No winner this week. Here is my new weekly weather quiz question for the last time. What is the “Urban Heat Island” effect? The term “heat island effect” describes built up areas that are hotter than nearby rural areas. The annual mean air temperature of a city with 1 million people or more can be 1.8–5.4°F (1–3°C) warmer than its surroundings. In the evening, the difference can be as high as 22°F (12°C). Heat islands can affect communities by increasing summertime peak energy demand, air conditioning costs, air pollution and greenhouse gas emissions, heat-related illness and mortality, and water quality. I’ll have a new weekly weather question for you next 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.

A though of low pressure (“U” shape on the jet stream) is moving eastward toward the Oregon coast. A frontal system is moved through the Pacific Northwest with another disturbance right behind it. Another frontal system will push through Tuesday and you know what that means.. a lot more rain on top of the heavy rains we have already experienced.
