Louisville, Kentucky – Arctic air is expected to remain an influence across Kentucky from Jan. 24 through Jan. 30, though the strength of the cold signal weakens compared to areas farther north, placing the state near the southern edge of the prolonged winter pattern.
According to the National Weather Service Climate Prediction Center, Kentucky falls within a roughly 50 to 60 percent probability range for below-normal temperatures during the Jan. 24–30 period. This suggests a continued risk for colder-than-average conditions, but with a higher likelihood of temperature swings and brief moderation, especially during the daytime.
Across northern and central Kentucky, including Louisville, Lexington, and the Interstate 64 corridor, daytime highs are expected to trend below late-January averages at times, while overnight lows frequently dip into the teens and 20s. Persistent cold during nighttime hours could allow icy patches to linger on bridges, overpasses, and untreated roadways, particularly during morning commutes.
In eastern Kentucky, including the Appalachian foothills and higher terrain near Pikeville and Hazard, colder air may hold more firmly. Valley locations could see enhanced cold pooling overnight, increasing the risk of refreeze on secondary and mountain roads.
Farther south and west, including Bowling Green and the Pennyrile region, temperatures may fluctuate more noticeably, with occasional milder afternoons followed by cold nights capable of refreezing any lingering moisture.
The Kentucky Transportation Cabinet urges drivers to remain cautious during overnight and early morning travel. Residents are encouraged to monitor temperature changes, protect exposed pipes during colder nights, and stay weather-aware.
While confidence is lower than across the Upper Midwest and Great Lakes, the broader Arctic pattern remains influential, keeping below-normal temperatures a continued possibility across Kentucky through Jan. 30.
