Freezing rain will be light; snow, strong wind on weekend
The National Weather Service reports light freezing rain and freezing drizzle is likely tonight; areas of light freezing rain and freezing drizzle is expected to develop behind a slow moving cold front this evening and overnight tonight.
Ice accumulations will be under a tenth of an inch.
Untreated roads, as well as less traveled roads, will be most susceptible to any icing.
The ice accumulation threat is expected to end by daybreak Friday.
A freezing rain advisory means that periods of freezing rain or freezing drizzle will cause travel difficulties.
Be prepared for slippery roads. Slow down and be careful while traveling.
This hazardous weather outlook is for portions of north central Illinois, northwest Illinois, west central Illinois, east central Iowa, northeast Iowa, southeast Iowa, including Jefferson County, and northeast Missouri.
Locations most at risk of ice accumulation should be northwest of a line from Freeport, Ill., to Memphis, Mo.
Areas of locally dense fog with visibilities of a half mile or less are also possible.
This weekend a potent winter storm with the potential for high impacts will track from the southern plains into the Ohio Valley.
While initially there may be a period of freezing rain, snow and sleet on Saturday — moderate to possibly heavy snowfall and strong winds are expected Saturday night and Sunday across much of the outlook area.
