The National Weather Service reports that rain showers will change to a rain/snow mix and then all snow across southern Indiana. Accumulating snow appears likely by midnight and after, with around 2 to 4 inches of accumulation expected. Some portions of southern Indiana could see as much as 4 to 6 inches of snow.
North-central Kentucky over to the Bluegrass region should expect 1 to 4 inches of accumulation before the majority of precipitation ends around daybreak.
Expect a relative lull in wintry precipitation through the late morning and early afternoon on Saturday, but by mid to late afternoon, scattered snow showers will again develop across much of the area. Some of the snow showers could produce a quick burst of snow, causing light accumulations and slick conditions through the evening hours on Saturday.
