Nor'easter comes to a close
The snow should be ending by 9-10pm (already tapering). Generally 10-14 inches in Reading, Wyomissing, and around Berks.
In terms of school on Thursday 3/22, given the volume of snow; the duration of the event; the heavy, wet nature of the snow; and the fact that lots of secondary roads haven't even been touched - school is doubtful for tomorrow.
Working against these lingering effects: it's not going to get super cold overnight, and the sun angle should result in rapid melting.
