According to its website, all will let out 15 minutes early Thursday through Tuesday.
The message states that the change is in an effort to have "children arrive home in a timelier manner in the afternoon."
"However, the difficult road and weather conditions may continue to cause travel delays as we begin the new school year," the site reads. "Please be aware that your child's arrival time for the next four days may be more varied than usual as everyone adjusts during these first few days of school."
Regular dismissal times will take effect again after Tuesday. Between now and then, Brewster and Southeast will likely see scattered showers and thunderstorms, with rain heavy at times, according to the National Weather Service.
