Henderson County sits in the NWS Quad Cities warning area along the Illinois-Iowa border and faces a broad range of severe weather threats. Tornadoes are a documented hazard - a violent F4 tornado crossed Hancock, Henderson, and Warren counties in May 1995, and the county has recorded multiple weaker touchdowns historically. Summer derecho and straight-line wind events regularly push 80-95 mph through the region, and large hail accompanies supercell thunderstorms that track northeast across western Illinois. The county's Mississippi River frontage makes it especially vulnerable to riverine flooding, with NWS gauges at Gladstone Lock and Dam 18 frequently entering flood stage during spring rain events. Winters bring ice storms and heavy snow under Alberta Clipper and Gulf moisture setups that the Quad Cities NWS office tracks through its Winter Storm Severity Index.
