About 47.9 inches a winter at a NOAA weather station 1.5 miles away, averaged over 10 winters. Between December 1 and March 31 that brings 6.4 weekday mornings a year with 2 inches of new snow or more, and 0.8 with 4 inches or more.

9.5 inches on December 16, 2016, the largest single day at a NOAA weather station 1.5 miles away in 10 winters. The snowiest winter was 2022 to 2023, with 77.1 inches.

It reads the National Weather Service forecast for Idaho Falls 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 Idaho Falls’s own big snow morning: 3 inches, the top tenth of snowy weekday mornings at a NOAA weather station 1.5 miles away.

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.
