PHILADELPHIA — Americans dipped into the water, went to the movies and rode the subway just to be in air conditioning Saturday for relief from unrelenting heat that has killed 30 people across half the country.
The heat sent temperatures soaring over 100 degrees in several cities, including record highs in Washington, D.C. (105), St. Louis (106) and Indianapolis (104), buckled highways and derailed a Washington-area train even as another round of summer storms threatened.
If people ventured outside to do anything, they did it early. But even then, the heat was stifling.
