Overnight rain in Greater Cincinnati has given some a dusting of snow.
The National Weather Service said temperatures have gotten cold enough for a few places to change to freezing rain but most of the mix has been sleet and snow.
"Light accumulations have been occurring which have been sufficient for some slick roads. This precipitation will come to an end this morning, lingering the longest in Northeast Kentucky," the National Weather Service said.
Most areas will get a break in precipitation through the afternoon, but it will return Thursday evening, bringing freezing rain to some.
Forecasters said some areas could see a light glaze.
Parts of Greater Cincinnati are under a winter weather advisory from 4 a.m. to 10 a.m.
"Freezing rain expected. Total ice accumulations of a few hundredths of an inch," the National Weather Service said. "Slow down and use caution while traveling. Prepare for possible power outages."
