Brace for a dangerously hot weekend in the Bay Area. The cool down everyone is hoping for now won’t come until Monday or Tuesday. An excessive heat warning was extended until tomorrow night in the North Bay interior and coastal ranges, the East Bay, the South Bay and eastern San Mateo County. Forecasters say some spots will hit 108. A heat advisory is also continuing in San Francisco, where it could get up to 87-degrees while areas in the North Bay valleys soar to 95.
