A powerful cold front continues to work toward the bluegrass state this evening. This front separates the warm, humid air from the arctic cold moving in behind it. Throw in an increase in wind energy and severe thunderstorms will become likely.

A tornado watch has been issued for much of western Kentucky. It extends as far east as Shelby and Nelson Counties.

Here's a breakdown:

- Our front will press closer to western Kentucky this evening into the overnight. A squall line of thunderstorms will develop and work eastward. Damaging winds will be the main player with this line of storms. We will also have to keep an eye on thunderstorms going up ahead of this main line. That may pose a tornado threat.

- The squall line and severe weather threat will then progress into central and eastern Kentucky late tonight and Wednesday morning. Damaging winds will continue to be the main threat during this time.

- Temps will start in the 60s and fall into the 30s by Wednesday evening. Some snow flurries will be possible during this time.

- Arctic air will continue to funnel in here Thursday and Friday with snow showers possible Thursday. We have two light snow threats… one for Thursday night/Friday and then again on Saturday.

Watches and warnings are very possible across our region later tonight.

I will have updates as needed.
