A band of occasionally heavy snow moved across southern Indiana and north central Kentucky during the early morning hours Monday. Snow fell at an intense rate at times, with over an inch of snow falling in less than one hour across Jefferson County around 1 am EST. From a personal observation here at the National Weather Service, some of the snowflakes during the heaviest of the snow (around 1am EST) were the size of half dollars.
Below is a "very rough" map of how much snow fell across southern Indiana and northern Kentucky. The band of heaviest snow fell within the inner circle shown below. In general, 3 to as much as 5 inches fell from Crawford County east along and north of Interstate 64 through Louisville, Frankfort, and Lexington. One to 3 inches fell within the outer circle, including areas such as Madison, Indiana, northern Bullitt County, and Harrison and Nicholas Counties in Kentucky.
