New London School District Snow Day Predictor

Q: How much snow does New London get?

About 27.3 inches a winter at a NOAA weather station 1 mile away, averaged over 10 winters. Between December 1 and March 31 that brings 2.3 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 New London?

17 inches on February 23, 2026, the largest single day at a NOAA weather station 1 mile away in 10 winters. The snowiest winter was 2025 to 2026, with 55.8 inches.

Q: How does the New London snow day predictor work?

It reads the National Weather Service forecast for New London 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 New London’s own big snow morning: 5.4 inches, the top tenth of snowy weekday mornings at a NOAA weather station 1 mile 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 New London, measured against New London's own big snow morning of 5.4 inches.
