The first significant snowfall of the seasons is looking more and more likely for the Sierra and Lake Tahoe area as the week wears on.
The National Weather Service in Reno has issued a winter storm watch beginning Thursday afternoon through Friday afternoon.
Snowfall amounts of six to 12 inches are possible at lake level with one to two feet at elevations above seven-thousand feet.
The service says a low pressure system in the Gulf of Alaska will drop down into Northern California on Thursday and then on into Southern California on Friday.
It's expected to bring rain, then snow at the higher elevations beginning Thursday.
As the system passes Thursday night into Friday, the snow will drop to lower elevations and the precipitation will intensify.
Most of the snow is expected from the Carson Pass south to the Mammoth Lakes area.
However, the weather service warns that even a slight change in the path of the storm could mean much more snow to the north as well.
