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 the frontal system that pushed through Oregon. The smoke has started to clear out, but won’t do it all at once. The graphics for days 3-7  Monday through next Friday show the complex frontal system moving through the Pacific Northwest Tuesday. Yet another complex frontal system will be approaching the coast Thursday sliding through next Friday.
  • 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.”

Note: Weather is a constantly changing phenomenon and weather forecasting is a combination of science, experience, and intuition. 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.
