Cornwall-Lebanon School District Snow Day Predictor

About 21.5 inches a winter at a NOAA weather station 3.7 miles away, averaged over 10 winters. Between December 1 and March 31 that brings 2.5 weekday mornings a year with 2 inches of new snow or more, and 0.9 with 4 inches or more.

11.6 inches on March 21, 2018, the largest single day at a NOAA weather station 3.7 miles away in 10 winters. The snowiest winter was 2017 to 2018, with 40.8 inches.

It reads the National Weather Service forecast for Lebanon 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 Cornwall-Lebanon’s own big snow morning: 4 inches, the top tenth of snowy weekday mornings at a NOAA weather station 3.7 miles away.

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.

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.
