A mass of warm air sat atop the Bay Area on Monday, resulting in some decades-old heat records falling before a gradual cooling trend brings temperatures closer to normal later this week.
A record was set in Mountain View, where temperatures rose to 88 degrees, breaking a previous high of 84 that had stood since 1981. San Francisco International Airport reached 83, besting a previous record that had stood since 1981 by one degree, while Oakland reached 85, three degrees hotter than a record from 1966.
According to meteorologist Austin Cross of the National Weather Service, a "thin wisp of marine air" is making its way up the coast, and temperatures are expected to drop to 77 by Wednesday and 70 on Thursday in San Jose.
Cross said residents can expect clear skies throughout the Bay Area this week.
