NO CHANGES FROM THE PREVIOUS FORECAST AS PERSISTENCE IN THE
PATTERN ACROSS THE CENTRAL AND EASTERN PACIFIC WILL LEAD TO A
DAILY OCCURRENCE OF EASTERLY TRADES AS BROAD SURFACE RIDGING
REMAINS PARKED OVER THE NORTHERN PACIFIC. PWAT ANOMALIES WILL
REMAIN WITHIN +/- 1 STANDARD DEVIATIONS THROUGH THE NEXT 7-10 DAYS
WITH UNDULATIONS IN THE MOISTURE THROUGH THE PERIOD. WITH A
GENERALLY CONSISTENT TRADE WIND FLOW, SEASONAL TRENDS WITHIN THE
CONVECTIVE FIELD ACROSS THE ISLAND CHAIN WILL TRANSPIRE WITH THE
HEAVIEST PRECIP FOCUSED ON THE WINDWARD SIDE OF EACH ISLAND WITH
THE HIGHEST IMPACT AREA ON THE EASTERN SLOPES OF MAUNA KEA.
CONSIDERING THE PRESENCE OF BROAD RIDGING AND A STABLE UPPER
PATTERN OVER THE PACIFIC, LOOK FOR THIS TREND TO CONTINUE EVEN
BEYOND THE NEXT 7 DAYS AS INDICATED WITHIN ALL 00Z GLOBAL ENSEMBLE
SUITES.
