 Forecasters say a long-running heat wave that's already shattered previous records across the country will persist, making parts of the West with dangerous temperatures that will soar into the 100s. The scorching weather also held the East in its hot, humid grip throughout the week. National Weather Service meteorologist Brian Jackson says the heat records fell over the holiday weekend. Palm Springs, California set their all-time high record temperature of 124 degrees on July 5th. That broke their previous all-time record high of 123.
