Unlike the park, they do measure and start over every 6 hours. Not only that, they report new snow every hour.
It is very unlikely to exceed their totals using a different measuring protocol (non FAA), but that's just the way it is.
I don't have a major issue with today. ISP had hours more accumulating snowfall than there was here despite being only 8 or 9 miles away as the crow flies.
I am a wee bit envious of those who didn't spend a huge chunk of the storm in a subsidence hole, or whatever that was. On the other hand, we're still digging out and the xc skiing will be great.
