A large high pressure center that was centered over the four corners region strengthened on September 4 and brought near record high temperatures to eastern Kern County. The high strengthened further on September 5 and provided the San Jaoquin Valley and the Sierra foothills as well as the Kern County Desert areas with a period of oppressive heat during the Labor Day holiday weekend between September 5 and 7. A low pressure system dropped from western Canada into the Great Basin on September 8 resulting in lowering temperatures across the area as the large high weakened.
