The first thing you have to know about public schools and their admins. The will close the school and take a day off for the smallest of reasons. They closed the already closed school one day in my neighborhood when parents had to pick up school supplies at the school. They closed it because of "Air Quality" when you are outside picking things up. There had been a forest fire one state over and the smoke was blowing this way. They will close at the drop of a dildo.
