In the Bay Area, conditions will not be quite as favorable as in the Central Valley, but while precipitation will probably start out as rain under 2000 feet snow levels will drop quickly on the back end of the precipitation band associated with the cold front, possibly bringing some snow accumulations down to 1000 feet and a brief rain / snow mix to even lower elevations.
This snowpack accumulation near the poles, which gets its water via the Arctic and Antarctic oceans, that in turn rob it from equatorial latitudes of our oceans, also results in a reduction in the earth's spin axis moment of inertia and causes the spin rate to increase as evidenced in the recent history of the rate at which Leap Seconds are added to our calendar (see Wysmuller's Toucan Equation for more on this evidence that during this warm time with much greater polar humidity, earlier seasonal, later seasonal and heavier snows are beginning to move water vapor from the oceans to the poles to re-build the polar ice caps and lead us into a global cooling, while man - made CO2 continues to increase http://www.colderside.com/faq.htm).

Scientists: Warming causes Antarctic ice sheet growth, and lower sea levels By Kenneth Richard While many scientists are projecting rapid sea level rise as a result of a warmer Antarctica and consequent ice sheet melting, other scientists are projecting that the surface of the Antarctic ice sheet will gain in mass because a warmer Antarctica means snow and ice accumulation will outpace the -LSB-...]
As warmer air can hold more moisture, it is possible that increasing snow accumulation compensates part of the sea level rise.

That all changed with the Supreme Judicial Court's 2010 decision, Papadopoulos v. Target Corp., in which the court abolished any legal distinction between natural and unnatural accumulations of snow and instead said that a property owner has a duty to act «as a reasonable person under all the circumstances» with regard to removal of snow and ice.
Because our existing case law holds that a property owner does not violate the duty of reasonable care by failing to remove natural accumulations of snow and ice, see Sullivan v. Brookline, 416 Mass. 825, 827 (1994), the judge concluded that, as a matter of law, the plaintiff could not prevail on his claims of negligence; therefore, the judge allowed the defendants» motions for summary judgment.
Placing different obligations for snow removal on different kinds of properties (e.g., businesses and small homes) is entirely sensible and is part of a larger historical trend recognizing that liability for landowners should not hinge on hard - and - fast legal rules (such as the «natural accumulation rule») but instead should depend upon the purposes for which the property is used.
