Here is my weekly weather quiz question for the last time. What is “the chromosphere?” Here is the correct answer. The Chromosphere In solar-terrestrial terms, is the layer of the solar atmosphere above the photosphere and beneath the transition region and the corona. 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.

A blocking high pressure ridge (Shaded “Arch” shaped with blue arrows) has settled over the Pacific Northwest. Cold Canadian air has dried us out and given us the coldest temperatures of the season so far, particularly at night. Remember to be careful in the mountains due to the new snowfall and potentially icy driving conditions. A frontal system will be on its way to the Oregon coast Monday bringing back the slight chance of rain by Monday afternoon.
