What really decides a snow day?
- Timing: snow falling between about 3 a.m. and 8 a.m. is the most likely to close schools, because roads cannot be cleared before buses run.
- Ice: even a thin glaze of freezing rain is often more dangerous than several inches of snow.
- Where you live: 2 inches can close schools in Atlanta, while Buffalo may stay open with 8.
- Cold: extreme wind chills can close schools even without snow.
- Snow days used: districts with few make-up days left may choose delays or remote learning instead.
