Hartford Joint No. 1 School District Snow Day Predictor

Q: How much snow does Hartford get?

About 37.1 inches a winter at a NOAA weather station 1.6 miles away, averaged over 10 winters. Between December 1 and March 31 that brings 4.5 weekday mornings a year with 2 inches of new snow or more, and 1.6 with 4 inches or more.

Q: What was the biggest snow day near Hartford Joint No. 1?

12.2 inches on January 13, 2024, the largest single day at a NOAA weather station 1.6 miles away in 10 winters. The snowiest winter was 2018 to 2019, with 48.2 inches.

Q: How does the Hartford Joint No. 1 snow day predictor work?

It reads the National Weather Service forecast for Hartford 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 Hartford Joint No. 1’s own big snow morning: 4 inches, the top tenth of snowy weekday mornings at a NOAA weather station 1.6 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 Hartford Joint No. 1, measured against Hartford Joint No. 1's own big snow morning of 4 inches.
