                     Review of Weather, Temperatures, and Precipitation for the Quad State Region.

 

                                        Weather Summary for September 2004

 

September turned out to be a record-breaking month for dry weather.  Both Evansville and Paducah set records for the driest September on record.  September was the driest month on record for Paducah since record began in 1949.  Evansville recorded 0.09 inches and Paducah only 0.02 inches.  Other locations included Cape Girardeau, Missouri with a trace of rain and Carbondale, Illinois with 0.12 inches.  Numerous other cooperative observers also recorded less than 1 inch for the month.  Average temperatures for the month were within a degree and a half of normal (68 to 72 degrees).  

 

Several cold fronts traversed the region in September (6^th-7^th, 15^th-16^th, 24^th-25^th, and 27^th-28^th).  However, high pressure over the eastern United States and major land-falling hurricanes in Florida disrupted each front’s ability to produce precipitation.  Average precipitation amounts for these events were less than one-tenth of an inch although a few nearly stationary, short-lived storms managed to produce one-half to three-quarters of an inch.

 

Of Special Note: The Atlantic Hurricane Season continued to wreak havoc on the state of Florida.  Three hurricanes made landfall this month.  Frances and Jeanne hit the southeast coast while Ivan, a category 4 storm, slammed the panhandle.

* Range of averages is taken from the range used to calculate normals: 1971-2000.    

 This gives the highest and lowest June average temperature observed during that time.

** Five years of temperature data were missing from the normal period for Evansville, one year of temp data was missing from Poplar Bluff and Carbondale.
