Here is my weekly weather quiz question. What is a “Low Pressure System? ”
________________
An Upper Level High Pressure Ridge (“Arch” shape) will keep temperatures at or a bit above normal. The graphics for days 1-3 show a dry cold front pushing through the Pacific Northwest today. The graphics for days 3-7 Friday through Tuesday show a frontal system moving through the Pacific Northwest Saturday into Sunday.
