HAWAII EXTENDED FORECAST DISCUSSION  
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD  
306 AM EDT SUN JUL 28 2024  
 
VALID 00Z MON JUL 29 2024 - 00Z MON AUG 05 2024  
 
HIGH PRESSURE NORTH OF HAWAII WILL CONTINUE TO SUPPORT SOME GUSTY  
WINDS THROUGH SUNDAY, WITH SPEEDS GENERALLY DECREASING THEREAFTER  
AS THE HIGH PUSHES WESTWARD AND UPPER TROUGHING APPROACHES FROM  
THE NORTHEAST. GUIDANCE AGREES THAT MOST OF THE MAIN ISLANDS  
SHOULD REMAIN IN AN AXIS OF BELOW-CLIMATOLOGY PRECIPITABLE WATER  
VALUES FOR MUCH OF THE WEEK KEEPING RAINFALL TOTALS ON THE LIGHT  
SIDE. BY TUESDAY-THURSDAY THERE IS SOME SPREAD FOR DETAILS OF THE  
UPPER TROUGH PUSHING IN FROM THE NORTHEAST AND SLIDING NORTH OF  
HAWAII, BUT THE ENSEMBLE MEANS OFFER A REASONABLE STARTING POINT  
FOR THIS ASPECT OF THE FORECAST. TRADES MAY INCREASE AGAIN LATER  
NEXT WEEK AS AN UPPER RIDGE BUILDS EAST/OVER THE ISLANDS.
