Due to the continued threat of black ice, all schools will operate on a two-hour delay Thursday. This means that buses will arrive two hours later than their normal time and that parents should arrive at school to drop off their students two hours later than the normal time. All on-campus Before School programs also will operate on a two-hour delay. "Families and staff should consider their own local conditions, and use their best judgment when traveling. Thank you for your continued partnership as we ensure the safety of students, staff and families.
