Southern Indiana and central Kentucky enjoy clear skies and mild temperatures this week, with a cold front bringing cooler air early next week.

Clear Skies and Cool Temperatures Continue Across Kentucky Before Weekend Warm-Up

Louisville — Issued by the National Weather Service at 12:48 AM on October 9, 2024.

Cool Nights and Pleasant Days as High Pressure Dominates Kentucky Weather

A period of tranquil weather is set to continue across Kentucky and southern Indiana as high pressure maintains its hold over the region. Overnight lows will drop into the upper 30s in the cooler valleys, with most areas seeing temperatures in the 40s by Wednesday morning. Despite the chilly nights, clear skies and dry conditions will allow for pleasant afternoons, with highs reaching the mid to upper 70s on Wednesday.

Some patchy fog may develop in valley locations overnight, but it will be minimal and short-lived. Winds will be light, maintaining a northerly direction through Wednesday.

Warmer Weekend Expected Before Cold Front Arrives

As high pressure shifts eastward later this week, southern Indiana and central Kentucky will experience a gradual warming trend. By Friday, temperatures will rise into the low 80s, particularly west of Interstate 65. The warm weather will persist into Saturday, marking an exceptionally mild end to the work week.

However, a significant pattern change will take place by Sunday as a large low-pressure system over Canada pushes a cold front through the region. This front will bring cooler air, switching southwest winds to northwest, but precipitation is not expected due to the dry air mass.

Cold Air Returns Early Next Week

By Monday, high temperatures will only reach the 60s, with even cooler conditions expected on Tuesday, when some areas may struggle to rise out of the 50s. Overnight lows will dip into the 30s, and parts of Kentucky could experience their first frost of the season early next week.
