December weather forecast
Kentucky, USA

December in Kentucky welcomes the official start of winter, displaying a stark contrast to the mild and vibrant fall months. Daytime temperatures often fluctuate between 40°F (4.4°C) and 55°F (12.8°C). At night, the mercury can dip to between 25°F (-3.9°C) and 35°F (1.7°C), a clear indication of the colder conditions that dominate this time of the year.

Louisville and Lexington, as major urban centers, begin to see the occasional snowfall, although accumulations are generally light. The frequency of frosty mornings increases, especially in the northern and eastern regions. Precipitation varies; while snow is less common in the south, northern areas could experience their first significant snowfall events.

Compared to November, December is notably colder and brings a shift in atmospheric conditions. Gone are the last remnants of colorful autumn foliage; in their place stand barren trees and, occasionally, snow-covered landscapes. The decrease in temperature is most felt during early mornings and late evenings, making thermal wear a necessity for outdoor activities.

December serves as a precursor to the even colder and snowier months of January and February. It acts as an introductory phase to the heart of winter, offering a mix of chilly days and freezing nights. While December does not generally feature extreme cold, it nonetheless marks a distinct departure from the moderate climate of preceding months.

Snowfall, while not abundant, becomes increasingly likely as the month progresses. Southern parts of the state might still escape with minimal to no snow, but in the north and east, a white Christmas is not outside the realm of possibility. It is this combination of dipping temperatures and periodic snowfall that cements December's role as the gateway to Kentucky's winter season.
