California’s Central Valley will have another round of searing temperatures that will boost energy demand this week, reaching a high of 103F (39C) in Sacramento on Tuesday.
A heat advisory is in place for the state capital through Wednesday night, the National Weather Service said. The region’s worst conditions will be north of Interstate 80, which passes east to west across the state, said Eric Kurth, a weather service meteorologist in Sacramento.
“It is unusually hot for this time of year,” Kurth said by telephone. “We had a significant heat event last week, but this one doesn’t look quite as strong.”
High temperatures boost air conditioner use, driving up energy demand that can impact the electric grid. In recent years blistering temperatures have caused disruptions in the delivery of electricity in California, as well as in Texas and across parts of Mexico.
Kurth said an early ridge of Pacific high pressure is helping drive temperatures upward, but that will lose some of its potency later in the week. Also helping the situation will be cool breezes coming off San Francisco Bay.
Known locally as a “delta breeze” the cooler air will be enough to take the edge off the worst heat across Sacramento, Kurth said.
