Heat Wave Could Break Sunday

The scorching weather that has been blamed in 30 deaths across the United States could break late on Sunday, forecasters say. Some areas could see a dip in the mercury from 100-degree temperatures down into the 90s—a relief in many areas after a heat wave had Americans wiping their brows and cranking up the air conditioning across the country. A wave of cooler weather is expected to move across the eastern part of the country, easing temperatures down in the high 80s in areas like Philadelphia and Washington, D.C., which saw temperatures over 100 degrees Saturday.
