Should it become necessary to close school because of the weather, the superintendent will notify local radio and television stations before 6:00 AM, if at all possible. If a decision can be made the night before in case of snow or freezing conditions, an announcement of school closings will be made prior to the 6:00 PM or 10:00 PM television and radio newcasts. Parents should not call schools, school officals, or radio and television stations. It is essintial that telephone lines be kept open. Mayfield Independant Schools use "SchoolCast" phone messaging to deliver automated phone calls to inform every household in the district of school announcements.
