How do you know what schools in Madison County are closed on a certain day?

There's no single, universal source to check school closings for all schools in Madison County across all states. Madison County exists in multiple states. To find out which schools are closed on a particular day, you need to specify *which* Madison County you're interested in (e.g., Madison County, Alabama; Madison County, New York; etc.).

Once you've specified the county, you can typically find this information through:

* The school district's website: Most school districts have websites with announcements about closures due to weather, emergencies, or other reasons. Look for a "News," "Announcements," or "Closings" section.

* Local news websites and television stations: These often have up-to-the-minute reports on school closings. Search for "[Madison County, State] school closings" on your preferred news source.

* Social media: Many schools and districts use social media (Facebook, Twitter, etc.) to announce closures. Search for the school district's pages.

* Local radio stations: Radio stations often provide updates on school closings, especially during inclement weather.

In short: You need to specify the state first, then check the local news and school district websites for that particular Madison County.
