It’s Monday and time for a new 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) has moved in along the coast and will keep us alternating between periods of clouds and cooler temperatures, and rain or drizzle and even a thunderstorm thrown in for good measure, then back to less cloudy and slightly warming temperatures until late next week. A frontal system will be approaching the Pacific Northwest by midweek which would indicate the that there seems to be no end to this wet “Springlike” weather pattern soon. We could see a change over next weekend, but it is too soon to get too excited about it until there is some hard evidence it is possible.
