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.

Governor Brown's mandatory restrictions for residential and commercial water users drew mixed reactions in Fresno.
The governor’s executive order includes stricter reporting requirements for agricultural water users – but no mandatory restrictions, unlike urban areas. To farmers, that’s enough.
California’s cities are subject to 25 percent water reductions under Governor Jerry Brown’s executive order; but those water restrictions don't apply to the biggest users of water.
UPDATED: For the first time ever, a governor of California is imposing mandatory water restrictions. Gov. Jerry Brown issued an executive order Wednesday that mandates a 25 percent cut in urban water use from now through next February.
