Even veteran meteorologists expressed amazement at the scorching temperatures.
"Tons of records were smashed, and not just in the interior part of the state," said Basil Newmerzhycky, a meteorologist with the National Weather Service.
Mike Pechner, a consulting meteorologist based in Cordelia, said Saturday and today should set state temperature records not just for their dates but for the entire month of July.
"This is the hottest weather we've seen in California in at least a decade or more," he said.
Vallejo reached 111 degrees Saturday, which Newmerzhycky called "unfathomable."
"It is very, very rare for Vallejo to hit even 100, let alone 111," he said. "When all is said and done, this could be the worst heat wave ever for the Central Valley."
Newmerzhycky said the Sacramento record for consecutive days exceeding 100 degrees is nine, and the city has now posted seven straight days of such temperatures.
"We're not going to see any relief at all until Tuesday or Wednesday, if then," he said.

In 1902, only one year after Willis Haviland Carrier graduated from Cornell University with a Masters in Engineering, the first air (temperature and humidity) conditioning was in operation, making one Brooklyn printing plant owner very happy. Fluctuations in heat and humidity in his plant had caused the dimensions of the printing paper to keep altering slightly, enough to ensure a misalignment of the colored inks. The new air conditioning machine created a stable environment and aligned four-color printing became possible. All thanks to the new employee at the Buffalo Forge Company, who started on a salary of only $10.00 per week.
Carrier said he received his 'flash of genius' while waiting for a train. It was a foggy night and he was going over in his mind the problem of temperature and humidity control. By the time the train arrived, Carrier had an understanding of the relationship between temperature, humidity and dew point.
