Here is my weekly weather quiz question for the last time. What is a “Gust Front?” Here is the correct answer. A Gust Front is the leading edge of gusty surface winds from thunderstorm downdrafts; sometimes associated with a shelf cloud or roll cloud. See also gustnado or outflow boundary. 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.

A blocking Upper Level High Pressure Ridge (Shaded “arch” shape with arrows) continues to bring sunshine with mild daytime temperatures, but cold enough at night for some patchy frost and fog. The graphics for days 3-7 show no frontal systems approaching the Pacific Northwest for the week as the blocking high pressure continues to remain over us.
Note: Due to the continued fire danger, the outdoor burning season has been delayed until October 20th. The next update on the burning season will be issued at 7 pm October 19th. Remember, burning is always prohibited within the city of Eugene.
