* The specific temperature: There's no universal temperature threshold. Some areas might close schools at -10°F (-23°C), while others might remain open at much lower temperatures.
* Wind chill: Wind chill significantly impacts how cold it feels. A school might close due to a dangerously low wind chill, even if the actual temperature isn't extremely low.
* Transportation issues: Bus routes may become impassable due to icy roads or extreme cold affecting bus engines. This is a major reason for school closures.
* Building infrastructure: Older buildings might struggle to maintain adequate heat in extreme cold, making them unsafe or uncomfortable for students and staff.
* District policy: Each school district has its own policies and procedures regarding inclement weather closures.
In short, while bitterly cold temperatures *can* lead to school closures, it's not a guaranteed outcome. Parents should check their school district's website or local news for announcements regarding closures.
