Delavan-Darien School District Snow Day Predictor

Q: How much snow does Delavan get?

About 34 inches a winter at a NOAA weather station under a mile away, averaged over 10 winters. Between December 1 and March 31 that brings 3.3 weekday mornings a year with 2 inches of new snow or more, and 1.4 with 4 inches or more.

Q: What was the biggest snow day near Delavan-Darien?

10 inches on March 16, 2026, the largest single day at a NOAA weather station under a mile away in 10 winters. The snowiest winter was 2022 to 2023, with 44.5 inches.

Q: How does the Delavan-Darien snow day predictor work?

It reads the National Weather Service forecast for Delavan 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 Delavan-Darien’s own big snow morning: 4 inches, the top tenth of snowy weekday mornings at a NOAA weather station under a mile away.

Q: Can Wisconsin schools hold a remote day instead?

If a district offers make-up instruction virtually on a weather closure, those hours can count; the rule sets no cap on such days.

The odds of a closing or a delay on the next three school mornings in Delavan-Darien, measured against Delavan-Darien's own big snow morning of 4 inches.
