Yes. This is what I tried to convey in my First map...I didn't explicitly display 20", but denoted that amounts in excess of 18" are possible in select areas.
BTW, last night and today was def a net-gainer for me....the 2" of fluff hardly melted with a high of 43.9 and low dews. Will do a pre-storm depth measurement later this weekend, but must be at least 6" still.
