Louisville is starting Sunday with clear skies, calm air and a temperature around 54 degrees, but the day is headed for a much warmer finish. Mostly sunny skies will push the high close to 78, with no rain in the forecast and only a light north breeze.

Cooler Monday, Then The Thermometer Climbs

Tonight stays mostly clear, with temperatures falling to about 51 degrees. Monday will be sunny and cooler, topping out near 73, while Monday night drops to around 47; a northeast breeze will make the afternoon feel crisp rather than summery.

According to the National Weather Service Louisville, Tuesday remains sunny near 75 before a late-week warmup takes over. Highs are forecast near 82 Wednesday, 80 Thursday and 82 Friday, with overnight lows mostly in the upper 40s to mid-50s.

Dry Stretch Holds Through Most Of The Week

Rain chances stay near zero through Friday, making the next several days favorable for commutes, outdoor plans and early fall yardwork. Saturday should still be mostly sunny and near 82, although a slight chance of showers arrives after 2 a.m. Saturday night.

The only minor morning wrinkle is the possibility of shallow fog in low-lying areas early Sunday, October 4, especially across the Bluegrass area. No watches, warnings or advisories are in effect for the Louisville forecast area.
