Louisville, KY – A cold front is sweeping across Kentucky this morning, ushering in noticeably cooler and drier fall air for the remainder of the week. A few brief sprinkles are possible north of I-64 early today, but most of the region will stay dry under partly to mostly sunny skies.
According to the National Weather Service office in Louisville, highs will top out in the upper 60s to lower 70s this afternoon before dropping into the upper 30s and lower 40s overnight. West winds gusting 20 to 25 mph will make it feel cooler through the afternoon, especially across central Kentucky and the Bluegrass region.
By Wednesday and Thursday, skies turn crystal clear with daytime highs in the lower 60s—typical for late October but well below last week’s warmth. According to forecasters, calm winds and low humidity will allow temperatures to dip into the mid-30s across portions of Hardin, Nelson, and Marion counties by early Friday, setting up the first widespread frost potential of the season.
Motorists should expect crisp mornings and excellent visibility for midweek travel, while residents are urged to cover tender plants or bring outdoor vegetation indoors later this week. The NWS notes that patchy frost is most likely in sheltered rural valleys west and south of Louisville.
Clouds will begin to increase Friday as another weak disturbance approaches, though rain chances appear minimal into the weekend. Overall, this week marks a shift to more seasonable, crisp fall weather across the Ohio Valley.
