Gloucester Township School District Snow Day Predictor

Q: How much snow does Blackwood get?

About 16.9 inches a winter at a NOAA weather station 2.1 miles away, averaged over 8 winters. Between December 1 and March 31 that brings 2.3 weekday mornings a year with 2 inches of new snow or more, and 0.9 with 4 inches or more.

Q: What was the biggest snow day near Gloucester Township?

16 inches on February 23, 2026, the largest single day at a NOAA weather station 2.1 miles away in 8 winters. The snowiest winter was 2025 to 2026, with 36.7 inches.

Q: How does the Gloucester Township snow day predictor work?

It reads the National Weather Service forecast for Blackwood 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 Gloucester Township’s own big snow morning: 5.4 inches, the top tenth of snowy weekday mornings at a NOAA weather station 2.1 miles away.

Q: Can New Jersey schools hold a remote day instead?

A virtual or remote day counts toward the 180 days only when schools close for more than three consecutive days because of a declared state of emergency, a declared public health emergency or a health agency directive, under a program the commissioner approved.

The odds of a closing or a delay on the next three school mornings in Gloucester Township, measured against Gloucester Township's own big snow morning of 5.4 inches.
