THE SUBTROPICAL HIGH WILL REMAIN IN PLACE TO THE NORTH OF THE  
STATE THROUGH THE WEEK THEN SHIFT TO THE NORTHEAST THIS WEEKEND,  
AND NORTHEASTERLY TO EASTERLY TRADE WINDS WILL PERSIST. THIS  
PATTERN WILL FAVOR PRECIPITATION CHANCES EACH DAY FOR WINDWARD  
LOCATIONS, AND CONDITIONS WILL REMAIN MAINLY DRY FOR SOUTHWESTERN  
PORTIONS OF THE ISLANDS. A LOW PRESSURE SYSTEM IS FORECAST TO  
DEVELOP TO THE NORTHWEST OVER THE WEEKEND AND BRING A TRAILING  
FRONT TOWARDS THE NORTHERNMOST ISLANDS NEXT WEEK, BUT THE FRONT  
WILL LIKELY BE BLOCKED BY THE SUBTROPICAL RIDGE AND REMAIN  
NORTHWEST OF THE STATE.
