While there’s a high chance for thunderstorms in the Sierra Nevada, the probability in the San Francisco Bay Area is slight though the risk is high, the National Weather Service said.
Are thunderstorms common in San Francisco?
San Francisco experiences thunderstorms rarely (not “never”) because the temperatures near the surface offshore are cooled by the upwelling of cold water in the ocean. This results in a stable layer near the surface most of the time, and that stable layer inhibits thunderstorm development.
How often are there thunderstorms in SF?

Why are thunderstorms less common in California?
California (or parts of it) may have moist air, but not as warm. There are more hills, valleys, and mountains which may interfere with low pressure systems and prevent strong thunderstorms from forming, and the Pacific is typically cooler than the Gulf around Florida, which also limits the number of storms.
Which country has most thunderstorms?

What causes dry thunderstorms?
Dry thunderstorms are generated when enough moisture from the Gulfs of Mexico and California is drawn over an area to form stormy clouds at high levels of the atmosphere. But because the air below the clouds is still dry, most of the rain that falls evaporates before it can quench the parched landscape below.
What do thunderstorms mean?
