Here is my new weekly weather quiz question. What is the “Lifted Index?

_________________

An Upper Level Low  is sliding down the California coast keeping the flow of coastal moisture aimed our way. The graphics for days 1-3  show a frontal system just offshore Thursday. The graphics for days 3-7  Saturday through next Wednesday show a quiet weather pattern until a frontal system slides into the Pacific Northwest next Sunday. Another front will be offshore next Wednesday.
