Here is my weekly weather quiz question for the last time. What is “SKYWARN?” Here is the correct answer. SKYWARN is a nationwide network of volunteer weather spotters who report to and are trained by the National Weather Service. These spotters report many forms of significant or severe weather such as Severe Thunderstorms, Tornadoes, Hail, Heavy Snow, or Flooding. Contact your local National Weather Service Forecast Office to learn about SKYWARN activities in your area. 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. 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.

An upper level low (Shaded “U” shape with blue arrows) returned and pushed a frontal system through the Pacific Northwest, thus returning our rain chances. Over the weekend another weak frontal system should move in. It looks like there will be a dry spell for a while next week until a frontal system shows up next Friday.
