Did you have any graupel? I woke up to that hitting my window at 4am as it finally started to crank. Did not expect that. I think guidance yesterday did pretty dang well for areas north of I70, but subsidence between bands and accordingly warmer temps shot us in the foot farther south.

2” exact

Got beautiful dendrites, this will pile up well, just a question how much longer it lasts.
-
Same for Columbia. Between about 2-4am we were between bands. It’s been coming down well since, but we missed out on probably at least 1” because of that lull.
-
Lightning!
-
My temp also dropped back real quick. Wind picking up also
-
You’re right under that band. Getting good flakes?
-
Temp has actually increased about a degree in the last hour
-
Tiny snowflakes.
-
Current wet bulb temperature is 32.4
-
KIAD sounding. Freezing level just below 900mb. Biggest difference I see from the 18z 3k NAM prediction of the 0z sounding is the dews are lower. Boundary layer temps maybe a smidge colder as well.

Tomer doesn’t weeniecast. That’s impressive.
-
Harford and Cecil probably deserved warnings…
-
High of 41 and just starting to tick back down
-
Looks like the Canadian mesos
-
I’m going to be insufferable if I’m furloughed and we get a Nina torch February
-
Is it even a snow event if you don’t get NAM’d 12 hours before start?
-
I am
-
NBM looks good to me

Hello beautiful
-
CWG bumped up a little

Here's the 3k NAM sounding right as precip is about to start in DC. Above freezing part of the column is *extremely* shallow. Like 975mb or lower? And even that part of the column has a wet bulb of 32-33. At worst, that's probably like a few minutes of sprinkles and as soon as there are any rates at all, it's snow.

Let's goooo clouds. Keep the temps as low as possible.
-
3" seems like a decent floor right now based guidance. Was thinking more 2-2.5" yesterday. 4" might be a stretch, but possible.

Nice sounding in the band as it starts cranking around 1am in @mappyland
