Here is my weekly weather quiz question. We have all heard the word “Eureka” used when someone makes an unexpected discovery. The question is who in history is quoted shouting “Eureka” when he made a discovery and what was the discovery? Please remember to post your answer as a comment by clicking on “no comments /comments” in the upper right hand portion of this page under the caption, then add your comment. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count. Good luck.

A trough of low pressure (“U” shape on the yellow line) is moving eastward toward us as a high pressure ridge (“Arch” shape on the yellow line) that has been over us slides eastward. A frontal system is pushing through Oregon. The air mass is cold behind it so the snow levels will fall behind it. Another frontal system (position shown is Friday) and one behind it will continue the threat of rain from Friday night through the weekend.
