HAWAII EXTENDED FORECAST DISCUSSION

346 AM EDT WED JUL 26 2023
VALID 00Z THU JUL 27 2023 - 00Z THU AUG 03 2023
A REASONABLY STRONG SURFACE HIGH WILL MEANDER WELL NORTH OF HAWAII
AROUND 40N LATITUDE THROUGH THE REST OF THE WEEK INTO NEXT WEEK.
THE INFLUENCE OF THIS HIGH WILL LEAD TO PERSISTENT GENERALLY
MODERATE TO BREEZY EASTERLY TRADES, WITH LIKELY JUST MINOR
VARIATIONS IN SPEED FROM DAY TO DAY. THUS CLOUDS AND SHOWERS THAT
MAY FORM SHOULD FAVOR WINDWARD AND MAUKA AREAS. BUT WITH RIDGING
ALOFT OVER THE NEXT SEVERAL DAYS, AN INVERSION WILL KEEP ANY
SHOWERS SHALLOW, AND THE LATTER PART OF THIS WEEK INTO EARLY NEXT
WEEK LOOKS TO HAVE LOWER THAN NORMAL MOISTURE IN PLACE AS WELL,
LIMITING SHOWER ACTIVITY FURTHER. MODEL GUIDANCE OVERALL MAINTAINS
THAT AN UPPER TROUGH ORIENTED NORTHEAST TO SOUTHWEST IS LIKELY TO
SET UP WEST OF HAWAII BY LATE WEEK INTO THE WEEKEND, MOST LIKELY
FAR ENOUGH WEST THAT ANY ENHANCED MOISTURE BEING DRAWN NORTHWARD
SHOULD STAY WEST OF THE STATE. THUS A DRIER TRADE WIND PATTERN IS
LIKELY TO LAST THROUGH THE WEEKEND AND INTO NEXT WEEK.
