Temperatures spiked to 112 degrees on Monday in Stockton and Paso Robles. In Sacramento, the mercury shimmered at 114 degrees. In Livermore and Fairfield, it was 116 degrees, shattering records. In Death Valley, it was a blinding 121 degrees.
As a huge heat dome settled over the West just in time for Labor Day weekend, temperatures soared across California, fueling wildfires in Siskiyou County near the Oregon border and baking Southern California to the point that, in some parts of the high desert, the skies violently opened, unleashing freak, monsoon-like rain.
Meteorologists predict the blistering heat will be with us for the rest of the week. In a news conference on Monday, the state authorities thanked Californians for conserving power, saying their efforts had lowered energy use by as much as 2 percent below forecasts.
That was the good news.
The bad news was that all of that midnight laundry and off-peak electric car charging has not been enough to forestall the possibility of blackouts.
“We have now entered the most intense phase of this heat wave,” said Elliot Mainzer, the chief executive of the California Independent System Operator, which oversees the grid. “We need two to three times as much conservation as we’ve been experiencing to keep the power on.”
Specifically, the state energy authorities are asking Californians to significantly reduce power consumption, particularly between 4 p.m. and 9 p.m.
During the day, California’s grid runs mostly on solar power, natural gas and power imported from other states as needed. But solar power supplies tend to decline later in the day, the state’s natural gas plants are aging and drought has constricted the availability of hydropower. Meanwhile, the heat wave is keeping nighttime temperatures high, too.
With temperatures again forecast to rise toward record territory in most inland parts of the state, Mainzer warned that rolling outages could be a possibility if consumers don’t “step up” and conserve. Alice Reynolds, president of the California Public Utilities Commission, encouraged Californians to “pre-cool” their homes in the morning by letting in cool air, lowering indoor temperatures to 70 degrees or so until 4 p.m., and then raising thermostats to 78 degrees in the late afternoon during the peak usage period.
Other requests: Avoid using large appliances; turn off unnecessary lights; and charge phones, laptops and electric vehicles before peak hours. Also stay hydrated and keep an eye on your elderly neighbors.
“It’s not over,” Dr. Tomás Aragón, the state public health officer, said on Monday. “We have a few more days. It’s going to be tough.”

And before you go, some good news
On their very first date, at a Manhattan wine bar in May 2016, a waiter mistakenly referred to Michael Angelo McMillan II as Caroline Benning Hubbard’s husband.
“I didn’t have any rings or anything that would indicate that we were married,” Hubbard said, but “the chemistry that we had just sort of indicated we looked like we were a married couple.”
It wasn’t just the waiter who noticed their connection. A man sitting next to them leaned over to tell them they were a beautiful couple, and asked how long they had been together.
“And we were like, this is actually our first date,” McMillan said.
McMillan and Hubbard had met in San Francisco a month earlier, when they were both on spring break from college and in the city to attend the same conference. They also learned then that they already had friends in common.
“He just seemed so genuine, I just wanted to get to know him,” Hubbard, 27, said.
“It was very serendipitous,” said McMillan, also 27.
The two were married last month. Read more of their love story in The Times.
