The Louisville area could be in for its first significant snow of the winter, starting sometime early Thursday.
The National Weather Service said much of Central Kentucky should brace for 2 to 4 inches of snow Thursday.
In anticipation of the snow, 10 Louisville Metro dump trucks began putting down brine, a salt and water mixture, on major snow routes Tuesday and plan to continue Wednesday, said Metro government spokeswoman Allison Martin. The brine is intended to prevent precipitation from freezing on roadways.
A storm system moving up from the Southwest will enter the Ohio Valley overnight, bringing with it "a light, steady snow" that could persist from morning into evening, said Mike Callahan of the weather service.
Slightly less snow -- a maximum of 3 inches -- is predicted for much of Southern Indiana.
