The upper level airflow from over the Pacific Ocean is still pumping waves of moisture into the Pacific Northwest.  A weak storm system has moved through the Pacific Northwest. That doesn’t mean a perfect weekend. There will be sunshine on today because of weak high pressure, but it will be short lived. By tonight, you guessed it, the chance of rain will return. That’s why I kept mentioning all week the chance of precipitation would hang around to at least some degree for the weekend. There will be some sunshine early in the week, but by Wednesday a new storm system will be moving through.
