Here is my weekly weather quiz question. What is a “Turkey Tower?” Here is the correct answer. A Turkey Tower is slang for a narrow, individual cloud tower that develops and falls apart rapidly. The sudden development of turkey towers from small cumulus clouds may signify the breaking of a cap. I”ll have a new weekly weather quiz question for you starting Monday. The First person to post the correct answer as a comment will win a week of free personalized weather forecasts tailored to your needs.

THE WEATHER PATTERN:

  •  An Upper Level Low Pressure Trough (Shaded “U” shape with arrows) took over to help bring us some desperately needed rain. The graphics for days 1-3 show the frontal system that pushed through Oregon. The air quality in Eugene was actually in the Good Category at 5PM Saturday. The graphics for days 3-7  Tuesday through next Saturday show the complex frontal system moving through the Pacific Northwest Tuesday. Yet another complex frontal system will be approaching the coast Thursday sliding through Friday, then a warm front is offshore next Saturday.
  • 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 despite the rain.  Please be very careful out there and remember Smokey Bear’s words “Only you can prevent wildfires.”
