Top 10 Weather Headlines of 2011


On both a national and a local scale, extreme weather events in 2011 captured our attention. A record-breaking spring flood season dominated the weather news for weeks. Flooding on the Mississippi and Ohio Rivers brought national attention to our region. Record high water levels were observed at several locations on area rivers and lakes. The annual rainfall totals at Paducah and Evansville were the highest on record.

  • The winter of 2010-11 was unusually snowy, especially across western Kentucky. The seasonal snowfall total at Paducah was 18.9 inches, which was the 8th highest on record. The meteorological winter (Dec. 1-Feb. 28) was the 15th coldest on record at Paducah. 
  • The spring severe weather season was very active. The annual tornado count for the Paducah NWS forecast area was the highest since the modernized office opened in 1994. The total number of severe weather events (hail, tornadoes, and damaging winds) was second only to 2006. A table of severe weather stats for 2011 and the past 15 years shows the numbers.
  • The following weather events are ranked unscientifically. The primary rating factors are economic impact, fatalities and injuries, and social impact. The meteorological significance of the event is secondary.

Late April / Early May Flooding - The wettest spring on record at Paducah, KY contributed to record flooding along parts of the Ohio and Mississippi Rivers, as well as Kentucky Lake and Lake Barkley. The economic impact on our local area was in the hundreds of millions of dollars.
