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 keeping temperatures at a more normal level. As it moves temperatures will slowly increase. The graphics for days 1-3 show a couple frontal systems east of moving through Oregon. The graphics for days 3-7 Thursday through Monday show a cold frontal system approaching the Pacific Northwest Monday and Tuesday.
