Here is my new weekly weather quiz question. What is the “Lithosphere? ”
_________________
A weak Upper Level High Pressure Ridge (“Arch” shape) offshore keeps the onshore airflow going bringing cooler air to Oregon. The graphics for days 1-3 show no fronts moving over the Pacific Northwest. The graphics for days 3-7 Thursday through next Monday show a frontal system hanging offshore then moving in Saturday and Sunday.
