Story updated Sept. 1 at 3 p.m.: San Francisco broke its highest temperature record of 103 degrees set in 2000 today. On Friday afternoon, the mercury shot up to 106.

A ridge of high pressure over the Pacific Ocean is bringing scorching-hot temperatures typical in Death Valley to the San Francisco Bay Area.

The mercury is expected to skyrocket on Friday and Saturday with highs in the low 90s on the coast and in the 100s in inland areas.

Livermore was forecast to reach a high of 114 degrees Friday, getting close to the all-time record high of 115 hit on Sept. 3, 1950.

In fact, there's a lot of talk about record-breaking heat, and Anna Schneider, a forecaster with the National Weather Service office in Monterey, says we'll likely experience the hottest days of the year over Labor Day weekend.

"We had some heat waves in June and July this year, and a big one June 17-23," Schneider says. "It looks like it's going to be a bit warmer."

Some locations could also break record highs for the same day, and Schneider says, "It's definitely possible" that we break some all-time record highs.

"I don't know for sure," she says, "But I wouldn't be surprised."

For those who like to keep track of these records, we've put together, in the gallery above, a list of highest-ever temperatures recorded at National Weather Service stations around the Bay Area.

Healdsburg wins the prize for the highest temperature in the gallery with a high of 116 on July 13, 1972.

The National Weather Service is predicting this wine country town will hit 109 on Friday and 108 on Saturday — far from the record but when it's that hot outside, it can be difficult to tell the difference.

Temperatures are expected to drop slightly Sunday and the warm weather is forecast into next week.
