Here is my weekly weather quiz question for the last time. What is an “Observation Well?” Here is the correct answer. An Observation Well, in hydrologic terms, is a non-pumping well used for observing the elevation of the water table or piezometric surface. I’ll have a new weekly weather quiz question for you starting Monday. 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.

An upper level ridge of high pressure (Shaded “Arch” shape with blue arrows) took over to keep the rain away from us, but that will soon change.  Some fairly weak storms will add clouds and showers to the mix. A new frontal system is poised to move in which will bring the chance of rain back. Here is another frontal system shown moving toward Oregon Friday morning which means more showery weather. Sunday will see yet another frontal system setting up to move into the Pacific Northwest.
