Sorry, but no winner this week. Here is my weekly weather quiz question for the last time. What is the “green sky” effect? Here is the correct answer. During severe thunderstorms, a definite green tint in the dark clouds is often a sign of nearby hail and possibly even tornadoes. A satisfactory explanation for this effect has yet to be agreed upon by meteorologists. Some believe it may be due to optical effects caused by the large amounts of ice suspended aloft in the storm’s powerful updraft. I’ll have a new weekly weather quiz question starting next Monday. Please 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.

A trough of low pressure is sliding to the East and weak high pressure will be try to take over before another low pressure trough slides down from the Gulf of Alaska. It looks like we’ll be seeing lots of clouds mixed with some sunshine, and slight chances of light rain or showers as a couple of little disturbances move through over the weekend, then a frontal system will be approaching Oregon by the end of the weekend and early next week.
