No winner. Here is my weekly weather quiz question one more time. What are “instrument flight rules?” Here is the correct answer. Instrument Flight Rules refers to the general weather conditions pilots can expect at the surface and applies to the weather situations at an airport during which a pilot must use instruments to assist take off and landing. IFR conditions for fixed wing aircraft means the minimum cloud ceiling is greater than 500 feet and less than 1,000 feet and/or visibility is greater than 1 mile and less than 3 miles. 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.

An upper level trough of low pressure (Shaded “U” shape with blue arrows) has taken over bringing even more rain. A frontal system moved through bringing more showers and the threat of afternoon and evening thunderstorms. As the upper level moves eastward we’ll be in for some more showers. Another frontal system will move southward along the California coast Thursday spinning clouds and showers northward at us.
