_______ _________
An Upper Level Low Pressure Trough (Shaded “U” shape with arrows) moving closer to us is controlling our Fall weather pattern. Much cooler air has moved in from the north. The graphics for days 1-3 show a surface frontal system heading our way for Saturday. The graphics for days 3-7 more disturbances in our future. There is a possibility of some serious rainfall coming to us from Tropical Storm Rosa over Mexico and moisture moving across the Pacific Ocean from two tropical disturbances.
Note: Due to the continued fire danger, the outdoor burning season has been delayed until October 13th. The next update on the burning season will be issued at 7 pm October 12th. Remember, burning is always prohibited within the city of Eugene.
