Here is my new weekly weather quiz question. What is a “Low Pressure System? ”
________________
An Upper Level High Pressure Ridge (“Arch” shape) will keep temperatures near or a bit above normal. The graphics for days 1-3 show a frontal system approaching the Pacific Northwest Tuesday morning. The graphics for days 3-7 Thursday through Monday show a frontal system moving through the Pacific Northwest Saturday into next Sunday.
