Closing early for this, except for perhaps the counties along the bay, is so dumb, but IF you are going to close, I totally agree that you have to do it the night before. Nothing changed between last night and this morning. I work from home so I am fortunate that it doesn't really impact me and I can easily get my kids from the bus, but many parents are not that fortunate and this is a huge headache for them. At least let them be able to plan ahead for said huge headache.
I really wish I knew the clowns in charge of these decisions.
