Here is my weekly weather quiz question. 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) will be moving across Oregon. Will we will see a change in our weather pattern over next weekend? It is too soon to get too excited about it until there is some hard evidence it is possible. Add in the fact that there is a chance another low pressure trough will be enhanced by the remnants of a Pacific system and produce clouds and showers for the weekend. A new frontal system aims at the Pacific Northwest on Saturday moving in by Sunday. That could put a “damper” on the possible sunshine and warmer weather for part of the weekend into next week.
