THE WEATHER PATTERN:

  •  An Upper Level Low Pressure Trough (Shaded “U” shape with arrows) takes over to help bring us some desperately needed rain. The graphics for days 1-3 show a frontal system just offshore this afternoon, then sliding through. The smoke will start to clear out, but won’t do it all at once. The graphics for days 3-7  Sunday through next Thursday show the complex frontal system past us Sunday and Monday, then moving through the Pacific Northwest Tuesday. Yet another complex frontal system will be approaching the coast next Thursday.
  • Note: The fire danger in Oregon is still in the Extreme category for all of Western Oregon and it is still very dry out there.  Please be very careful out there and remember Smokey Bear’s words “Only you can prevent wildfires.”

The accuracy of any given forecast can change due to unexpected changes in atmospheric conditions, so there are no guarantees that the actual weather will conform to the projected forecast.
