Iowa City Community School District Snow Day Predictor

Iowa City announces closings by 6:00 a.m. on the morning of a snow cancellation; by 9:00 p.m. the night before for a cold cancellation, by its own published protocol.

By phone call, email, text message, the district app and social media, and on the district’s own closings page.

June 4, 2027, on the district’s 2026 to 2027 calendar.

About 22.8 inches a winter at a NOAA weather station 4.8 miles away, averaged over 10 winters. Between December 1 and March 31 that brings 2.9 weekday mornings a year with 2 inches of new snow or more, and 0.7 with 4 inches or more.

7 inches on November 26, 2018, the largest single day at a NOAA weather station 4.8 miles away in 10 winters. The snowiest winter was 2018 to 2019, with 40.8 inches.

It reads the National Weather Service forecast for Iowa City 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 Iowa City’s own big snow morning: 3.6 inches, the top tenth of snowy weekday mornings at a NOAA weather station 4.8 miles away.

Iowa requires at least 180 days or 1,080 hours of instruction, as the board chooses. When a board extends the calendar to make up weather closures, it may excuse seniors who have already met graduation requirements.
