Cincinnati, OH – Drivers across parts of Ohio and the Ohio Valley could encounter patchy fog overnight, potentially impacting the Tuesday morning commute, according to the National Weather Service.
According to the National Weather Service Wilmington, Ohio office, areas of fog may develop late Monday night and persist into early Tuesday morning, particularly in southern and central Ohio, southeast Indiana, and northern Kentucky. Forecasters say visibility could drop to under one mile in some locations, especially in low-lying and rural areas.
The fog risk increases overnight as calm winds and lingering moisture combine under clear skies. The greatest concern window is after midnight through around 8 a.m. Tuesday, when commuters, school buses, and early-morning travelers may face sudden visibility changes.
Maps shared by the National Weather Service highlight pockets of reduced visibility near the Cincinnati metro area, along the Ohio River, and extending into parts of central Kentucky and southern Indiana. While not everyone will see dense fog, officials stress conditions can change quickly from mile to mile.
The NWS recommends drivers slow down, use low-beam headlights, and allow extra travel time if fog develops. Motorists are also urged to avoid using high beams, which can reflect off fog and worsen visibility.
Fog is expected to gradually lift after sunrise Tuesday as temperatures warm and mixing improves. No widespread delays or cancellations have been announced, but residents are encouraged to check local conditions before heading out.
Weather officials will continue monitoring overnight conditions and provide updates if fog becomes more widespread or denser than currently expected.
