The upper level airflow from over the Pacific Ocean is pumping moisture into the Pacific Northwest.  The next frontal system is moving through Oregon and bringing us some heavy rain. A second  frontal system (shown: position on Friday) will move in and if we are lucky, after its passage,  it might be drier over the end of the weekend, with maybe a slight chance of sprinkles on Sunday.

Advisories: NONE AT THIS TIME.
