Presented above is a graph of Huntsville Precipitation which was compiled by Dr. Bill Crosson, covering the years 1907-2006. Of note are the gaps in data around the Great Depression and just after World War II. The NWS's yearly climatological average rainfall is taken from the period of 1970-2000, but look at the variability in the average. Any 30-year period would give a significant difference in climatological value, up to about 10 inches.
