Here is my new weekly weather quiz question. What is a “Mountainado? ”
________________
An Upper Level Low Pressure Trough (“U” shape) keeps our weather pattern stable with normal temperatures. The graphics for days 1-3 show a cold front pushing through the Pacific Northwest Wednesday and T. The graphics for days 3-7 Friday through Tuesday show a frontal system well offshore through next Tuesday. So far the wildfire smoke has been staying in Eastern Lane County, but if the winds shift that might not be the case.
