This graphic really exhibits how wet October was in the eastern U.S.

Every single green dot is an official National Weather Service weather station that had their WETTEST OCTOBER ON RECORD.  The larger gray dots indicate stations with October rainfall totals in the top 5.  Nearly every station in the Midwest had October rainfall in at least the top 5 wettest Octobers.  Most of the records go back 1895-1900.

Notice the number of stations across Illinois, Iowa, Wisconsin, Kentucky & Missouri that had their wettest October on record.

Most of these stations’ October 2009 ranked in the top 10 coolest, as well.
