Colchester School District Snow Day Predictor

Q: How much snow does Colchester get?

About 24.4 inches a winter at a NOAA weather station 12.8 miles away, averaged over 8 winters. Between December 1 and March 31 that brings 2.4 weekday mornings a year with 2 inches of new snow or more, and 1.1 with 4 inches or more.

Q: What was the biggest snow day near Colchester?

15 inches on February 23, 2026, the largest single day at a NOAA weather station 12.8 miles away in 8 winters. The snowiest winter was 2025 to 2026, with 50.1 inches.

Q: How does the Colchester snow day predictor work?

It reads the National Weather Service forecast for Colchester 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 Colchester’s own big snow morning: 4.4 inches, the top tenth of snowy weekday mornings at a NOAA weather station 12.8 miles away.

Q: Can Connecticut schools hold a remote day instead?

A remote learning day counts as an actual school session if it meets the Commissioner's remote learning standards; the statute sets no cap.

The odds of a closing or a delay on the next three school mornings in Colchester, measured against Colchester's own big snow morning of 4.4 inches.
