Another low pressure trough is now moving onto the west coast.  This system will spread showers and possible thunderstorms across northern California today.   Snow levels will lower to 2500 to 3000 feet north and 3000 to 3500 feet south (Plumas co).  The showers will end over the area tonight as this system heads east.  Monday will have partly cloudy to cloudy skies with maybe an isolated light shower over the mountains.  The next series of storms will start early Tuesday.  The first system will bring moderate to heavy precipitation to the area Tuesday with snow levels rising to 4000 to 5000 feet.  This system will be followed by a colder but not as wet system that will move into the area Wednesday.  This low pressure trough (storm) will be coming out of the north and will lower snow levels to 1500 feet in the north and 2500 feet in the south.    The map below for Thursday shows that the low is now to the east of us over the Great Basin, but the jetstream is now running from north to south over our area.  This strong northerly flow will bring very cold air into northern California.  Minimum temperatures could drop into the mid and upper 20s in the Sacramento Valley Thursday and Friday night.  It now looks like another storm system will be approaching the coast on New Years Day, with the cold airmass in place over northern California we could see very low snow levels with this storm system….
