Q: How does the Brown Deer snow day predictor work?

It reads the National Weather Service forecast for Brown Deer 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 Brown Deer’s own big snow morning: 3.9 inches, the top tenth of snowy weekday mornings at a NOAA weather station 1.2 miles away.

Q: Can Wisconsin schools hold a remote day instead?

If a district offers make-up instruction virtually on a weather closure, those hours can count; the rule sets no cap on such days.
