† 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 recorded from July 25, 2023 through Jan. 17, 2024 due to weather-monitoring equipment that had to be replaced as a result of vandalism.
