* Although normals are established by the National Centers For Environmental Information, based upon averages for rainfall seasons 1991 through 2020 (updated May 4, 2021), this station's data only goes back to 1993. NCEI does not provide normals for this station. Consequently, the Almanac calculated unofficial normals for this station from the 23-year period of 1993-2020 (as close to NCEI's calculation period as possible), adjusting for unusual outlier amounts and missing data. Total season normal for this station is 16.26 inches.

** No rainfall data was received at all during this month. Last update provided was on July 25, 2023.
