Superintendent Joseph announced that all JPPSS schools and administrative buildings will be closed on Thursday, January 4th due to several consecutive days of freezing temperatures in Jefferson Parish that have taxed the heating systems in its school buildings. The concern is the safety of students who, in the early morning hours, will be exposed to frigid temperatures while waiting for the bus. According to the National Weather Service, frigid temperatures are expected overnight and well into Thursday morning almost to midday.
