VALID 00Z TUE JUN 18 2024 - 00Z TUE JUN 25 2024  
 
TODAY'S MODELS AND ENSEMBLES CONTINUE TO SHOW A PERSISTENT TRADE  
PATTERN WITH HIGH PRESSURE TO THE NORTH (DRIFTING INCREMENTALLY  
WESTWARD WITH TIME) SUPPORTING BRISK WINDS AND PRIMARILY  
WINDWARD/MOUNTAIN FOCUS FOR SHOWERS. SLOW STRENGTHENING OF THE  
SURFACE HIGH MID-LATE WEEK SHOULD YIELD RELATIVELY STRONGER WINDS  
FROM WEDNESDAY INTO THE WEEKEND. GUIDANCE IS FAIRLY CONSISTENT IN  
DEPICTING THE MOISTURE FLUCTUATIONS THAT MAY AFFECT THE GENERALLY  
LIGHT TO MODERATE RAINFALL TOTALS FORECAST DURING THE PERIOD. AN  
UPPER LOW INITIALLY TRACKING WESTWARD JUST SOUTH OF THE STATE WILL  
BRING A MODEST BAND OF MOISTURE THROUGH THE ISLANDS FROM EAST TO  
WEST DURING TUESDAY-WEDNESDAY, FOLLOWED BY A DRIER BAND ON  
THURSDAY AND A MOIST POCKET PASSING THROUGH FRIDAY-SATURDAY. WITH  
THIS LATTER MOISTURE, THE HIGHEST PRECIPITABLE WATER VALUES SHOULD  
CROSS THE NORTHWESTERN ISLANDS. THEN EXPECT MOISTURE TO DECREASE  
SUNDAY-MONDAY.
