3.63" since 330 Monday morning.  Looks like some minor flooding predicted on the Potomac.  Its been a few years since we have had a good flush.

12/11:  .5"

1/6:  1.5"

1/15-16:  3.25

1/19: 3.25"

2/13: 3"

2/17: 2.25"

Season Total:  13.75"

1.5" on the board.  Smaller flake size now but that band was sweet.  Need more of that!

Mod snow 32/29

under yellows with heavy snow and visibility under 1/4 mile.

Same here.  Impressive rates..

Highs Fri upper 30s low 40s across the region with a dry airmass in place 8-12hrs before snow moves in.  It's not a total crap airmass to work with.  Just need to juice it up!

EPS with a west track/miller B look for the 23rd timeframe. Not the best look for now but a big jump south from 00z.  

12/11:  .5"

1/6:  1.5"

1/15-16:  3.25

1/19: 3.25"

2/13: 3"

Season Total:  11.5"

The lighter returns behind that band are a steady mod/hvy snow.  Just under 2"  32.1/31

Impressive to see the dynamics play out.  Temp crash started at 4am and the flip to snow was an hour later.  Big pillows falling now. 32.3/30

Rippage here right now.  Temp is crashing a bit better than I expected.  33.2/31

A slushy coating but this should paste everything here shortly.

2" bar IMBY.  As long as that comes in a two hour pasting I'll consider this a major victory. The local ridges will be picturesque tomorrow as the storm is departing.

This thing is looking pretty damn dynamic. 

These rates right before the flip.  Going to be key to a fun morning of obs.

12Z HRRR even better than the NAM's. It is a thorough pummeling out this way:

Yea, a 985 at the mouth of the Bay should be able to put on a show out this way.  

It is a lose lose situation.  We need enough confluence for cold but that leads to suppression with a beast ridge flexing. Less confluence leads to the ridging pushing SE and suppressing....or too warm if precipitation does come north.  I don't see a middle ground for us to win.

This has been showing up on guidance for awhile now. Probably our first legit shot at something, despite marginal cold air availability.

How dare you show a snow mean! lol  Yeah, you and others have hit on this timeframe for a few days.

Not a bad look for an ens mean 9-10D out.  Would be great to score something during the "torch" before heading into primetime. 

3.2" matches exactly the last storm's total.  Unless a streamer adds a bit more I think that's about it.  Light snow 30/27  5.5" snow pack.

The HRRR runs all morning have been parking this narrow band over my yard this afternoon and sitting it there snowing itself out for a couple of hours.

Would be great if it’s on to something and my area can play catchup on accumulations. 

Oddly consistent this morning with such a narrow band. 3k NAM shows the same thing.

The Keedysville site is at the Western Maryland Regional Education Center Farm that UMD has off 18330 Keedysville Rd, Keedysville, MD 21756

Gotcha.  A bit west of town.  I follow their reporting on Weatherlink as one of my local stations.

Keedysville mesonet site in Washington County is having some waffling on the snow depth sensor. Must be some big flakes falling out there.

Im 2mi SE of the town of keedysville and can confirm there was a period of light snow with larger flakes.  Back to finer snow now,  I measure just over 2" about 45 minutes ago.  But, I was living on the extreme NW side of the heavier stuff this morning.  Where exactly is the site location? Out of curiosity...

Light snow falling but nice fluffy flakes.  Just measured 2.1"  

Mod snow...eyeballing .5"+  25/22

Interesting that band from roughly HGR-DC is still there on the NAM/HRRR.  

Currently 10 after a high of 25 today.  Looks like tuesday will be the first opportunity to get above freezing.

Please no. Feels like that would make a big dog more difficult...

It would be more challenging but it would certainly feel like winter.  Amped systems cut and we hope for timing something...sort of what we just went through.  Others more knowledgeable could probably parse potential ground truth outcomes better than I can.
