KENTUCKY — A snowfall of up to a foot from a single weather system in March is uncommon in Kentucky, but historical weather data shows that it is still possible under the right conditions.
March is typically a transitional month in Kentucky as the state moves from winter into early spring, according to the National Weather Service.
Average temperatures begin to climb, but cold air can still occasionally settle across the region. When that lingering cold air combines with a strong storm system moving through the Ohio Valley, the atmosphere can still support significant snowfall.
Historical weather records show that Kentucky has experienced several late season winter storms in March that produced heavy snow totals. One of the most notable examples occurred during the 1993 Storm of the Century, which brought widespread snowfall of more than a foot across parts of the state. In some eastern Kentucky communities, snowfall totals exceeded 20 inches during that storm.
Other March storms have also produced significant snowfall in Kentucky, particularly when low pressure systems track across the Gulf Coast and move northeast through the Appalachians. These systems can draw moisture from the Gulf of Mexico while cold air remains in place across the region, creating conditions favorable for heavy snow.
Topography also plays a role. Areas in eastern Kentucky and higher elevations of the Appalachian region can see heavier accumulations when moist air is lifted over the mountains, increasing snowfall rates.
While large snowfalls become less common as spring approaches, past weather data shows that Kentucky can still experience major winter storms in March. Under the right atmospheric setup, a single system is capable of producing snowfall totals approaching or exceeding a foot in parts of the state.
