you got a measurement guess? I've been doing a shoddy job and am somewhere over 3" and that's all I can really say.

It has been snowing since 7am when I got my 2.5", but the accumulation has been paltry right up until this latest band with the dendrites started. 

I'm all in on my extra 1.5" overnight from the streamer on the HRRR

Radar is really looking good in MD

2.5” on 0.21” precip.  And more importantly, up to 5” on the ground, which makes up for any compaction/melting from the last storm.

Pivotal snow depth maps looks identical to 18z for the 3km NAM, but the 10:1 maps is much less for some reason.

3km looks drier to me, but I’m staring at tiny maps on my phone

What's CSI?

Conditional symmetric instability 

https://en.m.wikipedia.org/wiki/Conditional_symmetric_instability

11.7 for my low.  DCA around 16.  IAD 8.

12/11/2023 - 0.7"

1/15-16/2024 - 4.3"

Seasonal:  5.0"

Thought this was a cool grab with the sun setting at the snow-covered ridge line

I'm sure some will disagree and say temps before don't matter, but IMO the warmish temps we had(I had) the few days prior to this storm affected accums.  If it had been 30s leading up to this then I think roads/grass would have caved sooner.  But I got to 49F before the squall front Sunday.  To me and my experience, the ground and pavement was toasty.  Not a complaint but more a observation that the snow could have been better for some if you take prior conditions before this storm into account.  

 

29F current so things will stay icy for a while.

I don’t see this as a problem, though.  We accumulated on the grass where it matters and shoveling the inch from the sidewalks was easy!

My 4.25” was on 0.42” precip, so pretty much a perfect 10:1 ratio.

4.3” and freezing rain.  26.6

If the NAMs are overly aggressive with the warm air push, could have some surprise additional snow tomorrow morning. Or just ice. 

So close

Just hit 3”.  26.4

Just measured 1.8”, 28/SN

1.9" here and 26.4.  Excellent winter day.

Have a relative in town who has been trying to fly out of DCA today... airport seems to be basically closed. After 1-2" of snow? Pretty pathetic.

Looks like they are temporarily shutting down the runways for cleaning.  Planes are back to taking off.

1.5”.  According to the HRRR it should be wrapping up here.

Huh… roads have caved. Wasn’t watching closely. Game on.

Yeah, they did here too in the last half hour or so.  (It actually is the sun angle)

I bet you end up with 12:1+ ratio when you melt later. 

That would be excellent.

Goddamn you and your logic.  Next you will tell me there was enough sun energy to power a Tesla from 11am to 2pm and now its down to powering a drone copter

Peaked at 70 w/m2 earlier and now down to 32.

Its not that.  Its the radar.  There is a hole in precip that happens from culpepper to Orange to Fredricksburg.  If you watch a loop on Radarscope you can see how it just takes forever to fill in

The 3km NAM from 12z gives us 3+ inches of snow.  Through 4pm it had 0.01” qpf.  This is all just bonus scenery snow.

Impressed at the chill.  25.0 and only very slowly rising.

The number of kids sledding behind my house shows just how desperate this whole region is.

0.5” on 0.04” precip.  Ratios!

Got up to 44 here and quickly down to 35.  Started as snow.

Yeah, fell quickly to 40 and the flurries started.

47 and sun here. Enjoy the snow!!

Yeah, the temp has spiked here to 46.9.  It is nice out.

Monday and Tuesday.  Snow on snow, baby.
