This is your last day chance to answer my weekly weather quiz question for this week. Who worked on mathematical models for weather prediction providing the basis for the first successful numerical (computer) forecasting models? He is also credited with predicting the existence of jet streams and developing the main theories describing their behavior. 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: NONE AT THIS TIME.

An upper level trough of low pressure (“U” shape) is moving across the Pacific Northwest and has spread some showers mainly from the Northern third of Oregon North into Washington. Behind it will be a high pressure ridge (“arch” shape) over the weekend that should dry us out for a while at least, but another trough will follow closely behind the ridge trying to bring the clouds back. A new frontal system aims at the Pacific Northwest on Saturday but at this time it looks like it will fall apart before it makes landfall late in the weekend. Will it bring just clouds or will we get more showers? The best chance for showers will be in the Cascades starting Monday.
