Greeley School District 6 Snow Day Predictor

Q: How much snow does Greeley get?

About 26 inches a winter at a NOAA weather station under a mile away, averaged over 10 winters. Between December 1 and March 31 that brings 2.1 weekday mornings a year with 2 inches of new snow or more, and 0.5 with 4 inches or more.

Q: What was the biggest snow day near Greeley?

9 inches on February 10, 2024, the largest single day at a NOAA weather station under a mile away in 10 winters. The snowiest winter was 2019 to 2020, with 44.8 inches.

Q: How does the Greeley snow day predictor work?

It reads the National Weather Service forecast for Greeley 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 Greeley’s own big snow morning: 3.8 inches, the top tenth of snowy weekday mornings at a NOAA weather station under a mile away.

Q: How far ahead does the Greeley snow day predictor look?

Three school mornings, as far as the National Weather Service hourly forecast reaches. Weekends and breaks are skipped, so a Friday storm is read for Monday’s buses.

The Colorado rule

How Colorado counts a lost day

Colorado requires at least 160 days, with 1,080 scheduled hours in secondary school and 990 in elementary. The scheduled hours can drop to 1,056 (secondary), 968 (elementary), 870 (full-day kindergarten) or 435 (half-day kindergarten) to cover conferences, staff training and closings the board judges necessary for student health, safety or welfare.
