The National Weather Service in Buffalo has issued a winter weather advisory beginning at 10 o'clock tonight and stretching overnight to about 9 o'clock Wednesday morning. We should expect to see "mixed precipitation" that should start out as freezing rain but soon turn to rain only.
From the National Weather Service:
Light snow will overspread the region tonight, then change over to a mix of freezing rain and sleet for a few hours overnight before transitioning to all rain by mid Wednesday morning. A general 1 to 3 inches of snow is expected, along with the potential for up to one to two tenths of an inch of ice accumulation, with the greatest amounts of ice accumulation most likely across interior sections of the Finger Lakes, Genesee Valley and Western Southern Tier. Any such ice accumulation will result in hazardous driving conditions on any untreated roadways later tonight and early Wednesday.
A winger weather advisory for mixed precipitation is issued when some icing is forecast to develop, but accumulations are expected to be light. Any accumulation would make driving and walking difficult but not impossible on untreated roads and sidewalks. If you will be driving be especially careful on bridges and overpasses and allow extra time to reach your destination.
