Marietta City School District Snow Day Predictor

Q: How much snow does Marietta get?

About 8 inches a winter at a NOAA weather station 2.3 miles away, averaged over 10 winters. Between December 1 and March 31 that brings 1.2 weekday mornings a year with 2 inches of new snow or more, and 0.2 with 4 inches or more.

Q: What was the biggest snow day near Marietta?

8 inches on January 25, 2026, the largest single day at a NOAA weather station 2.3 miles away in 10 winters. The snowiest winter was 2021 to 2022, with 19.5 inches.

Q: How does the Marietta snow day predictor work?

It reads the National Weather Service forecast for Marietta 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 Marietta’s own big snow morning: 2.4 inches, the top tenth of snowy weekday mornings at a NOAA weather station 2.3 miles away.

Q: Can Ohio schools hold a remote day instead?

A school can make up the hours of up to three closed days online, including for hazardous weather, if its board adopted a plan by August 1; using it is optional.

The odds of a closing or a delay on the next three school mornings in Marietta, measured against Marietta's own big snow morning of 2.4 inches.

The Ohio rule

How Ohio counts a lost day

Ohio requires hours, not days: 910 hours for full day kindergarten through grade 6, 1,001 hours for grades 7 to 12, 455 for half day kindergarten. Only hours that drop a school below the state minimum must be made up, by extending the school year.
