HAWAII EXTENDED FORECAST DISCUSSION  
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD  
343 AM EDT WED MAR 27 2024  
 
VALID 00Z THU MAR 28 2024 - 00Z THU APR 04 2024  
 
BREEZY TRADE WINDS ARE FORECAST FOR THE NEXT COUPLE OF DAYS AS A  
STRONG SURFACE HIGH SETS UP WELL NORTH OF HAWAII. MEANWHILE SOME  
WEAK TROUGHING ALOFT MAY DECREASE STABILITY A BIT AND ALLOW FOR  
SOME SHOWERS. THESE WOULD GENERALLY FAVOR WINDWARD/MAUKA AREAS  
WITH SOME POTENTIALLY SPILLING LEEWARD. BY THE WEEKEND, THE  
PRESSURE GRADIENT LOOKS TO RELAX SOMEWHAT AS THE SURFACE HIGH  
PULLS NORTHEAST, LEADING TO MODERATE TRADES WHILE MOISTURE LEVELS  
DRY OUT A BIT AND SIT AROUND AVERAGE.  
 
THEN INTO NEXT WEEK, MID-UPPER TROUGHING IS LIKELY TO STRETCH  
SOUTHWARD THROUGH MUCH OF THE PACIFIC OVER HAWAII. THIS WILL PUSH  
A SURFACE COLD FRONT AHEAD OF IT, BUT MODELS VARY REGARDING IF AND  
WHEN THIS FRONT WOULD PUSH THROUGH THE STATE. THE 00Z GFS HAS THE  
FRONT PASSING THROUGH TUESDAY-WEDNESDAY WHILE THE ECMWF HAS THE  
FRONT STALLING NORTH BUT COMING THROUGH PERHAPS MIDWEEK. IN ANY  
CASE, MOISTURE IS LIKELY TO POOL NEAR AND SOUTH OF THE FRONT,  
LEADING TO INCREASING RAIN POTENTIAL EARLY NEXT WEEK.
