The National Weather Service office in Paducah points out that in recent years several damaging storms have been spawned in September, October and November, including 2013's deadly Brookport tornado.
It was last November 17 when a twister formed in western McCracken County, crossed the Ohio River and devastated Brookport and Unionville in southern Illinois with 145-mph winds. There were also tornadoes reported near Eddyville and Shawneetown that day, part of 72 tornadoes in seven states during the largest November outbreak in eight years.
Last Halloween was another record outbreak for our area, with 17 tornadoes. Separate November twisters in 2005 killed 25 in Evansville and injured 27 while tracking from Marshall County to Madisonville. September 2006 saw ten tornadoes in our region, and in 2007 there were 16 more in an October cluster.
Meteorologists point out that late September, October and much of November typically bring more favorable conditions for tornadoes and other severe thunderstorm events such as large hail and damaging thunderstorm winds. This increase is driven by a more dynamic atmosphere that occurs during the fall transition to cooler temperatures.
