About .5" near Oakton, Virginia.  The roads were briefly slush covered.

Everyone talks about late March 1993 around here.  I guess that one wasn't over 20" in Baltimore, so it doesn't count.  I was living in Louisville that year, so I don't know how much we had around here.  
 

March 1993 was way bigger and covered a very large area, but for Baltimore, the snow was not as deep as 1942.  Here's a comparison for Baltimore: 1942 produced 22" of snow with 2.05" liquid content, and 1993 produced 11.5" of snow with 2.45" liquid content.

1942. 
But…there is one group here that apparently has decided it can’t snow anymore before January and now they want to toss after Feb 20 then I say “it’s getting harder” and another group wants to crucify me. Which is it. We can’t start tossing a freaking HUGE portion of our historical potential snow climo then at the same time act like everything is fine and we will somehow get the same snow results compressed into 6 weeks that we used to expect spread out over 12 weeks. 

1942 was big.  Even bigger than 1958 for the greater DC area.

I think in 1977 it went below freezing for like 37 consecutive days 

1977 was impressive because snow was on the ground at DCA for 24 consecutive days from three back-to-back snowstorms in early January that only dropped a total of 8.7" of snow. The snow didn't melt for weeks.  However, in 1961, there were 30 consecutive days of snow cover at DCA in late January and early February from six snowstorms that dropped 31.6" of snow throughout that period.  The winter of 1960-61 also had 16 consecutive days of snow cover at DCA in mid-to-late December which included a white Christmas.  What a great winter!

I'm under the green and yellow radar returns northwest of Fairfax.  Heaviest snow of the day by far.

2.75" so far today in Oakton, VA and over 6" snowpack on the deck.

The Manassas Battlefield Park did well with the morning snow bands.  There was about two inches of snow on the ground by 3:30 this afternoon.

Quick search shows no Winter Storm Warning for DC since 2019. Could be wrong.

D.C. had a winter storm warning on Jan 3, 2022.  I measured about 8" at the Tidal Basin.  It was a classic D.C. snowstorm.

The point of the articles below is that it can still snow into April, not that it will.  Pattern last week of March will have to be monitored.

From the start of snow records in the late 1880s, fairly regular April snow events continued until 1924. During that period, 2 storms were particularly noteworthy: (1) the April 3, 1915 Easter weekend storm, which left 3.5 inches in D.C., but 15-20 inches in a swath from Philadelphia to Dover, DE; and (2) the April Fool’s Storm of April 1, 1924, which dumped 5-6 inches of snow on the Nation’s Capital and 9 inches in Baltimore. The latter was D.C.’s greatest official April snowstorm and appeared to be the culmination of regular April snow events in Washington. Since then, there’s been only about one per decade.

Also of note:  On March 29, 1942 11.5 inches was measured at Reagan National. The storm produced over 2 feet of snow in parts of Maryland and northwestern Virginia. That snowstorm also ranks as Baltimore’s seventh-largest storm on record; 22 inches was measured.

As recently as April 7, 2007, it snowed about an inch in D.C., but 0.4" was the official measurement at DCA.  Here's a shot I took that day at the Capitol.

A bumper of a F-150 is not a great snowboard, but it provided the deepest snow measurement.  The average measurement was 3.2" near Oakton, Va.  That last snow burst was impressive.

2.4" near Oakton, Va.

I think it is the Hallett-Massop process that caused them.

Here's a close-up of the needle-shaped snow crystals that fell this afternoon with the sleet.

Sleet-coated road in Oakton, VA this afternoon.

Between Oakton and Chantilly, the sleet has mixed with small, needle-shaped snow crystals.  My driveway is encrusted with a thick layer of sleet.

Cool picture. 

Thanks.  I have many more.  I plan to put together a CWG post.

Great Falls was beautiful this afternoon.  They had about 1.5".  With the very cold temperatures, the snow painted the rocks.

Wow!  Are you in Centreville or further north?

Northeast of Centreville, not far from Reston.  The official zip code is Oakton but near the Herndon line.

Around 3" in western Fairfax County.

This has become one of my favorite photos of Snowmageddon. It shows the depth and density of the snow. You'll never see this kind of photo with lake-effect snow.
