HAWAII EXTENDED FORECAST DISCUSSION  
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD  
342 AM EDT SUN AUG 11 2024  
 
VALID 00Z MON AUG 12 2024 - 00Z MON AUG 19 2024  
 
TRADE WINDS SHOULD BE STRENGTHENING BACK TO BREEZY LEVELS ON  
SUNDAY AS A SURFACE HIGH DRIFTS TOWARD HAWAII (THOUGH STAYING WELL  
NORTH). THE HIGH IS FORECAST TO MEANDER AROUND 40N AND MAINTAIN  
THE TYPICAL PRESSURE GRADIENT FOR BREEZY EASTERLY TRADES THROUGH  
MUCH OF THIS WEEK, WITH SOME MODEL SIGNAL TO STRENGTHEN EVEN  
FURTHER BY LATE WEEK. THROUGH THE PERIOD, SOME SHOWERS ARE  
POSSIBLE FAVORING TYPICAL WINDWARD/MAUKA AREAS BUT OCCASIONALLY  
SPILLING INTO LEEWARD AREAS. COVERAGE AND AMOUNTS OF RAIN MAY VARY  
FROM DAY TO DAY. BY AROUND WEDNESDAY-FRIDAY, TROUGHING IN THE  
MID-UPPER LEVELS COULD SUPPORT MORE SURGES OF MOISTURE, BUT MODELS  
DO NOT NECESSARILY SHOW HIGHER RAIN AMOUNTS FOR THOSE DAYS, SO  
WILL CONTINUE TO MONITOR. WIDESPREAD HEAVY RAIN IS NOT EXPECTED,  
JUST A RELATIVELY WET TRADE WIND PATTERN.
