For Bay Area, a more traditional rain is on the weather menu

""We've got low pressure from the Gulf of Alaska moving on down," NWS meteorologist Brayden Murdock said Monday. "One will come through, and we'll get rain. We'll get a pause. Then we'll get the second one. The main rain bands hit up close to the North Bay and then will spread across the Bay Area. . . . It's a pretty typical winter set-up.""

"That it's happening just as the region settles into autumn is not unusual, Murdock said. It's simply an indication that the weather pattern has cleared itself of the tropical influence that brought hundreds of lightning strikes amid muggy, warm temperatures and isolated storm cells last week that dumped brief outbursts of heavy rain."

"A bit of rain ahead of that first storm front early Monday carried tiny warmth left over from those tropical conditions, but low pressure coming from the Pacific Northwest was expected to be colder and the second front behind that one even colder, Murdock said. As a result, this rain will be far more steady and less isolated, as well as considerably less intense."

Remnants of a tropical storm have passed, and two traditional Pacific low-pressure systems will bring steadier, lighter rain to the Bay Area beginning Monday. The first front will arrive late Monday morning or early afternoon and persist into Tuesday, followed by a temporary pause and additional scattered showers Tuesday evening into Wednesday. Rainfall totals are modest, with the heaviest accumulation near Mount Tamalpais (around an inch) and parts of Sonoma County receiving roughly a half-inch between the two systems. Temperatures will trend cooler as the second front arrives, and isolated thunderstorms remain possible in some northern areas.
