Here is my weekly weather quiz question for the last time. What is the “Diablo Wind?” Here is the correct answer. A Diablo Wind is similar to Santa Ana winds in southern California. These winds occur below canyons in the East Bay hills (Diablo range) and in extreme cases can exceed 60 mph. They develop due to high pressure over Nevada and lower pressure along the central California coast. I’ll have a new weekly weather quiz question for you starting Monday. The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs. Good luck.

An Upper Level Low Pressure Trough (Shaded “U” shape with arrows) will continue sending storms into Oregon while weak high pressure clears us out for Monday and at least part of Tuesday. The graphics for days 1-3 show the complex frontal system that is moving though today. The winds weren’t much this AM but thew will increase again through early Sunday. The graphics for days 3-7 show the frontal systems that will move through the Pacific Northwest Tuesday and next Friday.
