Whoops. Haverhill Public Schools apologized to families for holding school on Tuesday after the city got nine inches of snow, according to a Facebook post from the district.

The school said it was following weather forecasts, which predicted snow wouldn’t start until 1 p.m. It started mid-morning instead.“We called this one wrong, and we are so sorry!” their post reads.
