Snow day vs. delay vs. early dismissal
Three ways a district handles bad weather, and what each one says about the storm.

In this guide (3)
| Decision | What happens | Typical weather |
|---|---|---|
| Snow day (closure) | No school all day. | Heavy snow or ice still falling at bus time; extreme cold; roads that won't be clear by mid-morning. |
| Delay (late start) | School opens later, often by 2 hours. Morning programs are usually cancelled. | Snow ends overnight; roads need a few hours of plowing and daylight; bitter cold at dawn. |
| Early dismissal | School closes before the normal end of the day. | A storm that starts during the school day, or worsens faster than forecast. |
| Remote day | Classes move online for the day (where allowed). | Any of the above, in districts that use remote days instead of make-up days. |
How the calculator shows them
- Chance of closure: the chance your district cancels school for the day.
- Chance of a delay: the chance of at least a delay (a delay or a closure). It is never lower than the closure chance.
- Snow that falls during school hours counts less toward a closure, because it usually means an early dismissal instead.
What a delay tells you
A high delay chance with a low closure chance usually means the storm ends before morning: roads will be rough at 6 AM and fine by 9. If the closure chance climbs during the night, the storm is lasting longer or hitting harder at bus time.
Can a delay turn into a closure?
Yes. Districts sometimes announce a delay first and upgrade to a closure once crews see the roads. That is why the calculator keeps updating until 9 AM.
