They close schools on sunny days too. I remember when I was sitting in a classroom sweating to death. We had windows open with no AC. In today's World of children, if they aren't lkept perfectly comfortable, they are sent home.
Apparently schools close early on a "perception" of what they "assume" or"think" may occur with their Crystal Ball. I don't want to ask them what the Power Ball numbers are though. Because even with their assumption ability and their wonderful ability to "think" things through as well as their Crystal Ball, I suspect they will still be wrong. Maybe all of the kids on St. George's Island might get their feet wet.
My Brother in Law said the St. Mary's County School system text him YESTERDAY that schools will be closing two hours early today. Of coruse to any of the "doubters" out there, they will say it is all necessary to "air on the side of caution".
