What, When and Where:
A band of rain that moved through Virginia and eastern Maryland this morning was poised at noon to cause a rainy afternoon and a wet and splashy commute for Philadelphia, New York City and nearby places. After school sports will be affected in a number of localities.
This is more than a passing shower; some places will have at least two hours of rain. The rain will depart from Philadelphia after dark, and New York City by midnight. Some of the rain will affect eastern New England, including Boston, overnight. All places will see an increase in sunshine tomorrow.
