A National Weather Service update predicts Will County will see a mix of freezing rain, sleet and snow will continue overnight and diminish between 3 a.m. and 5 a.m.
NWS predicts a coating of ice in one tenth to two tenths of an inch and sleet accumulations between one inch and two. The NWS continues to caution that travel will be slippery.
There is still spotty freezing drizzle that will occur after the main precipitation has ended.
Will County is under a Winter Weather Advisory beginning at 9 p.m. Saturday night and continuing to about 9 a.m. Sunday morning.
The forecast details rain turning into sleet and snow. A representation at the National Weather Service in Romeoville said that unlike the last local advisory, which did not result in much precipitation at all, this one will definitely have precipitation. It is hard to predict exactly what that will look like, though.
"I think it's going to be quite a bit of freezing rain and sleet," Gino Izzi, NWS meteorologist said.
He expected that the bulk of the precipitation would wrap up by 3 a.m. or 4 a.m., but that a light freezing rain could continue to fall into Sunday morning.
The NWS advisory cautioned drivers to take care on roads that could become slippery as the night wears on.
"Even though it will be minor, it will still cause difficult travel conditions," Joliet Weather Center cautioned on its Facebook page. "Ice and snow accumulations generally will be minor, 1-2" throughout the area, but with the combo of precipitation it will certainly cause icy and slick roads."
