Here is my new weekly weather quiz question. Here it is. What is “AFOS” and why is it being replaced by “AWIPS?” 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) has strengthened a bit,re-growing its hump, keeping the rain away longer than expected. An upper level trough of low pressure (Shaded “U” shape) behind the ridge is pushing to position itself along the coast to return the rain chances. A cold front will approach the Pacific Northwest and push in Saturday increasing the chances for rain.

Advisories: NONE AT THIS TIME.
