Greenway Public School District Snow Day Predictor

Q: How much snow does Coleraine get?

About 56 inches a winter at a NOAA weather station 4.3 miles away, averaged over 8 winters. Between December 1 and March 31 that brings 5.3 weekday mornings a year with 2 inches of new snow or more, and 1.5 with 4 inches or more.

Q: What was the biggest snow day near Greenway?

17 inches on November 18, 2016, the largest single day at a NOAA weather station 4.3 miles away in 8 winters. The snowiest winter was 2022 to 2023, with 78.7 inches.

Q: How does the Greenway snow day predictor work?

It reads the National Weather Service forecast for Coleraine 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 Greenway’s own big snow morning: 3.2 inches, the top tenth of snowy weekday mornings at a NOAA weather station 4.3 miles away.

Q: Can Minnesota schools hold a remote day instead?

A district or charter school with an adopted plan may hold up to five e-learning days a year for bad weather, and each one counts as a day of instruction.

The odds of a closing or a delay on the next three school mornings in Greenway, measured against Greenway's own big snow morning of 3.2 inches.
