Per the National Weather Service in Louisville:
A cold front will push a band of showers and storms through the region from west to east late tonight into early Monday morning. Some storms could be strong or severe, with gusty winds as the main threat.
Per Meade County Emergency Management Director Ron Dodson:
Right now it looks like the worst of the weather will stay west of our neck of the woods, but if any stronger storms survive this far east, they would come in overnight. Make sure you have a means to receive warnings after you go to bed, be it a NOAA weather radio, making sure you have Wireless Emergency Alerts for weather turned on for your cell phone, etc. The graphic below gives a little more detail.
