Temperatures topped 100 degrees fahrenheit across the Western United States on Saturday, testing even cities accustomed to high heat.
Many states experienced temperatures 10 degrees above normal for this time of year, in a summer shaping up to be one of the hottest on record. July alone was the hottest month recorded in the United States since 1895, said the National Oceanic and Atmospheric Administration.
Fifty-five percent of the U.S. is experiencing at least moderate drought conditions. Extreme heat is now covering 13 percent of the planet, according to a new study, a drastic increase from less than 1 percent in the years before 1980.
The Associated Press reports that the homeless population of Phoenix, Ariz., flocked to the city's shelters, which opened up a number of extra beds to accomodate the increase. Temperatures there hit 116 on Wednesday, Aug. 8.
National Weather Service forecasts a high of 98 degrees on Monday, Aug. 13, in the Treasure Valley. However those temperatures are expected to drop through Thursday, Aug. 16. A high of 89 degrees is expected, with a low of 61.
