According to the above Storm Prediction Center outlook, a slight risk of severe weather exists from central Kentucky into Tennessee and the northern half of Alabama. This risk covers over 60,000 square miles and just under 8 million people. Large cities such as Nashville, Birmingham, and Chattanooga are under the gun for this severe weather risk.
Latest high resolution model forecasts have a mess of rain and snow covering Indiana, Ohio, Illinois and other areas near Kentucky. Shortly after this mess departs, a complex of severe thunderstorms appears to be forming in the early morning hours over the region delineated above. Composite reflectivities show this complex to be scattered yet organized. It looks like this complex will have a threat for all types of severe weather, but the lack of individual supercells lowers the tornado threat modestly.
