Midweek Heat Wave Bakes Bay Area With Widespread 90s, 100s

The latest summer heat wave to hit the Bay Area has triggered a heat advisory for interior parts of the region through Thursday night, according to weather officials.

The heat advisory — in effect until 8 p.m. Thursday — applies to much of the North Bay, the East Bay valleys, most of the South Bay and the Santa Cruz Mountains, the National Weather Service said. Areas under the advisory could face temperatures between 95 and 106 degrees.

Temperatures across the interior of the region will range from 95 to 107 degrees, according to weather officials.

The heat advisory applies to North Bay and East Bay mountains and valleys, interior Monterey County, Southern Salinas Valley, Santa Clara Valley, and inland cities.

Air quality will be poor as a result of the high temperatures, according to the Bay Area Air Quality Management District, which has issued a 'Spare the Air' alert for Thursday.

Spare the Air alerts are issued when ozone pollution is forecast to reach unhealthy levels.

On Wednesday, Concord sizzled at 106 degrees, the weather service said. Livermore and Gilroy was right behind at 104 degrees. Other spots such as San Jose, Santa Rosa and Napa reached the upper 90s.

The hot weather is expected to linger through the end of the workweek, Hall said. Inland temps are slated to dip back into the upper 80s by the weekend.
