JFK recorded 2.3" while LGA picked up 3.5". Those seemed to be at the two ends of the spectrum in Queens.
In the range of 16 - 18 inches. LGA officially recorded 17.3" while JFK came in at only 10.3", but I suspect that is low.
1.7"
On accuweather website on January 6th 2011, they stated that about 48 inches of snow fell.
1.7" fell on the 7th
Only 1.0" in Central Park.
It all depends on where you live. In January 2010, no snow fell in Australia.
Between 9 and 12 inches depending on which part of the city.
287 cm
50,000 inches
9.9" at Logan
I didn't see an observation from Bridgewater, but judging by surrounding areas, they got about a foot or slightly more. You can look at dozens of reports for this storm in the area at the related link (which is time-sensitive, though there probably won't be another PNS for several days to outdate it).
11.5" was reported in Natick.
