The California Weather Blog has an update on the drought and El Niño forecast.
A lot more rain is in the forecast for Northern California over the coming 7-10 days (perhaps more than 10 or even 15 inches in orographically favored parts of the North State, and more than 6 inches in the coastal mountains as far south as the Bay Area). Then, during the final week of January, there is an emerging model ensemble consensus that an burst of jet stream energy from the West Pacific will propagate eastward across the entire basin, forcing the Pacific storm track southward from Northern California and bringing enhanced precipitation to the entire state. Such an active jet pattern makes pinpointing the details nearly impossible more than a few days in advance, but there are early signals of a situation potentially similar to the one we experienced in early January.
Here is a assessment of current drought conditions:
