Agree, I would take 4 - 5 inches in December and run!  The question will be will the inevitable jog to the north occur early in the models or late, it always seems to.  We get the congrats RIC, RIC in the  bullseye, jackpot RIC, then it shifts and well, the rich get richer.  Hoping for a solution that works for everybody.  Let's see today if GFS starts creeping toward Euro solution.

Just watching the models this feels very December 2009 to me. We will ride the line for sure, but, as of this moment, it looks like we could be on the "right" side of it, ironically yes the left side of the S/R split in the RVA metro area. I remember 2009 was a classic too close to call storm up until the very last moment. And when it was hammering snow in Richmond that Friday night it was raining in the Tri-Cities. Accumulation map shows an incredible cut off. My house in west end of Richmond got a foot. Folks in Hopewell got maybe 3-4 inches on backside. Feels like a similar deal unfolding, with perhaps a little more cushion. I'd take that in a heartbeat of course

For expectation management going into this weekend, here the official December snowfall events at RIC going back to 1950. Amounts are generally less than 6 inches (6"+ in bold). The two earliest snowstorms delivering 6 inches or more occurred on November 6-7, 1953 (7.3") and December 11, 1958 (6.7"). December events exceeding 10" have only occurred twice since Richmond's snowfall observations began in 1897. Those were December 12-14, 1917 (10.4") and December 22-23, 1908 (17.2").

So, climatologically speaking, big events are not as likely to happen in December. If a decent event doesn't pan out this weekend, hopefully, there will be other opportunities during more favorable times of the winter.

A look at the overnight models coming in from Tuesday night, (00Z Wed.), shows the following for Richmond, VA today on Wednesday, December 5, for snowfall today:

00Z Nam; 10:1 ratio -->>  0.3" snowfall

00Z Nam; Kuchera -->>0.1" snowfall

00Z H-Rap, 10:1 ratio -->>  0.4" snowfall

00Z H-Rap, Kuchera -->>  0.2" snowfall

00Z Gfs 10:1 ratio -->>  0.3" snowfall

00Z Gfs Kuchera -->>  0.0" snowfall

 

So a BLEND average of all projected amounts above, yields  0.22" of new snowfall for today.  This is nearly 1/4" of snowfall.  This amount is sufficient to cover tops of cars and blades of grass; also tops of fences & fence posts.    Timing looks to be from early morning to early afternoon, for Richmond, VA area, spreading in from West to East.  

 

Forecast Skew-T soundings show that temperatures will be ABOVE freezing below 1,100 ft early Wed. morning, but BELOW FREEZING temperatures will reside from 1,100 ft on upward through the rest of the tropospheric depth.  

 

Thicknesses are within range to support all snow, with 1000-500 mb thickness to be 526 dm; well below the needed 540 dm line, on the 1000-500 mb thickness. Lower layer thickness between 1000mb - 850 mb also support columns for snow, with 1286 progged, below the benchmark snow criterion of 1300 m.

How many times have we had snow in  Richmond (say over 6 inches) and less then an inch in DC?

I would assume it has not happened much.. anybody know?

 

Last winter had multiple events when RIC was heavier than DCA and IAD.  Final totals for the season:

 

BWI: 15.4"

DCA: 7.8"

IAD: 11.9"

RIC: 12.4"

 

Our primary events for Henrico County were on 12/8/17, 1/4/18, 1/17/18, 3/12/18, and 3/21/18

Right .....but I asking for larger events that ended up being more then 5 inches and DC is less then an inch at the same time....
