An Upper Level Low  is moving eastward and will weaken the moisture flow to the Pacific Northwest. A surface low with it associated cold front are shown approaching the California coast keeping the weaker flow of coastal moisture still aimed our way. The graphics for days 1-3  show the frontal system, as described above, sliding southward away from us.. The graphics for days 3-7  Friday through next Tuesday show a quiet weather pattern with a frontal system lingering offshore.

Here is my weekly weather quiz question for the last time. What is the “Lifted Index? Here is the correct answer.  Lifted Index(abbrev. LI)- A common measure of atmospheric instability. Its value is obtained by computing the temperature that air near the ground would have if it were lifted to some higher level (around 18,000 feet, usually) and comparing that temperature to the actual temperature at that level. Negative values indicate instability – the more negative, the more unstable the air is, and the stronger the updrafts are likely to be with any developing thunderstorms. However there are no “magic numbers” or threshold LI values below which severe weather becomes imminent.
