4 inches with that gives me 7.7 for the storm and still dumping.

That's a very good thing. You'll be experiencing that for the next 9 weeks.

Light sleet finally changed over to moderate/heavy snow with some huge flakes, started about 45 minutes ago, cleared roads were covered within 15 minutes.  Best snow of the storm. Temp has fallen to 30.7F.

Route 81 is a disaster. Down to one lane after being completely cleared earlier today. The road crews must be pulling their hair out. They thought they had control of it and Ma nature said psyche.

So painfully close, but up here north of 695 it's flurries, even though I'm in the dark green.

Snow intensity really picking up in Reisterstown.  Steady snow but it's mostly needles and plates.

It went from nothing to a decent clip here about 15 min after the darker greens moved over.

Richmond closing this thing out, and it was pretty much a miss here just light snow to sleet to a lot of freezing rain, with a nice burst of heavy sleet and snow. Roads covered. Probably about an inch over last 90 minutes

Heh.  I'm inside the beltway, but I'm somehow still in the light green.  The HoCo-MoCo death band is for real.

107 pages in the obs thread for this storm and 104 in the model discussion threads.  Good ratio.
