Scattered showers — some heavy but brief — were reported Wednesday afternoon in parts of Santa Barbara County.

They were accompanied by some rumbling thunder and lightning, but no significant rainfall, said Rich Thompson, a meteorologist with the National Weather Service in Oxnard.

Most areas that recorded rain measured a tenth of an inch or less.

The showery conditions, unusual for this time of year, are the result of a low-pressure weather system southeast of Catalina Island, which is spinning moist and unstable air into parts of Southern California, including the Central Coast, Thompson said.

“Showers have been moving through very quickly,” he added, “with brief shots of moderate to heavy rain.”

A 30% chance of showers and thunderstorms remained in the forecast for Wednesday night, mainly before 11 p.m.

The pattern is expected to continue for the next day or two, Thompson said, with most of the showers expected in the mountain areas.

Highs temperatures for the next several days should be in the upper-60s, with overnight lows in the mid-50s.
