The Snapshot:  Light scattered rain/snow showers with glimpses of the sun or moon will continue through tomorrow.  A nice looking snow producing storm is tracking toward the PNW on Friday.

The Science:  An unstable atmosphere will keep soggy condition occurring in the mountains through tomorrow. High pressure aloft will provide some clearing to occur as well.   A low pressure system sliding down the Canadian coast will bring much lower freezing levels and snow to the mountains on Friday.  Storm totals for this system currently range between .75”-+1” of water or 8”-12” of snow by noon Saturday.   Winds are in favor for Convergence Zone development which could send these amounts higher.  Stay tuned.
