Field notes
The page says its model weighs conditions beyond fresh snowfall, including frozen precipitation from the previous 48 hours and snow or ice left on the ground after a storm. Its published back-test covers 1,345 school days across 20 districts, with each district evaluated using a model that had not seen that district’s data; these are site-reported results, not independently verified in the supplied evidence. A regional table estimates snowfall thresholds for 50% and 80% closure odds.
