Fire Weather Planning Forecast for Central Kentucky and Southern Indiana
National Weather Service Louisville KY
350 AM EDT Sat Sep 19 2026

.DISCUSSION...

Hot and humid conditions will continue through Sunday across
northern Kentucky and southern Indiana, and through Monday over
southern and central Kentucky. While most locations will stay dry,
any thunderstorms (20-40% chance) both this afternoon and
tomorrow could dump heavy rainfall over 1 inch and also generate
locally strong wind gusts. Winds should flip around from the
southeast this morning to southwest this afternoon, though
generally staying under 10 kt outside of any thunderstorms. This
will limit ventilation despite deep mixing. More numerous
thunderstorms are forecast ahead of a cool front Monday into
Tuesday, with cooler and drier conditions arriving in its wake.
