ABC7 News Meteorologist Mike Nicco says temperatures will be 10 to 15 degrees, maybe even 20, above average everywhere except the Coast.

That will increase our risk of heat-related illnesses Thursday, Friday and Saturday.

But there is relief on the way. There is a 33 percent chance of temperatures below average for the first couple of days next week before the heat returns.

A Spare the Air Alert is also in effect for the Bay Area through Friday.
