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 next Tuesday (instead of the usual Monday) due the the holiday. 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 across Oregon. That will keep rest of the long Labor Day Holiday weekend really nice. The temperatures won’t be summer hot, but rather average for the time of the year, but it will be dry. A weak frontal system will try to move through Oregon Monday, mainly to our north, with not much effect once again. A high pressure ridge will warm us up next week just in time for the kids to go back to school.
