A record-smashing heat wave broiled the U.S. East for another day Wednesday, even as thermometers were forecast to soon plunge by as many as 30 degrees in the same areas.
The day's heat wasn't expected to be as intense as Tuesday, when at least 50 heat records were matched or broken and 21 places hit triple-digit temperatures. About 127 million Americans remained under National Weather Service heat advisories, down from the previous day. Sizzling temperatures sent utilities scrambling to keep the air conditioning and lights on amid massive demand for power.
