Parts of Milwaukee were under water this morning in the wake of the record-drowning 6 inches of rain that fell yesterday. The dividing line between warmth to the north and heat to the south will shift northward into southern New England tomorrow then move back southward on Sunday night. By Monday morning, the latest heat wave will be history from Chicago to New York City and Philadelphia. The video has more:
