The relentless heat wave baking the Bay Area and Northern California, originally expected to peak on Tuesday of this week, will last into the weekend, forecasters said Friday.

This weekend the thermometer is expected to soar past 100 degrees in many parts of California, just as it has for much of what has been a record-setting week.

From Santa Rosa in the North Bay to San Jose in the South Bay, same-day temperatures were broken as the mercury soared into the triple digits at the hottest inland locations, while coastal areas got into the 90s under cloudless skies, according to the National Weather Service.
