The swelter that has settled in throughout California shows no sign of relenting this week, weather officials said.
Temperatures are expected to soar into the upper 90s throughout the week in much of the lower elevations of western Nevada County, according to forecasts provided by the National Weather Service, Sacramento.
"The temperatures will slowly, very slowly, trend downwards starting Wednesday," said Stefanie Hunter, meteorologist with the National Weather Service, Sacramento.
The slow-cooling trend is expected to continue until Monday, when forecasts call for the extreme heat to break a little, as temperatures may dip below the 90 degree barrier.
Currently, the greater Sacramento area has experienced seven straight days of temperatures exceeding 100 degrees Fahrenheit, Hunter said.
The hot streak is not unprecedented, she said. The record for consecutive days of 100 degree weather is 11, which took place in 2006.
There are many instances of six consecutive days of such weather in the history of the region, including the late 1800s, the 1920s, the 1980s and a couple times this century, Hunter said.
The cause of the recent spate of hot weather is a high pressure system that drifted west, bringing dry conditions with it, Hunter said.
It is the same high pressure system that brought temperatures of 113 degrees to Oklahoma last week.
Compounding the regional heat streak is the relative quiet of the Delta winds.
