We're in for a heatwave through at least Thursday this week, but yesterday, Sunday, is looking like it was the peak in terms of temperatures, with records broken in 10 Bay Area cities. San Francisco hit a high of 88, beating out a record for June 18 set in 1993 by two degrees, as KRON 4 reports though various weather apps yesterday showed high temperatures in parts of SF as high as 98. It was cooler along the coast but still a great beach day for many, and ABC 7 spoke to some South Bay residents who came to Crissy Field just to cool off (see video below).
Another record was broken at SFO, where the temp hit 97 Sunday afternoon, and in San Rafael and Livermore the highs were 105 and 106 respectively. San Rafael broke a record of 98 that had been set way back in 1962, beating it by seven degrees.
For many East and South Bay residents, the temperature spike left them with no power Sunday, with power grids strained and some 43,000 residences affected as of 8:30 p.m. according to the Chronicle. Part of Oakland's Jack London Square was effected, per a friend of SFist, as were 5,000 homes and businesses in Livermore, according to ABC 7. For the rest of the week, in fact, PG&E is recommending that people try to conserve power between noon and 7:30 p.m.
Also, people in Berkeley, Oakland, Piedmont, and other parts of the East Bay were surprised to see a rogue thunderstorm last night that began with just heat lightning, and culminated in a brief downpour of rain.
The first storm cell hit around 11 p.m., and another took shape about two hours later, according to the Chronicle.
There is no Spare the Air alert in effect for Monday, but look out throughout the week as there may be another one like there was on Sunday.
