† 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 1994. NCEI does not provide normals for this station. Consequently, we calculated our own normals from the 27-year period of 1994-2020 (as close to NCEI's normal period), adjusting for outlier amounts of rainfall recorded in June 1997 and April 2001 and missing data for much of 2000 through 2002. Our calculated total season normal is 17.38 inches.
