Overview

A strong fall cyclone crossing the upper midwest combined with an unseasonable surge of moisture into the Ohio valley set the stage for a fall tornado outbreak. Numerous tornadoes were observed across the deep south, Tennessee valley and Ohio valley. Several killer tornadoes were observed including 2 in the Ohio valley. The strongest tornado recorded on this day was the Van Wert F4.

Due to the magnitude of this event, a service assessment team was formed to examine the warning and forecast services provided to emergency managers (EMs), government agencies, and the public. Service assessments provide a valuable contribution to ongoing efforts to improve the quality and timeliness of our products and services. Findings and recommendations from this assessment will help improve techniques, products, services, and the information provided to the American public.
