Only a week removed from summer’s last unofficial weekend, the Bay Area’s weather pattern appeared Monday as if it was just going to skip autumn.
“This is a typical winter-time pattern,” National Weather Service meteorologist Dalton Behringer said early Monday of conditions that are expected to bring at least some rain to most areas of the region this week. “You’ve got low pressure coming down from the north, and the North Bay is where you’ll see most of the activity. Then it will move across the region.”

As a result, almost all areas of the Bay Area should see at least a little bit of rain by Wednesday. Some areas of the region will get their first taste of it Monday night, according to the weather service.
“Mainly, it’s just going to be (Monday) night and into the overnight hours,” Behringer said. “We probably also will see some Tuesday afternoon, and maybe some areas Wednesday where it’s going to be scattered.”
The rain is expected to be quite light, Behringer said, with totals that will be measurable in the tenths of inches, if that. The rain is expected to fall heaviest in the North Bay.
By Thursday, the rain will be gone, Behringer said, but the pattern that led to it will stick around. Behringer said that means there will be more thick coastal fog in the mornings, followed by temperatures in the interior East Bay that will peak in the upper 70s.
As far as the chances for a final encore of any intense heat — a rarity during what has been a mild summer — Berhringer said it is unlikely.
“The current weather pattern looks pretty active going forward the next couple of weeks,” he said. “We anticipate more and more moisture will be coming in. We don’t see anything glaring in the short-term that would indicate we’ll get hot again.”
