I thought it was around 42 inches because growing up, that's what The Weather Almanac listed as the long term average for NYC.... This book was published in 1973 with an update in 1991 (I have both).  The last 30 year average it mentions is the 1961-1990 (the previous one was 1951-80).  What were NYC rainfall normals for 1951-1980 and 1961-1990?
 
	Was it really that much cooler prior to 1970-- look at all these hot and dry summers we had before:
 
	1944, 1948, 1949, 1953, 1955, 1966, we have some extremely long and very extreme heatwaves in there that have not been matched since.
