3" on the button, so 1.8" in the last hour!  Sleet now.  Grass is nearly all covered, so it's better than most of our storms...

Let's see what happens now.

1.2".  0.9" in the last hour.  Biggest December snowfall since 2017!  

Coming down well right now.  Feeling good about 2" and 3" seems quite possible?

KOKV reporting Snow with vis at 0.25. Not sure what constitutes heavy but ok

That's it!  1/4mi

Embiggening snow flakes under those oranges now

Taking a @Jebman Jebwalk as soon as this stupid virtual meeting ends

Some snow on Rt 108 behind me, which is a snow emergency route and was brined yesterday.

Temp has backed off from 30.6 to current 29.3 after morning low of 27.4. Guesstimating/eyeballing between 1/2” - 3/4”

Those bright radar returns about to reach us...interested to see what that offers.

1” on the board.  Nice job by the HRRR.

Nice!  

Eyeball visibility near the border of -SN and SN (5/8mi).  

Paved surfaces starting to cave

First official spotter report: 0.3"

On the board for winter 2020-2021!

Anybody got a radar shot of that sleet line again. Is that something I can do on RadarScope?

I swear it has to be under 20F for my driveway to get snow covered.

Flakes growing in size a bit. Radar looks great to the south. Looks like heavy bands of snow developing and heading this way, unless that's all sleet.

CC mix line has been pretty stationary for a little while thankfully.  I'd like our rates to pick up soon so we can max out the snow time.  

Dusting on all unpaved surfaces.

Imagine we had some semblance of blocking in place to keep that high anchored in

We do have some semblance of blocking.  A track up the Bay would be rain to Binghamton if there wasn't that high pressure/confluence/blocking.  It's not 100% perfect, but the best we've had in ~22 months.

DCA reporting -SN. College Parks latest METAR w/ 5SM visiblity would imply -SN as well but that station may not have a precip identification sensor.

First T of the winter for DCA?

-SN enough now in Columbia that normal people would notice

Snow heavier damn it!

I haven't been this anxious for snow to starting accumulating since the last time snow accumulated.

I told the kids snow starting around 10am. I’m going to get pestered every minute after 10am if it’s not...

F-CKING NAILED IT

And they've still been pestering me all morning

yes, i know that feeling well. especially when its coming from the SW. I'm one of the last in the forum to see flakes (harford county folks worse off than me)

Ok, snowing now.  Instant patio table accumulation!

Any time now snow

Reminder to include your location with Obs!

Not sure if everyone is just trolling but radar seems pretty good to me relative to what the meso models had at this time.
