.FROM PREVIOUS DISCUSSION...
.SHORT TERM...FOR THE CENTRAL CALIFORNIA INTERIOR...UPPER LOW OFF
THE CENTRAL CA COAST WILL CONT TO SPIN CONSIDERABLE MOISTURE INLAND
TODAY. MAIN AREA OF ENHANCED CLOUDS AND HIGHEST RAIN RATES SHOULD BE
E OF CENTRAL CA INTERIOR NEAR SUNRISE...HOWEVER VORT LOBES SPINNING

WEST COAST AT THE END OF THE WEEK WITH AN INCREASING POTENTIAL FOR
EARLY MORNING VALLEY FOG. TOWARD THE END OF THE LONG TERM...MODELS
ARE STILL ATTEMPTING TO RESOLVE A SPLIT FLOW PATTERN APPROACHES THE
WEST COAST. WILL EXPECT THE BULK OF THE ENERGY TO MOVE INTO THE
PACIFIC NORTHWEST WITH ONLY SOME MID AND HIGH LEVEL MOISTURE FROM
