Base layer? On what the roads? 

In Georgetown.

Only got down to 12.4 in Great Falls. 

Mostly light sleet now in GF. A little freezing drizzle and a few mangled flakes mixed in. 

4.75” in Great Falls with some light freezing snizzle. 27 degrees. Great storm. 

Last measurement for the night — 4.25” in Great Falls. 

Up to ~3.75” in Great Falls. 

Right around 3” in Great Falls. Coming down at a pretty good rate. Georgetown Pike caved long ago.

First snow of the day in Loudoun now

We drove back from Bryce to Great Falls this afternoon. Significant increase in snow on the ground around Sterling.

And there IS the virtual learning option ((except for places with patchy communications on "good" days)).

 

Fairfax announced this fall that they won’t do virtual on snow days this year. Not sure about other districts. 

Beautiful day out at Bryce. Light snow. Very light crowds. Roads were dicey once we got off 81. 

Beautiful big flakes in Great Falls. Down to 35 from 41 at the start.

An ancient Chinese proverb says that "a journey of a thousand miles begins with a single step"

The Euro took a step today but the GFS also took a step. Which one is in the right direction??

The GEM believes it knows with its giant step!!

There is also an ancient Mid-Atlantic proverb: "a journey of a thousand miles is necessary to find snow."

Please Nobody mention the word that rhymes with Bread today.

Dread? 

Still not much wind here except for a few quick gusts. Drive the kids to swim practice and back (fortunately not cancelled). Wasn’t that bad.

Picked up the kids from the bus stop and my 5th grader was *raging* at her strings concert being cancelled this evening. So I guess some students think it's dumb to cancel activities for gusty rain.

Was pouring and windy for a bit, but it's slowed down over the past few minutes. Looks like it should be pretty interesting with in the next hour.

Our kids (and us) are of the same view as your 5th grader.  Seems silly to cancel activities and close school gyms for what is (so far) a pretty unremarkable rain and wind storm.  Perhaps it gets worse later, but after-school activities would be done by then.  

Obs: Some rain, some wind, some puddles.  51.8 degreees.

Current obs: Rain with an increasing risk of puddles.  Also a light breeze.  47.5 degrees.

I agree with everything you say here other than the "something is amiss" comment.   It is plenty cold, just not here.  While a significant portion of the US has been experiencing above average temperatures and the current snow drought has been historic, it has also been really cold in other parts of the world during this same time period.  In fact areas in Asia experienced record breaking cold last winter and this has continued in to Russia and Siberia this year.   Here is an article from our old friend @Ian

We simply need to wait for our turn and I think, based on the recent guidance, our turn is right around the corner.

 

Further to this, Scandinavia is also having its coldest winter in decades. 

28.2/24 here in the alps of NW Fairfax County.

Really? I'm not sure it got that warm in Downtown D.C. today

Looks like IAD hit 43 as well.  42 here.  Now at 40.3

a good southeast shift on the RGEM and nobody bothered to post it? smh 

Seems mainly due to an increase in QPF (which leads to more front-end snow).  Overall thermals seem largely the same as 12z.

FWIW (likely not much), 18z HRRR appears to be a little colder both aloft and at the surface than 12z.
