It reads the National Weather Service forecast for Mount Vernon 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 Mount Vernon’s own big snow morning: 6.5 inches, the top tenth of snowy weekday mornings at a NOAA weather station 9.9 miles away.

The odds of a closing or a delay on the next three school mornings in Mount Vernon, measured against Mount Vernon's own big snow morning of 6.5 inches.

The New York rule

How New York counts a lost day

New York requires 180 days of session plus 900 hours a year for kindergarten to grade 6 and 990 hours for grades 7 to 12. The Commissioner can excuse up to 5 days closed for extraordinary weather, but only if the district cannot make them up by using all its scheduled vacation days before the June Regents exams.

The New York rules in the agency’s own words, and every New York district
