Sorry, but no winner this week. Here is my weekly weather quiz question for the last time. Can a bolt of lightning appear in any other color that white? Here is the correct answer. Yes, lightning can appear to be many different colors depending on what the light travels through to get to your eyes. In snowstorms, where is somewhat rare, pink and green are often described as colors of lightning. Haze, dust, moisture, raindrops and any other particles in the atmosphere will affect the color by absorbing or diffracting a portion of the white light of lightning. I’ll have a new weekly weather quiz question for you starting Tuesday (instead of the usual Monday) due the the holiday today. 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.

Advisories: NOT AT THIS TIME.

An upper level low (“U” shape in blue arrows shaded in grey) is moving eastward away from Oregon. A weak frontal system moved through Oregon, but fell apart as it slid eastward with not much effect once again. A high pressure ridge (“Arch” shape in blue arrows offshore) will warm us up a bit this week just in time for the kids to go back to school. A more serious cold front will move through the Pacific Northwest on Sunday giving us a chance of rain.
