May 27, 2027, on the district’s 2026 to 2027 calendar.

Q: How much snow does Caldwell get?

About 14.1 inches a winter at a NOAA weather station 12 miles away, averaged over 8 winters. Between December 1 and March 31 that brings 2.3 weekday mornings a year with 2 inches of new snow or more, and 0.9 with 4 inches or more.

Q: What was the biggest snow day near Vallivue?

9 inches on February 15, 2021, the largest single day at a NOAA weather station 12 miles away in 8 winters. The snowiest winter was 2016 to 2017, with 37 inches.

Q: How does the Vallivue snow day predictor work?

It reads the National Weather Service forecast for Caldwell 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 Vallivue’s own big snow morning: 4 inches, the top tenth of snowy weekday mornings at a NOAA weather station 12 miles away.

The Idaho rule

How Idaho counts a lost day

Idaho requires at least 990 instructional hours for grades 9 to 12, 900 for grades 4 to 8, 810 for grades 1 to 3 and 450 for kindergarten. With local board approval, up to 11 hours of emergency closures for bad weather or facility failures can come off the yearly hours requirement.
