Will There Be a Snow Day Tomorrow?
The overnight forecast decides most snow days. Get your live score now — then know when to check back.
When will you actually know?
- Big, obvious storms: many districts announce the evening before, often 8–10 PM.
- Borderline storms: the 4–6 AM window — officials check real road conditions at dawn.
- Announcements come via district text alerts, websites, local TV, and robocalls — sign up for your district's alert system now, before you need it.
What matters most for “tomorrow”
Overnight accumulation is king. Snow that falls between midnight and 6 AM — before plows finish and buses roll — drives most closure decisions. That is why our model gives a +10% adjustment to snow in the 4–7 AM window: it is the highest-signal period in the whole forecast.
Your evening checklist
- Run the calculator now for tonight's forecast snapshot.
- Check again after 9 PM — evening model runs sharpen the overnight picture.
- Set an alarm 30 minutes early and re-check district announcements at 5:30 AM.
- Have a backup childcare plan whenever the score is above 40%.
