Clear skies, light winds, and lingering low-level moisture are helping areas of valley fog to develop and become dense early this morning. This fog will continue to expand but likely be thickest in the valleys. Visibilities will be below a quarter of a mile at times in the worst of the fog. Be sure to slow down and use your low beam headlights when you encounter any fog.

Patchy fog, some locally dense, is developing across parts of south central Kentucky. The fog is most dense in low lying areas and near rivers and lakes. Drivers early this morning should be prepared for rapid changes in visibility. If you encounter dense fog, slow down, use your low beam headlights, and leave plenty of stopping distance between vehicles.
