Closing the books on a cool and wet October

 

October 2009 proved to be a month of cool and wet conditions across the area, slowing and stalling at times the fall harvest, interfering with yard work and end of year construction projects, hampering the fall sports season, and featuring the most cloudy days in Sioux Falls for any month since 2004.  The following tables summarize some of the climatic information for the month.
