The cold Gulf of Alaska storm headed for California is forecast to take one of two potential paths: one over land that would be colder and drier & one over sea that would be wetter, bringing big snow to the Sierras.
The wetter, green path could bring 12-18″ of snow to the Sierras. The drier, blue path would bring 4-8″ of snow to the Sierras.
Unfortunately, the drier path is the more likely path.
THERE ARE TWO POTENTIAL SCENARIOS INCLUDING THE MOST LIKELY DRIER INLAND TRACK AND A LESS LIKELY OFFSHORE TRACK THAT WOULD BRING HIGHER SNOW AMOUNTS THE SIERRA. - NOAA Reno, NV today

Temperatures will be cold late week with the potential for a widespread San Joaquin Valley freeze.
