Marine Layer Produces Some Drizzle.
Weathernotes for Friday, June 9, 2006.
(Any updates will be found at the end of this discussion.)

Passage of a weak upper trough has deepened the marine layer and produced some drizzle overnight, and this morning, in the Los Angeles basin and valleys. As of 8:00 this morning, LAX has recorded 0.01 inch of precipitation, and several other stations have recorded amounts ranging from a trace to 0.01 inches.

This Towercam image from the UCLA Department of Physics and Astronomy Mt. Wilson 150-Foot Solar Tower Towercam shows the marine layer wasn't very thick along the San Gabriel Mountains this morning. This suggests the valleys could see at least partial clearing by mid-day, with mostly clear skies by the afternoon.

As of June 8, Downtown Los Angeles (USC) has recorded 13.19 inches this water year. This is 1.95 inches below normal, and far less than the 37.25 inches recorded last year. For Los Angeles precipitation data, the water year extends from July 1 to June 30.

The equatorial Pacific has continued to warm since this Winter's weak, and brief, La Niña. Most forecasts project that ENSO neutral conditions should persist through the end of 2006. We'll see!
