Light rain will move over Kentuckiana late this afternoon through the overnight. Temperatures will be hovering near the freezing mark in southern Indiana, so we'll have to watch for light freezing rain north of Louisville tonight.
Notice the map of precipitation types below. The best chance for light icing will be from a line from Madison to Paoli, Indiana and north - especially along Highway 50 from North Vernon, Seymour, to Bedford. The freezing/sleet will be light, but still could cause slick roads and hazardous driving conditions. This is a short-lived system, moving out at or before sunrise Saturday morning.
The map below shows the counties in Gray, which are under a Winter Weather Advisory. This includes Jackson, Jennings, Lawrence counties in Indiana from 4pm today through 5am Saturday. Also, Carroll county, Kentucky from 6pm today until 11am Saturday.
Temperatures warm to near 60 Sunday, and this warm-up will lead to a chance of strong storm Sunday night.
