Patchy dense fog and low clouds have developed across portions of northern Ohio. This mix of fog and low clouds is allowing for variable visibility across the area, including visibility as low as one-quarter of a mile in sheltered locations. Fog may increase in coverage toward sunrise. If traveling across the area, drivers should remain alert for rapid changes in visibility and use low-beam headlights.
