With predictions of a snowfall of up to 30 inches this week, it’s interesting to note that the Office of the New Jersey State Climatologist at Rutgers pegs the annual average mean precipitation at 45.30 inches. That rate has been climbing since 1971, with the mean precipitation rate between 1971 and 2000 being 47.20 inches. Since 2000, the rate has been 46.94 inches.
Snowfall and precipitation are not equivalent; precipitation is measured as melted snow. The largest precipitation on record prior to 1971 was 45.4 inches in 1904/1905.
