It wasn't immediately clear why the interstate signs early Thursday warned of a winter storm watch when none had been issued. The signs also warn that black ice is possible in the metro area.
National Weather Service meteorologist Brian Lynn said shortly before 6 a.m. that the messages appeared to be a mistake and should be taken down. He said the weather service contacted state officials to alert them to the messages and asked that they be changed.
The weather service is forecasting some precipitation, saying the greatest concern will be thin, patchy black ice as temperatures fall.
