I flipped just after midnight...maybe 1am. I remember jumping on the NOAA weather radio and hearing that ORH already had 1' when I had just flipped.
Forecast began at 4-8" for me and kept going up. I think it ended up at 8-16", which was still a bit low. Ended up with 18". I had never seen snow like that to that point in my life, having grown up in the 80s.
The most remarkable transition that I ever saw is also my first meteorological memory...the March '84 storm. I recall that the changeover was so distinct that I could see it sweep across the neighborhood looking out the window.
