Great write-up! Point #3 is what I will be watching for. During the 2016 blizzard, immediate DC dry slotted for much of the day before the major CCB rolled through, and it was epic! However, I watched from my Pentagon City Apartment while Loudoun West was getting pummeled under it for hours. It is why I "only" got 18" while my current home here in leesburg ended up with 35-38". High ratio heavy snow is where it's at and I hope this storm can pull some surprises in that regard.
