Temperatures dipped early Friday morning, causing dangerous driving conditions in some areas.
The formation of black ice on roads caused several delays in school systems in eastern Kentucky.
In Lexington, the cold temperatures caused a water main break on Daniel Court. That's near Versailles Road.
The water leaked from the pipe, then froze on the roadway. That made it difficult for drivers in the area.
There's no word on if that ice caused any accidents.
