Mother's Day Heat Forecast: Summerlike Streak Ahead For The Bay Area

SAN FRANCISCO — Another hot weekend is ahead for the Bay Area, with temperatures poised to reach new highs for the year, and forecasters expect unseasonable warmth will stick around for the foreseeable future.

According to the National Weather Service, Saturday and Sunday will be the hottest of the stretch, when afternoon temps are likely to climb 10 degrees higher than average along the coast and up to 20 degrees hotter than usual for inland areas.

Forecasters have the highest confidence in breaking 90 degrees around the interior North Bay, East Bay, Monterey, and San Benito, with a slight chance a few spots may even hit 95. Concord, Livermore, Napa, San Jose and Santa Rosa are favored to reach 90 degrees by noon Saturday.

While the latest blast of heat may fall short of the record books, the National Weather Service warns much of NorCal will be under a moderate heat risk through Mother's Day.

"Heat in May isn't that uncommon so record temperatures are not expected per se," NWS Bay Area wrote Friday. "However, even without records, persons with outdoor plans should still use caution. Additionally, stay hydrated, take breaks, [and] never leave people or pets in vehicles."

The forecast shows "very subtle cooling" Sunday, shaving off a handful of degrees to make for a more pleasant Mother's Day. The Bay Area should see more significant cooling Monday, but temperatures will remain unusually high for this time of year. Current models show dry weather, sunshine and elevated temperatures sticking around through the extended forecast period.

Longer-term climate outlooks suggest California could catch a break from the heat to finish off the month.
