Here is my weekly weather quiz question. What is a “Monsoon? ”
________________
An Upper Level Low Pressure Trough (“U” shape) keeps our weather pattern stable with normal temperatures. The graphics for days 1-3 show the cold front that pushed through the Pacific Northwest. The graphics for days 3-7 Sunday through Thursday show no frontal activity pushing into or through Oregon during the period until a cold front shows up to our northwest Wednesday and next.
