A pattern change will allow California to cool off a bit, but also cause drenching storms to erupt over the interior West. On Sunday, temperatures soared to near-record levels above 100 F across California’s interior. However, the record-challenging heat will subside early this week. An area of high pressure shifting eastward will gradually cause temperatures to drop across interior California and then the remainder of the Southwest. “The first to feel these changes will be California, when temperatures will start trending down on Monday,” said AccuWeather Long-Range Meteorologist Max Vido.
