A Dense Fog Advisory is in effect across western and north-central New York through early Wednesday morning. Expect fog to become widespread again tonight and last through early Wednesday morning. Visibility may be reduced to a quarter mile or less at times.
Precipitation will favor rain to the south, and a wintry mix from the southern Lake Ontario shoreline, Finger Lakes and into the eastern Lake Ontario region.
A mixed bag of precipitation will overspread the area Wednesday, with rain across the Southern Tier, a wintry mix including freezing rain south of Lake Ontario, and snow east of Lake Ontario. Marginal temperatures near freezing and the higher February sun angle may help to keep roads mainly wet through the day, but be alert for slick spots on untreated surfaces.
