LATEST GUIDANCE CONTINUES TO SHOW A TYPICAL TRADE PATTERN THROUGH  
THE NEXT SEVEN DAYS, SUPPORTED BY HIGH PRESSURE MEANDERING TO THE  
NORTH OF THE STATE. EXPECT BRISK TO STRONG WINDS LATE THIS WEEK  
THROUGH THE WEEKEND, FOLLOWED BY SOMEWHAT LOWER WIND SPEEDS NEXT  
TUESDAY-THURSDAY. ASIDE FROM AN AREA OF MOISTURE BRUSHING THE  
NORTHWESTERN ISLANDS ON FRIDAY, PRECIPITABLE WATER VALUES SHOULD  
REMAIN BELOW CLIMATOLOGY--HELPING TO KEEP PRIMARILY  
WINDWARD/MOUNTAIN FOCUSED SHOWERS ON THE LIGHTER SIDE MOST OF THE  
TIME. SOME DEGREE OF UPPER RIDGING WILL PASS THROUGH THE REGION  
DURING THE WEEKEND, FOLLOWED BY AN UPPER LOW THAT MAY APPROACH  
FROM THE EAST BY NEXT WEDNESDAY-THURSDAY. CLUSTERING IS STILL  
BETTER THAN AVERAGE FOR THIS LATTER FEATURE BUT WITH A SLOWER  
TREND VERSUS YESTERDAY'S GUIDANCE.
