In most cases, roads will simply dry off without problems.
However, with light winds and clearing skies, a few icy spots can develop on untreated surfaces.
The ice would be clear and difficult to distinguish between wet areas. This phenomenon is known as black ice.
The icy spots can form even though the air temperature may hover above freezing. When the air becomes dry, the wet surface can cool to the point where ice can form.
According to AccuWeather.com Forensics, each year in the United States black ice contributes to a large number of slip and fall injuries and auto accidents.
Air temperatures will drop below freezing well north and west of the city Tuesday night. As a result, slush will freeze and icy spots will be more common heading out on I-66, I-70 and I-83, the secondary roads that join them and others roadways south and east of the city.
