Here is my 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 moving southward this afternoon and tonight. The graphics for days 3-7 Monday through next Friday show a quiet weather pattern until a frontal system slides into the Pacific Northwest next Monday then a complex frontal system will be offshore to our northwest next Thursday .
