No winner this week. Here is my weekly weather quiz question for the last time. What does the acronym “NESDIS” represent? Here is the correct answer. NESDIS is the National Environmental Satellite, Data, and Information Service. NESDIS collects, processes, stores, analyzes, and disseminates various types of hydrologic, meteorologic, and oceanic data. NESDIS is also responsible for the development of analytical and descriptive products so as to meet the needs of its users. 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.

A weak upper level low (Shaded “U” shape with blue arrows) is moving away from us as weak high pressure (Shaded “Arch” shape with blue arrows) starts to take over.  That means plenty of sunshine and mild temperatures until another low pressure trough approaches the coast returning the chance of rain by Monday night.
