World weather photos: Summer roars along
Western Heat Wave
The sign at the Clovis Memorial District building reads 107 degrees, Friday, Aug. 10, 2012, in Clovis, Calif. Both Friday and Saturday the extreme heat hitting the Central Valley will be closing in on records. Temperatures soared into triple digits across the western United States on Saturday as a continuing heat wave strained energy supplies and sent thousands to beaches, lakes and shopping malls in search of cooler climes.
