A cold front was moving eastward across western Kentucky around midday on December 9th. Aloft we had a strong mid and upper level jet streak across the Midwest with Kentucky and Tennessee in the favored right entrance region for thunderstorm development.

The airmass had become quite unstable by Noon across western Tennessee and into far southern portions of west Kentucky (SBCAPE in excess of 1000 j/kg). As is commonly the case during the cool season, we had plenty of wind shear present with both low level and deep layer values supportive for damaging winds and tornado threats with any thunderstorms.
