HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
356 AM EDT FRI APR 07 2023
VALID 00Z SAT APR 08 2023 - 00Z SAT APR 15 2023
THE PATTERN ALOFT IS FORECAST TO TRANSITION FROM AN UPPER RIDGE
FRIDAY TO MORE OF A TROUGHY PATTERN OVER THE WEEKEND. MEANWHILE AT
THE SURFACE, HIGH PRESSURE TO THE NORTH CAUSING BREEZY TRADE WINDS
MAY BE DISRUPTED A BIT THIS WEEKEND AS A FRONT APPROACHES BUT
LIKELY REMAINS NORTH OF HAWAII. THUS WINDS MAY DECREASE SLIGHTLY
INTO THE WEEKEND, BUT STILL SERVE TO FOCUS SHOWERS OVER FAVORED
WINDWARD AREAS, WITH A SLIGHT INCREASE IN INSTABILITY POSSIBLE
GIVEN THE TROUGHING ALOFT. INCREASED CLOUDS AND A FEW DOWNPOURS
ARE POSSIBLE, BUT THE CORE OF HEAVIEST RAINFALL STILL LOOKS TO
REMAIN SOUTHWEST OF THE STATE WHERE THE HIGHEST MOISTURE ANOMALIES
ARE EXPECTED. THEN THROUGH NEXT WEEK, ANOTHER REASONABLY STRONG
SURFACE HIGH LOOKS TO SHIFT EASTWARD WELL NORTH OF HAWAII (NEAR
40N), PROVIDING FOR AN INCREASE IN EASTERLY TRADES TO AT LEAST
BREEZY LEVELS LIKELY AROUND MONDAY AND LASTING THROUGH AROUND
THURSDAY. SHOWERS MAINLY IN WINDWARD AREAS CAN BE EXPECTED, WITH A
POSSIBLE INCREASE IN COVERAGE AROUND WEDNESDAY AS THERE IS
POTENTIAL FOR THE MOISTURE REMNANTS OF THE FORMER FRONT TO STRETCH
ACROSS THE STATE.
