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.

California state agencies have released a long-term plan for water conservation. The proposal makes permanent some emergency water conservation measures already in place to deal with the state’s drought.
California regulators hear from residents and farmers concerned about a plan to provide more water for threatened fish in the San Joaquin River and its tributaries.
The State Water Project will deliver more water to California cities and farmland in 2017 than it did this year- at least initially.
(AP) - California water agencies that spent more than $350 million in the last two years to pay property owners to rip out lawns are now trying to answer whether the nation's biggest lawn removal experiment was all worth the cost.
Five years of drought exacerbated wildfires across California. Fire and flood agencies say those burned areas now have an increased risk of flash flooding.
