I remember that very well and talking to you that day. You are thinking of Feb 1 15. Surprise 5-6" as the sfc low exploded east of long island during the day. the first half of the storm was all WAA at night, then some sleet and it was supposed to be over. I was at 6" then got an extra 5.5" during the day.
