LOS ANGELES (AP) — Rain moved into Southern California Friday afternoon, but only a few sprinkles fell during the funeral for former first lady Nancy Reagan at the Ronald Reagan Presidential Library in Simi Valley.

A waterproof tent behind the library shielded those attending the service.

Minutes after the service ended, the skies unleashed a blustery downpour and mourners pulled out umbrellas as they filed past her coffin.

The National Weather Service said the cold front would move through the region very quickly and peak rain rates would likely only last an hour or two, with a couple of hours of lighter precipitation in its aftermath.

Snow levels were expected to initially be between 6,000 and 6,500 feet, then lower, possibly to 4,500 feet by night.

In Northern California, snow is forecast in the Sierra Nevada throughout the weekend. The Sierra snowpack normally stores about 30 percent of California's water supply.

Several Sonoma County schools closed Friday due to fears that the Russian River would flood, but by afternoon, forecasters had cancelled warnings for major rivers.

Still, the Russian River was running high and fast Friday with vineyards submerged and streets closed. At a trailer park in Forestville mere feet from the river, a resident was moving his dog and trailer to drier land.

National Weather Service forecaster Bob Benjamin said the San Francisco Bay Area will stay mostly dry Saturday with another system possibly moving in by evening. A flash flood watch remains in the north bay.

Another storm is expected Sunday.
