Here is my new weekly weather quiz question. “What is a “Sling Psychometer?”
____________
Upper Level High Pressure will very slowly start to increase our temperatures. 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 Sunday through Thursday show a cold frontal system sliding through the Pacific Northwest next Wednesday.
