Q: How does the Napoleon snow day predictor work?

It reads the National Weather Service forecast for Napoleon through the night and the 5 to 8 am bus run, adds winter alerts and the Winter Storm Severity Index, and measures the snow against Napoleon’s own big snow morning: 2.5 inches, the top tenth of snowy weekday mornings at a NOAA weather station 11.6 miles away.

Q: How far ahead does the Napoleon snow day predictor look?

Three school mornings, as far as the National Weather Service hourly forecast reaches. Weekends and breaks are skipped, so a Friday storm is read for Monday’s buses.

The Michigan rule

How Michigan counts a lost day

Michigan requires at least 180 days and 1,098 hours of pupil instruction. The first 6 days (or the same hours) lost to conditions outside the district's control, such as severe storms, are counted as instruction; up to 3 more can be approved by the State Superintendent.
