...Scattered Showers & Thunderstorms Possible Tonight...

Other than some radar returns across South Central Kentucky, most will likely see a fifth straight day of dry conditions. Chances will increase significantly on Thursday. Scattered to numerous showers and storms are anticipated. Some strong to severe activity cannot be ruled out. Heavy rain will be the main threat, but high winds and some hail is also on the table. Look for this scattered activity to continue both Friday and Saturday afternoons. If you haven't baled and stored hay already, do so as soon as possible.
