Here is my new weekly weather quiz question. “What is a “Sling Psychometer?”
____________
An Upper Level Low remains offshore and that means more onshore airflow. As it moves temperatures will slowly increase. The graphics for days 1-3 show a frontal system east of Oregon today. The graphics for days 3-7 Thursday through Monday show a cold frontal system approaching the Pacific Northwest Wednesday.
