1" official at BWI
-
You were in the same subsidence area that I was and east to Baltimore. Areas just to our north (Damascus to Cockeysville area) are mostly 4"+. Mostly bad luck. Probably "should have been" 3"+ for us.
-
0.3" at DCA. Woof
-
Neighbor's PWS recorded 0.18", which is probably low. I'd guess more like your total? I doubt I got over 0.3" liquid as guidance suggested I would because of that lull overnight. Probably 8:1-ish ratio eta...yup, BWI had 0.26"

My December average since 2009 is 2.8" (probably not perfect since I didn't record each event from 2009-2012, but used BWI for those years outside 12/17/09). Up to 3.4" now for this month. Tied for 3rd highest December total.

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
