Watertown School District Snow Day Predictor

Q: How much snow does Watertown get?

About 36.7 inches a winter at a NOAA weather station 1.3 miles away, averaged over 10 winters. Between December 1 and March 31 that brings 3.8 weekday mornings a year with 2 inches of new snow or more, and 1.3 with 4 inches or more.

Q: What was the biggest snow day near Watertown?

10 inches on November 30, 2025, the largest single day at a NOAA weather station 1.3 miles away in 10 winters. The snowiest winter was 2022 to 2023, with 49.5 inches.

Q: How does the Watertown snow day predictor work?

It reads the National Weather Service forecast for Watertown 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 Watertown’s own big snow morning: 3.4 inches, the top tenth of snowy weekday mornings at a NOAA weather station 1.3 miles 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 Watertown, measured against Watertown's own big snow morning of 3.4 inches.
