In Nebraska, Polk, York, Dawson, Fillmore, Furnas, Gosper, and Thayer Counties. * WHEN...From 9 PM this evening to noon CST Saturday. * IMPACTS...Low visibility could make driving conditions hazardous, and freezing fog could deposit a thin layer of ice on untreated roads and bridges, making them slick. * ADDITIONAL DETAILS...Conditions will likely vary across the Advisory area, with fog worsening in some areas before others tonight, and also improving in some areas before others Saturday morning. However, at some point most places should see visibility drop to around 1/4 mile or less. Even if truly dense fog fails to develop, even lighter freezing fog could cause slick spots on untreated roads and bridges. The portion of this Advisory least likely to experience any dense fog is western Dawson County.
