SAN FRANCISCO (KPIX 5) – A heat wave smothering the West Coast is rewriting the record books, and more record high temperatures were certainly possible for the Bay Area this week.
What makes this current heat wave so uncommon, is the duration. Monday was the fifth-consecutive triple-digit temperature day in the inland Bay Area, away from the water, KPIX 5 chief meteorologist Paul Deanno observed.

- Cal ISO Issues Flex Alert, Urges Reduced Electricity Use
National Weather Service data showed dozens of 100+ highs were set across the Bay Area Monday, including: Cloverdale 105, Concord 105, Napa 105, Livermore 104, Deer Park 104, Pleasanton 103, Windsor 103, Dublin 102, Walnut Creek 102, Calistoga 101, Lafayette 101, Antioch 101, Alamo 101, Gilroy 101, Pleasant Hill 101, Morgan Hill 101, Pittsburg 100, San Ramon 100, Brentwood 100, San Martin 100 and Healdsburg 100.
An excessive heat warning was in effect for the region through at least 7 p.m. Wednesday, but Deanno said Tuesday could actually prove to be the hottest day of the heat wave.
As a result, the California Independent System Operator (Cal-ISO) issued a Flex Alert for Northern California on Tuesday, asking utility customers to reduce their energy use because of anticipated high demand between noon and 7 p.m., when scorching temperatures will result in the increased use of air conditioners.
For Tuesday, Livermore is again expected to be one of the hottest spots in Bay Area, but parts of the South Bay including Gilroy and Morgan Hill are also poised to reach the triple digits once more. Hot zones will also include other cities in the Tri-Valley, as well as much of Napa and Sonoma counties.
A regional cool-off is not expected until Friday, when Inland highs are forecast to fall into the 90s. That means the Fourth of July holiday will still be very warm and thus, fog is unlikely to obstruct views of fireworks shows in San Francisco and elsewhere.

For those wishing to escape the scorching heat, you may want to head to the beach. Deanno noted that cooler temperatures come as you get closer to the coast, pointing out a 40-plus degree temperature swing on Monday between Pacifica and Danville.
