3.6 in Methuen
Deepest snow depth in front of home is 20.5
Deepest snow depth in rear of home is 30.3
Two things to keep in mind with that area:
That area doesn't receive any sunshine and that area had some snow remaining after the January thaw.
I wouldn't be surprised if parts of Lawrence and Andover had 10+. When I arrived at Phillips Academy yesterday at around 3:30 it was still snowing very heavily...
