Snow developed along an Arctic cold front as it sliced southeast across western Kentucky during the daytime hours. As the front slowed down over the Tennessee Valley late in the day, a weak surface low developed on the front. This caused snow to persist through the evening hours, and even into early on the 16th from Murray to the Hopkinsville area. The result was heavy snowfall across most of western Kentucky, ranging from 4 to 8 inches. Some specific heavy snowfall reports included 8 inches at Paducah and Benton, 7 inches at Hopkinsville and Mayfield, and 4.5 inches in Madisonville. Where the snow ended sooner across the Henderson and Morganfield areas, amounts were near 3 inches. Visibility was frequently reduced below one mile in the heavy snowfall area. Much of the snow melted on treated road surfaces during the day, but conditions rapidly deteriorated after dark as temperatures dropped through the 20's. Wind chill indices were in the teens during most of the snowstorm. Actual air temperatures fell into the teens as the snow ended. These cold temperatures reduced the effectiveness of road salt, which slowed recovery efforts in the wake of the storm. The new snowfall on top of snow from the January 12th storm raised total snow depths to near a foot in some areas. There were some traffic accidents on the slippery roads. At Mayfield, a ramp at the junction of the Purchase Parkway and U.S. 45 was closed for two days after an accident involving a jackknifed tractor-trailer.
