The first serious storm in weeks swept through the North Bay early Wednesday, knocking out power and bringing much-needed rain.

Rainfall at the Charles M. Schulz-Sonoma County Airport early Wednesday totaled 1.34 inches.

In other areas National Weather Service volunteer rain watchers reported 1.29 inches in Cloverdale and 1.6 inches in Monte Rio. In Petaluma .31 inches fell and a Santa Rosa resident recorded .39 inches of rain.

There has been no sustained rainfall since the start of the year other than spits and dribbles, said meteorologist Diana Henderson with the National Weather Service.

Showers are expected in the North Bay through Thursday night.

"It'll be all over by Friday," Henderson said.

The CHP and emergency fire dispatchers early Wednesday reported no serious weather-related problems.

While power outages were reported in the region, details weren't available from PG&E early Wednesday.

The storm pushed into the region mainly after midnight Tuesday with gusting winds and heavy downpours.

At the airport 40 mph winds were recorded.

By 7:30 a.m. the bulk of the storm had moved as far south as Monterey, leaving behind cloudy skies and the promise of cool temperatures and showers.

Morning lows should drop back into the 30s Thursday and Friday, coinciding with a drop in afternoon high temperatures down into the 50s Wednesday and Thursday.

By the weekend the afternoons should warm into the upper 60s with a chance of 70 degrees on Monday.

The next possible chance of rain is Tuesday, she said.
