Bay Area's latest heat to peak Friday before another temperature hike next week
Briefly

The latest Bay Area heat wave is expected to crest Friday, with temperatures likely surpassing 100 degrees, followed by a brief cooldown before another peak on Tuesday, reflecting a 6- to 6 1/2-day oscillation pattern in global weather.
High pressure ridges and low pressure cycles, influenced by the jet stream, have dominated July's weather, leading to historical heat waves. The current high pressure, though weaker, has moderated temperatures during this recurrence.
Heat advisories and air quality alerts remain in effect amid the heat wave, aggravated by smoke from Northern California wildfires. Brentwood and Concord are expected to reach temperatures above 100 degrees.
