'Heat Risk': Bay Area Heat Wave Takes Hold For Mother's Day Weekend

SAN FRANCISCO — The Bay Area's first heat wave of the season is getting underway, and forecasters expect temperatures to stay above average in most areas through Mother's Day and beyond.

In a briefing Thursday, the National Weather Service charted a moderate heat risk in the North Bay, East Bay and South Bay through Friday, and minor heat risks regionwide through Saturday.

During that timeframe, forecasters said temperatures would approach 90 degrees across the interior, where temps will run 5 to 15 degrees warmer than average into early next week.

San Francisco should notch its first day in the 80s of the year, while Concord, Cloverdale, Napa and Santa Rosa chase the 90-degree mark.

"Friday is expected to be the warmest day of the week, especially for inland locations," NWS Bay Area said Thursday. "A southerly surge may cool conditions at the coast, but the interior will still warm into the mid-to-upper 80s to lower 90s."

A gusty start to Thursday prompted a wind advisory in the North Bay, but a calmer trend is favored heading into the weekend. Despite the hot and dry stretch, forecasters said fire concerns should be limited by high moisture in fuel sources.

Even as temperatures begin to taper off heading into next week, sunny and pleasant days are poised to hang on throughout the seven-day forecast period. Extended climate outlooks favor unseasonably warm temps across the Golden State deep into May.
