Severe Weather Assessment:
Unseasonably warm temperatures, abundant low level moisture, and a very unstable atmosphere blanketed Missouri and Illinois ahead of a late summer cold front. During the afternoon thunderstorms were initiated along and behind a cold front across Northern Missouri and West-Central Illinois. The storms quickly became severe with large hail and damaging winds causing damage to several communities including Hannibal and Quincy.

A weak tornado formed across Southeast Adams County which primarily caused damage to trees and small structures and outbuildings. Additional severe thunderstorms formed across Central Missouri and raced eastward along Interstate 70 causing wind damage along their path.

The storms continued east into Illinois causing sporadic wind damage from Madison to Marion counties. More severe weather was experienced across Southeast Missouri overnight as the cold front moved southward through the remainder of the county warning area.
