About 36.5 inches a winter at a NOAA weather station 6.5 miles away, averaged over 10 winters. Between December 1 and March 31 that brings 2.9 weekday mornings a year with 2 inches of new snow or more, and 0.6 with 4 inches or more.

Q: What was the biggest snow day near Brandon?

9.4 inches on March 4, 2023, the largest single day at a NOAA weather station 6.5 miles away in 10 winters. The snowiest winter was 2017 to 2018, with 57.7 inches.

Q: How does the Brandon snow day predictor work?

It reads the National Weather Service forecast for Ortonville 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 Brandon’s own big snow morning: 2.4 inches, the top tenth of snowy weekday mornings at a NOAA weather station 6.5 miles away.

Q: How far ahead does the Brandon 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 odds of a closing or a delay on the next three school mornings in Brandon, measured against Brandon's own big snow morning of 2.4 inches.

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.
