Probability, 4 to 7 AM window, and a 3-day look.
Snow Day Calculators by City
Local pages for snowy metros, not a national average.
Why this calculator
Built around the 4 to 7 AM decision window and school type.
4 to 7 AM window
We score the hours when buses roll, not a daily snow total.
ECMWF + NOAA
The same family of models TV meteorologists use. Free to run.
School type
Rural routes close earlier than urban streets. The toggle exists for that.
Not official
A planning aid. Your district app and bus message still win.
Snow Day Guides
Inches, ice, delays, and announcement times.
