The National Weather Service has issued a Severe Thunderstorm WATCH for all of south central Kentucky until 9pm this evening. The atmosphere across western and central Kentucky continues to become more unstable as we’ve progressed through the afternoon, providing an environment conductive for strong to severe thunderstorm development.
Looking at meteorological parameters, it’s looking more and more likely that we’ll see strong storms develop between now and 9pm this evening.
