Sorry, but no winner this week. Here is my weekly weather quiz question for the last time. What is lake-effect snow? Here is the answer. Lake-effect snow is produced during cooler atmospheric conditions when cold winds move across long expanses of warmer lake water, providing energy and picking up water vapor which freezes and is deposited on the leeward shores usually over a relatively narrow area. I’ll have another weekly weather quiz question for you starting next 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.

Advisories: NONE AT THIS TIME.

A frontal system pushed through bringing the slight rain chance back, for a short time though. An area of high pressure (“Arch” shape on yellow line) dried us out a bit Saturday afternoon, but a large upper level low (the next “U” shape on the yellow line) will take over along with a frontal system (position shown offshore) on Sunday that will bring back more chances of rain to the Pacific Northwest. An upper air trough of low pressure (“U” shape on yellow line) will bring back the moisture until high pressure returns Monday afternoon through Wednesday, then it’s back to low pressure and rain again. A REMINDER: We will go back to Standard time NEXT WEEKEND (officially at 2 AM Sunday November 6th).
