Let's please put to bed this crap that you need a 36 hr event to get big totals. This event is a perfect illustration...this SLOW mover has consisted of 10-12 of all hell breaking loose, and another 12 hrs of flurries. This is not a complaint whatsoever...loved the event, but big totals are achieved via several hours of intense dynamics, not 48 hours of impact.
Okay, if you have a depth of 18" right now, then you had 20.5". That makes sense from my Wilmington measurements, as the depth when I left was 17" at 1am.
I have a current depth of 14" in Methuen, and had a 16.5" snowfall.
15" depth in Methuen....15.5" snowfall. 2" less than Wilmington, and its apparent that it never got above 29 here....all drifted powder. There was zero drifting in Wilmington.
