June 11, 2027, on the district’s 2026 to 2027 calendar.

Q: How much snow does Shelburne get?

About 63.3 inches a winter at a NOAA weather station 3.5 miles away, averaged over 7 winters. Between December 1 and March 31 that brings 5.1 weekday mornings a year with 2 inches of new snow or more, and 1.9 with 4 inches or more.

Q: How does the Champlain Valley snow day predictor work?

It reads the National Weather Service forecast for Shelburne 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 Champlain Valley’s own big snow morning: 3.5 inches, the top tenth of snowy weekday mornings at a NOAA weather station 3.5 miles away.

The odds of a closing or a delay on the next three school mornings in Champlain Valley, measured against Champlain Valley's own big snow morning of 3.5 inches.

The Vermont rule

How Vermont counts a lost day

Vermont requires at least 175 student attendance days a year, with the school board setting the length of the day. A school closed for a cause beyond the board's control may petition the State Board for a waiver, filed within 10 days of each closing and by June 15; if granted the district is treated as having met the requirement.
