HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
332 AM EDT THU AUG 22 2024
VALID 00Z FRI AUG 23 2024 - 00Z FRI AUG 30 2024
...MONITORING TROPICAL SYSTEM DEVELOPMENT AND POSSIBLE
ISLAND/MARITIME WEEKEND IMPACTS...
MODEL AND ENSEMBLE FORECASTS GENERALLY REMAIN REASONABLY WELL
CLUSTERED FOR THE REMAINDER OF THE WEEK. A FAVORED MODEL COMPOSITE
SUPPORTS QUITE BREEZY TRADES WITH SURFACE HIGH PRESSURE BUILDING
AND BRIDGING TO THE NORTH OF THE STATE. SHOWERS ARE LIKELY TO
FAVOR TYPICAL WINDWARD/MAUKA AREAS THIS WEEK, BUT MAY OCCASIONALLY
SPILL INTO LEEWARD AREAS.
RECENT FORECAST SIGNALS SHOW POTENTIAL TO BRING DEEP MOISTURE INTO
AT LEAST THE BIG ISLAND LATER THIS WEEKEND INTO EARLY NEXT WEEK
WITH ORIGINS FROM POSSIBLE TROPICAL LOW/CONVECTIVE DEVELOPMENTS
STILL BEING MONITORED STILL WELL TO THE SOUTHEAST OF THE ISLANDS
BY THE NATIONAL HURRICANE CENTER AND CENTRAL PACIFIC HURRICANE
CENTER. UNCERTAIN SYSTEM PROXIMITY IN THIS SCENARIO MAY OFFER
POTENTIAL TO SUPPORT A MUCH WETTER AND WINDY PERIOD ALONG WITH
SIGNIFICANT MARITIME HAZARDS.
