Scorching temperatures will reign across much of the Bay Area beginning Wednesday, with temperatures expected reach the 90s and 100s in some locations.
The National Weather Service on Monday issued a heat advisory from 11 a.m. Wednesday through 9 p.m. Friday for the North Bay interior valleys, Santa Cruz Mountains and Santa Clara Valley, including San Jose and Hollister Valley. Temperatures are expected between 94 to 99 degrees.
An excessive heat warning — which predicts temperatures between 98 to 108 — is in effect from 11 a.m. Thursday through 9 p.m. Friday for many of the same areas, including in the North Bay mountains, East Bay valleys and mountains, Santa Lucia Mountains, Los Padres National Forest, mountains of San Benito County and interior Monterey County including Pinnacles National Park.
The forecast is that the hottest day of the week will be Thursday. Overnight temperatures aren’t expected to offer much relief, with lows expected to stay in the upper-50s to upper-60s range.
While temperatures are expected to decrease slightly on Friday, they will still be hot.

The weather service shared this advice for the public: “Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.”
With the lingering heat and dry conditions, the weather service is also warning of increased fire danger.
“Onshore flow will be moderately strong on Wednesday resulting in gusty winds near the coast and any interior gaps or passes,” according to Weather Service officials. “Hot, dry and potentially gusty winds would allow fires to spread.”
