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) is still controlling the weather of the Pacific Northwest. A frontal system is on its way to us bringing another wave of showers. Another frontal system adds some moisture for showers continuing Wednesday. An upper level high (Shaded “Arch” shape with blue arrows) tries to dry us our Thursday and Friday, but it looses out to low pressure (Shaded “U” shape with blue arrows) just in time for the Memorial Day Holiday Weekend.
