As @Bob Chill predicted earlier you can see the dry slot filling in back towards culpepper and front royal.

Band over silver spring is legit, dumping dendrites.

Flake size increased notably in Takoma Park the last few minutes.

This little band over Montgomery doesn’t look amazing on radar but is accumulating efficiently.

Nice little band over Takoma Park, everything whitening up in a hurry.

32/24 with SN- instantly sticking, I love starting off a storm at or below freezing and not waiting for it to cool down.

Adding up the lower bounds of the precipitation 6 hr maps I get about 0.5 inches for DC, so it should be a good run.

Hard to tell on meteocenter maps on mobile but I think UK improved a little with the Sunday night action.

Main takeaway for me is it agrees with the placement of the CCB band Sunday afternoon/night with the NAM/ICON, just not as wet as the others. IMO a very good run.

Looks like a little more action overnight Sunday which is an improvement too, not a blockbuster but another positive run.

Not seeing the coastal kick in like the ICON or NAM, but still another good run.

GFS wetter with the overrunning through 18 hours...

It bumped the blues further north, better for most folks but not up towards Baltimore.

ICON is 0.75+ for DC with an inch around Annapolis.

With the way the banding looks I’d expect more around DC....

RGEM also with the coastal further north and better snow into Sunday night, should be improved as @Beachin noted.

ICON has banding around DC 03z Monday, should be a big hit.

ICON looking better as well....

The extra snow with the Vort pass shown on the NAMs would be superb. Really hope that happens, love me some ULL snow.

3K matches pretty well with the euro. Argues for upping DC to 6-8.

HECS on the nam

LOL 12-16 inches down in DC and still dumping at 00z Sunday

Bigtime weeinie run, probably gonna be 10-12 for DC based on the way the radar looks.

Wow! 6-8 for immediate DC metro! Maybe even better if we can get ratios to work out.

As for headlines, did upgrade the advisory to a warning for the northern Shenandoah Valley and the Washington Metropolitan area. Am concerned that east-west oriented banding may cause locally higher amounts across these areas. Frontogenetical forcing increases as the low passes by to the south late tonight into Sunday morning, and looking at the 00z nam bufkit, did notice the Eqivalent Potential Temperatures nearly neutral with height for a period between 06 and 12z along with slightly negative EPV and Frontogenetical forcing that lines up, suggesting that CSI banding is possible. Elsewhere, left the headlines from the previous forecast. Still looking at a most likely of 2-5 inches across northern Maryland, the eastern Panhandle of West Virginia and the Baltimore Metropolitan areas, with 4-7 inches elsewhere. Do want to point out that there is still uncertainty regarding the placement and location of any banding precipitation and also with the track of the low. Any slight change in either direction will have an impact on snowfall totals. Having that been said, there will be impact from snow across the entire CWA tonight into Sunday.
