HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
341 AM EDT SAT JUN 17 2023
VALID 00Z SUN JUN 18 2023 - 00Z SUN JUN 25 2023
A PACIFIC SURFACE HIGH WELL TO THE NORTHEAST OF HAWAII WILL
MEANDER SOMEWHAT THROUGH THE WEEKEND, WITH ITS INFLUENCE EXTENDING
INTO HAWAII AND MAINTAINING MODERATE TO BREEZY EASTERLY TRADES.
MEANWHILE, A SMALL UPPER LOW IS EXPECTED TO DRIFT NEAR/ATOP THE
STATE THIS WEEKEND INTO EARLY NEXT WEEK THAT COULD ALLOW FOR A
LESSENING INVERSION ALOFT FOR SOME ENHANCED SHOWERS. GIVEN THE
TRADES, SHOWERS SHOULD FAVOR WINDWARD AND MAUKA AREAS. SLIGHTLY
ABOVE AVERAGE MOISTURE LEVELS MAY BE SEEN BUT NO MAJOR SURGES OF
TROPICAL MOISTURE ARE EXPECTED OVER THE NEXT WEEK WITH THE DEEPEST
MOISTURE CONFINED TO THE ITCZ. SHOWER COVERAGE MAY LESSEN BY
TUESDAY AND BEYOND AS THE UPPER LOW WEAKENS AND MOVES AWAY. THE
SURFACE HIGH IS FORECAST TO PRESS SOUTH AND WEST CLOSER TO THE
STATE BY MIDWEEK AND BEYOND, WHICH COULD FURTHER STRENGTHEN TRADES
TO WIDESPREAD BREEZY TO WINDY LEVELS.
