The weather can be bad sometimes but we can't stop everything for a watch. I "watch" is exactly that, a "watch". If the weather seems unusually bad that day then maybe wait if you would like but the school will take precautions also. I am one that does not run to the basement every time the siren sounds, I just watch and go by my instincts. (that's how I have grown up). Do what feels right for you, but be careful because if you show to much stress during a storm (a watch) then your children will learn that also. Say a prayer, and hang in there.
