It remains to be seen how hot it may get in parts of San Francisco as temperatures rise all over the Bay Area in the coming days. But Livermore is looking at possibly breaking a 67-year-old heat record on Friday, when it's predicted to hit a high temp of 115 degrees — what is this Death Valley?

As the Chronicle reports via the National Weather Service, the inland Bay Area will be seeing "oppressive" temperatures well in the 100s, and San Francisco, Oakland, and San Jose are all expected to see highs in the 90s on Friday.

The Weather Channel/iPhone Weather app is pegging Saturday as a pretty solid beach day as well as this area of high pressure off the coast should continue to keep the fog at bay — but be sure to check Fog Today just to be sure.

The heat wave this weekend is even keeping some Red Cross workers who were planning to head to help with Hurricane Harvey relief efforts sticking near home, due to the potential for wildfires, as one Red Cross rep tells the Chron.

The NWS has already issued a heat advisory for parts of the North and East Bay for Thursday, and an "excessive heat warning" for Big Sur and areas south and east of Monterey.

Forecasters are warning of rip currents at the coast, so be cautious in trying to cool off at the ocean.

CBS 5's Roberta Gonzales is showing highs of 80 at the coast both tomorrow and Saturday, with clouds moving in and things starting to cool off by Sunday and Monday, though it will remain very hot inland.

So, stick near the coast if you don't want heatstroke, and stay hydrated, everybody! And welcome to the beginning of Indian Summer.
