I said it with the last storm and I'll say it with this one - the mesoscale models have some value in their output of how the precipitation shield may look. We can all agree that the GFS, and later the Euro, hit the past storm correctly, but they just didn't have the resolution to nail the sharp backside. That's the value of the mesoscale models. So, if the mesoscale models are hinting that there may be some lee side of the mountains effect, I'm going to pay attention to that even if we defer to the globals on track and intensity.

Forget the snow maps for a minute, the total precip numbers are pretty well in line with each other: For a spot near DC: 12z HRRR: 0.26" 12z NAM: 0.13" 12z NAM 3k: 0.23" 12z GFS: 0.25" 12z FV3: 0.2-0.3" 12z RGEM: 0.2" 00z Euro: 0.2" 06z Euro: 0.2-0.3" Throw out the NAM for obvious reasons, and it is a 2-3" snowfall.

I literally put "freshen up the snowcover" in my notes for that event.

Going to eat a lot of snow over the next 24 hours. Temps staying up near 40 in the overnight hours prior to the front tomorrow.

HRRR has a realistic scenario where there is a relative min east of the mountains and before the low strengthens.

Same, the cars cooled fastest and had the most accumulation. Ground-level snow board was relatively low compared to elevated surfaces.

No drizzle here

If the phone batteries are dead, have to do something to pass the time.

That is fantastic.

I'm guessing there are a lot of people making friends with their fellow stuck travelers.

Low of 20.7 here despite deep snow cover. Can’t fight the inversion without wind.

8.8"

I’ve been waiting for years to have a good snowfall close enough to Christmas to see the lights in the snow. Does not disappoint.

The sunshine is a nice added bonus at the end of the day. Enough to be picturesque, but not enough to start any significant melting process.

Still shrouded in cloudcover. Can't make a determination.

Northern edge is easy to see on visible. Sorry Winchester and Frederick.

It isn't a super cold airmass, but the fresh snow really helps. I'll go with breaking the sub-22 drought. 20 or 21.

We had one make two passes early on, but nothing since maybe 9am. Worst case is that they come at night and the boulders at the end of the driveway freeze solid by tomorrow am.

Falls Church, VA 1/3/22 - 8.8"

My neighbor backed out of his driveway into the street and promptly got stuck. After shoveling himself out, did he cancel whatever outing he had? Nope, just continued on. Some people evidently have different risk tolerances.

Sorry if I missed it earlier, but the southern DC beltway is a damn mess. https://chart.maryland.gov/video/video.php?feed=3e0012c100f6004f004de33696235daa

My roof cam is delivering with some blowing snow

Final 8.8” in Falls Church. This is a lot of snow!

I'm surprised that you weren't closer to 6". Take a few more measurements.
