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 Thursday afternoon. The smoke will start to clear out, but will probably do it slowly since it is trapped in this valley. The graphics for days 3-7  Friday through next Tuesday show the complex frontal system past us Friday. Another front will be moving through the Pacific Northwest next Tuesday.
  • 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.
