The transition from a rainy week in the Bay Area to a sunny weekend moved gradually on Friday, with the precipitation from the final of three storms taking its time moving out of area.

Occasional pockets of rain still fell into the afternoon in the Peninsula area of the region, as well as along areas of the central coast, according to the National Weather Service. More rain still was possible into the later afternoon but was likely to be finished before the sun sets, the weather service said.

“It’s just the pace of the storm,” NWS meteorologist Roger Gass said Friday. “There is still moisture aloft. Once the dryer air comes in from the north, we’re going to go dry.”

Once the final drop fell — as it did before the afternoon arrived Friday in areas of the South Bay, East Bay and North Bay — the curtain opened to ever-brightening skies.

The sunny weather is expected to last through the weekend and into early next week. Temperatures will be cold — the highs aren’t expected to climb out of the mid-50s, and the lows will in the 30s and possibly below 32 degrees in some areas, the weather service said.

The agency issued a frost advisory and freeze warning for this morning that runs from Cloverdale to south of Big Sur and as far east as Concord and Livermore. Gass said more advisories may be likely as the cold snap continues.

Still, the cold weather also will be quite calm. Winds that gusted as high as 50 mph in the upper elevations Thursday and higher than 65 mph on Tuesday had calmed by Friday morning, and flood advisories that dotted the region expired.

The dry weather also is expected to provide a small bit of relief for soil that is fully saturated and prone to run-off. Such conditions contribute to flooding and can bring down trees in rainy weather.

The last of the steady rain fell with moderate pace on Thursday, as it did during the first of three systems that rolled in Jan. 31. The first measurable rain in the South Bay and East Bay since Jan. 3 left an estimated 8 inches of rain in Woodside, 7¾ inches in Saratoga and just shy of 6 inches in Palo Alto through 9 a.m. Friday, according to the weather service.

In that same period, Mount Diablo received an estimated 7.8 inches, Tilden Park 7¼ inches, Richmond 7 inches, Orinda 5¾ inches and Concord about 2 inches. Nearly 4 inches fell in Oakland.

The most rain in the area fell atop Mount Tamalpias, which was soaked with an estimated 19 inches by 9 a.m. Friday. Kentfield received about 12 inches, and San Anselmo 10¼ inches. In the Santa Cruz Mountains, Empire Grade received more than 11 inches and Mount Umunhum about 9½.

Those figures were estimates and not yet official, pending a quality-check for accuracy by the NWS. Gass said the weather service likely would release official cumulative totals later Friday afternoon after all of the rain in the area had stopped.

As for the next storm, the weather service said it is forming over the ocean and that its characteristics should come into focus as it moves closer to land. Gass said the soonest rain is likely to fall again is Wednesday.
