* Average as calculated for the period 1993-2018. This may be contrasted with "normal" or average seasonal precipitation, typically caculated by the National Weather Service from the 30-year period 1980-2010. Although there is no official normal yet calculated for this station, due to data available only since 1993, for our purposes here, we calculate an unofficial normal of 19.66 inches, based upon the average for data from 1993 through 2010.
(1) Because data was missing for 11 months of this season, the final seasonal number cannot reflect an accurate total.

(3) Because data was missing for 5 months of this season, the final seasonal number cannot reflect an accurate total.
