The National Weather Service says a series of wet systems from the northern Pacific Ocean could bring more than an inch of rain to some areas. The precipitation is likely to continue through the weekend.
A winter weather advisory is in effect Wednesday for Lake Tahoe and much of the Sierra's eastern front where up to a foot of snow is expected by Thursday morning.
The National Weather Service says the heaviest snow is expected during the day Wednesday. Between two and four inches of snow is expected at lake level at Tahoe.
Meanwhile, the snowpack atop mountain peaks in California has a new set of eyes to better gauge the amount of spring runoff. NASA has fixed a twin-engine plane with high-tech equipment to make regular snow surveys in the state.
