Manheim Central School District Snow Day Predictor

Q: How much snow does Manheim get?

About 21.9 inches a winter at a NOAA weather station 4.4 miles away, averaged over 7 winters. Between December 1 and March 31 that brings 2.6 weekday mornings a year with 2 inches of new snow or more, and 1.1 with 4 inches or more.

Q: What was the biggest snow day near Manheim?

10.1 inches on March 22, 2018, the largest single day at a NOAA weather station 4.4 miles away in 7 winters. The snowiest winter was 2020 to 2021, with 37.9 inches.

Q: How does the Manheim snow day predictor work?

It reads the National Weather Service forecast for Manheim 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 Manheim’s own big snow morning: 4.6 inches, the top tenth of snowy weekday mornings at a NOAA weather station 4.4 miles away.

Q: Can Pennsylvania schools hold a remote day instead?

A district with a PDE accepted plan can turn up to five closure days a year, including snow days, into Flexible Instructional Days that count as school days; they can be online, offline or both.

The odds of a closing or a delay on the next three school mornings in Manheim, measured against Manheim's own big snow morning of 4.6 inches.

The Pennsylvania rule

How Pennsylvania counts a lost day

Pennsylvania requires either 180 days, or hours: 900 for kindergarten through grade 6 and 990 for grades 7 to 12, as the district chooses. The state forgives no days; districts are expected to build make-up days into the calendar for closures beyond any Flexible Instructional Days.
