The first appreciable snowfall of the season is expected overnight in a dozen Kentucky counties along the Ohio River.
An approaching Alberta clipper system will spread snow through early tomorrow afternoon.
Kentucky cities under the winter weather message include Versailles, Georgetown and Alexandria.
The advisory is in effect from 7 p.m. today to 4 p.m tomorrow.
Accumulations are expected to be light, but below-freezing temperatures could make bridges and overpasses slick.
