HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
322 AM EDT SAT AUG 9 2025
VALID 00Z SUN 10 AUG 2025 - 00Z SUN 17 AUG 2025
POST-TROPICAL STORM HENRIETTE IS FORECAST TO TRACK WELL TO THE
NORTHEAST OF THE STATE OVER THE NEXT COUPLE OF DAYS AND TURN
NORTHWESTWARD INTO THE MID-LATITUDES MONDAY. MODELS GENERALLY
AGREE ON LOWER THAN NORMAL RAINFALL THROUGH THE NEXT WEEK THANKS
TO DRYNESS IN THE MID- LEVELS (300-700 RH < 50%). AN UPPER LOW
WILL LIKELY RETROGRADE ALONG 30N BEHIND HENRIETTE, ALLOWING TRADES
TO WEAKEN A BIT. TRADES WILL THEN GRADUALLY INCREASE INTO NEXT
WEEKEND AS HEIGHTS RISE AND THE SURFACE PRESSURE GRADIENT
STRENGTHENS.
