About 23.8 inches a winter at a NOAA weather station 2.5 miles away, averaged over 10 winters. Between December 1 and March 31 that brings 2.2 weekday mornings a year with 2 inches of new snow or more, and 0.7 with 4 inches or more.

6.7 inches on November 12, 2019, the largest single day at a NOAA weather station 2.5 miles away in 10 winters. The snowiest winter was 2017 to 2018, with 43 inches.

It reads the National Weather Service forecast for Dearborn 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 Dearborn’s own big snow morning: 3 inches, the top tenth of snowy weekday mornings at a NOAA weather station 2.5 miles away.

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.
