The Bay Area’s brief reprieve from the rain Thursday should give way to a series of storms that will douse the region for the next seven days, officials said.

The first storm is expected to approach the area Friday afternoon with moderate rain and will linger through Saturday morning, said Roger Gass, a meteorologist with the National Weather Service.

After showers taper off Saturday afternoon, another storm system will arrive that night and last through Sunday. From there, the light showers will last through next week, Gass said.

“Right now, it doesn’t look like we have any one system that is significantly strong or producing a significant amount of heavy rain,” he said. “But it does look like we will see periods of several systems moving in and bringing light to moderate rainfall to portions of the region.”

Though the Bay Area will be wet, no significant drops in temperature are expected.

San Francisco will remain in the upper 50s throughout the week, and Oakland and the South Bay will see temperatures in the low 60s, officials said.

Since the water year began on Oct. 1, San Francisco has received 7.46 inches of rain, bringing the city to 73 percent of normal rainfall at this time of year (10.15 inches).

Oakland is at 72 percent of its average with 6.6 inches of rain. The North Bay has fared a bit better, with Santa Rosa at 85 percent of average rainfall with 13.73 inches.

“We would expect these systems to bring those numbers up in the coming days,” Gass said. “But at this time we don’t see any kind of really strong rainfall that is going to up those numbers to extreme levels.”

Up to an inch of snow is expected in the Lake Tahoe area, but not much more than that until the middle of next week, said Dawn Johnson, a meteorologist with the National Weather Service.
