Bay Area residents, like most of the rest of the country, woke up on Friday to chilly — even freezing — temperatures. In fact, in Livermore, temperatures reached a low of 28 degrees, matching a historic low set in 2007, according to the National Weather Service.
No other Bay Area city dropped that low, but temperatures overall were about 7 or so degrees colder than normal because of an Arctic front pushing in from the north, NWS meteorologist Brian Mejia said.
For example, San Francisco was a balmy 39 degrees when it is usually 45 degrees this time of year, Mejia said. (He wore a hat to work.)
And Oakland was 34 degrees when it’s normally 41 degrees, he said.
And in San Jose? The airport reading at 4 a.m. showed the mercury dropping to 32 degrees (yes freezing!) when the normal range is typically 42 degrees.
But South Bay folks should consider themselves lucky, and relatively warm. The historic record for cold in San Jose was 18 degrees set in 1894.
