WASHINGTON D.C. — Portions of the Eastern United States are experiencing unusually warm nighttime temperatures during a heat wave that also includes potentially record-breaking daytime highs. Forecasters anticipate temperatures in areas like Washington, D.C., could exceed 100 degrees Fahrenheit as the heat impacts an estimated 90 million Americans from the Midwest to the East Coast. While daytime temperatures remain high, the persistent warmth throughout the night prevents the human body from recovering from the heat exposure of the day, authorities stated. The lack of significant cooling overnight creates continuous stress on physiological systems.
