The National Weather Service says a significant storm will bring between a quarter and a half-an-inch of rain to the valley and up to 2.5 inches of rain to the Sierra.
David Rowe with the weather service says there will be snow too.
"Probably about a foot to a foot and a half at the ski areas and maybe 2 to 3 inches down to about 4,500 feet," says Rowe.
Rowe says there are also flooding concerns in areas scarred by wildfire last summer -- for example the Rim Fire near Yosemite.
"When you get heavy rainfall intensity in a short amount of time, you tend to get mud and dust and debris left over from the fires last summer that'll accumulate and run downhill," he says.
Rowe says this will be a significant storm, but the region needs a series of these storms to start recovering from the drought. He says the forecast is dry again for the weekend and early next week.
Rowe urges valley commuters to use caution, especially Thursday morning, when the roads are likely to be slick, and says chains will likely be required in the Sierra.

The California Legislature has sent a $1 billion emergency drought aid package to Gov. Jerry Brown. But one of the two measures in the package drew opposition from Republicans.
Californians show deep concern that the state’s drought may be a long-term problem in a new survey by the Public Policy Institute of California.
California Gov. Jerry Brown’s $1 billion drought response legislation is on its way to the Assembly after winning Senate approval Wednesday afternoon.
A little noticed provision of the proposed $1.1 billion drought relief bill could help poor communities.
The drought is creating a new way for cities to make money, including selling treated wastewater for farm irrigation.
