Alan Fegley, superintendent of the Phoenixville Area School District, says in a letter to parents that Wednesday's decision to call off school was made late because the snow wasn't originally forecast to arrive until after noon.
The letter was obtained by The Mercury newspaper of Pottstown.
He says the decision was made in time for elementary students, but that it came after many middle and high school students were already at school or on their way.
He says 87 buses had to be redirected to take students back home, including many students who had already been dropped off.
