There's a good reason if the Philadelphia Phanatic is looking greener than usual lately. After the summer rainfall record was broken just 1 day into August, another 2.02" this morning has pushed the Philadelphia seasonal precipitation total even further into record territory. With over 2 weeks left, the unofficial June-August rainfall total of 27.56" is barely less than 3" above the old record of 24.58" set just 2 years ago. The seasonal total to date is 245% of the climatological average for the entire 3 summer months.
