Heat continued Sunday to scorch the mid-Atlantic and the densely populated region from Washington, D.C., to New York, where the National Weather Service ranked the heat risk as “extreme” when accounting for the high temperatures and their unseasonably early arrival.
Daily temperature records — some more than a century old — continued to fall. In Philadelphia, a reading of 98 degrees beat the record, 97, set in 1888. The high of 101 degrees in Reading, Pennsylvania, also beat the record, which had been set in 1908 at 96 degrees. It was also the first time that Reading had experienced triple-digit temperatures since July 2012.
The Washington area had record-breaking temperatures two days in a row. On Saturday, Baltimore’s high of 101 degrees broke the record of 100 set in 1988, and Sunday, an afternoon recording of 98 surpassed the 97-degree record for the day, set in 2010. In Dulles, Virginia, the temperatures of 100 degrees Saturday and 98 Sunday beat records set in 1988. And in Arlington, Virginia, a 99-degree reading Sunday surpassed the city’s 1988 record.
In Trenton, New Jersey, the temperature reached 98 degrees Sunday. The heat prompted officials in parts of the state, including Pennsville Township, Moorestown, Vineland, Ridgewood, Denville and Butler to announce mandatory or optional water restrictions, asking residents to refrain from washing their cars or watering their lawns.
But the end of the heat wave that gripped much of the United States over the past week is in sight. The weather service predicts that the heat wave will begin to subside early this week.
Relief has begun to arrive in other parts of the country that were hit hard last week, signaling a dip in the heat that’s still gripping the mid-Atlantic. In New England, record-breaking temperatures have already receded, and Sunday brought lower temperatures to the Ohio Valley and the Midwest.
In Detroit, the heat index fell from a high of 95 degrees Saturday to 87 degrees by midday Sunday, a more normal level for this time of year. In Cleveland, the heat index fell from a high of 97 degrees Saturday to 83.
