As we thought yesterday, Harford and Cecil would have verified warnings. North Baltimore and Carroll would have also and NW MoCo and NW HoCo came damn close.

Yeah that looks legit. BWI on the other hand…multiple spotter reports over 2” nearby

Brother in law in forest hill measured “a bit over 4”

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
