The office that handles weather forecasts for Cincinnati and Dayton is the National Weather Service in Wilmington, Ohio. Its page uses the code ILN in several product names. The office is not located in either city; it sits in Wilmington and serves the surrounding region from there.

The site publishes a wide range of forecast products. You can find local graphical forecasts, hourly weather graphs, area forecast graphics, and the area forecast discussion. Aviation forecasts and a forecasters' discussion are also available. For hazards, the office posts a graphical hazardous weather outlook, local product criteria, and pages for winter weather, fire weather, severe weather, and hurricanes. Marine and tropical information appear as well.

River and lake information is another major part of what it publishes. That includes current and past streamflow, ensemble river guidance, river forecast centers, river observations and forecasts maps, and a history page for the Ohio River at Cincinnati. Climate and past weather items include past rainfall, snowfall records, past observed weather, drought outlook, and an ILN climate webpage. Current conditions pages cover air quality, satellite observations, rainfall observations, and snowfall reports.

Radar offerings include local enhanced and standard KILN radar, regional and national standard radar, and enhanced radar from Columbus, Cincinnati, and Dayton TDWR systems. The office also lists current hazards such as river flooding, drought, thunderstorms, and hurricanes, along with briefing pages and a graphical hazardous weather outlook.

Local programs and preparedness material are published too. These include SKYWARN storm spotter information, a spotter training schedule, NOAA Weather Radio details, student and volunteer information, office tours, a weather event archive, and Ohio tornado climatology. There is also a self-briefing page and an emergency response tool. The page lists the office contact address and phone number, and it shows a last map update time, indicating that map products are kept current.
