LATEST MODEL GUIDANCE IS VERY AGREEABLE THAT AN UPPER LEVEL RIDGE  
AND MEAN SURFACE HIGH PRESSURE SHOULD PREVAIL FOR MUCH OF THE NEXT  
WEEK OVER/NORTH OF HAWAII. THIS WILL MAINTAIN BRISK TO STRONG  
EASTERLY TRADE WINDS, WITH GRADUALLY INCREASING SPEEDS THROUGH THE  
WEEK AND LASTING INTO NEXT WEEKEND AS STRONG HIGH PRESSURE SETTLES  
NORTHEAST OF THE STATE. SHOWERS SHOULD FOCUS PRIMARILY OVER  
WINDWARD/MOUNTAIN LOCATIONS, WITH INCREASING MOISTURE LEADING TO  
SOME HEAVIER SHOWERS ALONG EASTERN SLOPES OF THE SOUTHERNMOST  
ISLANDS LATER IN THE WEEK/NEXT WEEKEND. AN UPPER LOW WELL NORTH OF  
HAWAII LOOKS TO PUSH UPPER RIDING EASTWARD IN ABOUT A WEEKS TIME,  
ALLOWING FOR WEAKER TRADES BY EARLY NEXT WEEK.
