Can closed schools (due to waether) reopen if the predicted forecast turns out be false?

Yes, closed schools due to weather can reopen if the predicted forecast turns out to be false and conditions improve significantly. However, the decision rests with the school administration and local authorities. They will consider several factors including:

* Current conditions: Is the weather actually improved to a safe level for travel and operations? A false prediction doesn't automatically mean it's safe.

* Road conditions: Even if the weather has improved, roads may still be icy, flooded, or otherwise hazardous.

* Building safety: Was there any damage to the school building due to the weather?

* Bus routes: Are bus routes safe and passable?

* Staff availability: Will enough staff be able to get to school safely?

Essentially, they'll assess the situation on the ground, not just rely on the updated forecast. They may announce a reopening in the morning, or even later in the day, if the improvement is significant enough.
