The Northstate will see high and mid level clouds move through today.  A cold but weak system will arrive by tomorrow evening.

High level clouds will likely slow the valley down by a degree or two compared to yesterday afternoon.  

A low pressure system will slide just south of the Northstate Wednesday night into Thursday morning.  We'll still see enough moisture to put down a few quick inches for some elevation above 3,000 ft.  forecast profiles even support snow as low as 1,500 ft by Thursday morning.  Though there is not a lot of moisture to work with the cold air-mass will likely support ratios  15+"- 1", down to 2,000 ft.  So that'll help add to accumulations.

 Models are even showing another clipper system coming in by early Friday morning that could give another inch or two down to 2,500 ft.

Unfortunately all this low snow will probably be lost fairly quickly by this weekend, because it will get rained on.  Though so cold air may be  trapped at low elevations Saturday morning, allowing for some initial low snow.  Warm advection precipitation and mixing will help to clear out that cold air-mass and snow levels will rise dramatically.

By Sunday snow levels should be over 6,000 ft.

The big winners with this "Atmospheric River" event will be south and western facing slopes(as usual) as they'll have help from orographic lift.
