Here is my new weekly weather quiz question. What is the “Lithosphere? ”
_________________
An Upper Level Low Pressure Trough (“U” shape) to our northwest keeps us in normal temperatures with onshore airflow. The graphics for days 1-3 show a cold front moving over the Pacific Northwest Friday. The graphics for days 3-7 Saturday through next Wednesday show a frontal system hanging offshore then moving in Saturday and Sunday.
