Louisville, Ky. – Kentucky drivers could face patches of morning fog along I-64 and I-65 Thursday, but clear skies will dominate as August closes. The calm pattern brings comfortable days and cool nights, making conditions favorable for travel into Labor Day weekend.
According to the National Weather Service in Louisville, temperatures Thursday will climb to 82°F under sunny skies with light winds. Overnight lows dip to the upper 50s, creating conditions for fog in river valleys and on major routes. Drivers heading out early should allow extra time and keep headlights on low beam.
Friday and Saturday remain sunny, with highs between 78°F and 81°F. By evening, temperatures fall quickly, reaching near 56°F, which may again trigger fog patches on rural roads and highways. The calm setup offers little rain risk, but it does mean strong temperature swings between day and night.
With Labor Day travel expected to increase beginning Sunday, officials urge caution on interstates I-64, I-65, and I-71. Evening visibility issues could affect late-night traffic, especially in low-lying areas around the Ohio River. Travelers should plan rest stops and avoid drowsy driving during overnight hours.
The good news for holiday plans: clear skies continue through Labor Day Monday, with highs near 82°F and low humidity. Outdoor events and backyard barbecues should enjoy nearly perfect weather.
Conditions stay stable through early next week, though minor morning fog may remain a factor for commuters and travelers until Tuesday.
