HEIGHTS WILL LOWER A BIT INTO THE WEEKEND DUE TO TROUGHING TO THE
NORTHEAST OF THE REGION WITH MAINLY SCATTERED WINDWARD SHOWERS
AMID LIGHT TRADES. A LEFTOVER MOISTURE AXIS FROM AN OLD FRONT WILL
LINGER FOR A COUPLE MORE DAYS OVER KAUAI AND OAHU WITH LOWER PW
VALUES TO THE SOUTHEAST. SHOWERS WILL BE MORE WIDESPREAD OVER
THESE NORTHERN ISLANDS.NEXT WEEK, ENSEMBLES AGREE ON RISING
HEIGHTS TO THE NW AND SE OF THE 50TH STATE THAT EVENTUALLY
CONVERGE OVER HAWAI`I DURING THE MIDDLE OF THE WEEK, PROMOTING A
RATHER QUIET AND DRIER PATTERN WITH SLOWLY INCREASING TRADES DUE
TO STRENGTHENING SFC HIGH PRESSURE TO THE NORTHEAST. BY LATER NEXT
WEEK, THE UPPER HIGH MAY SPLIT TO THE NORTHEAST AND SOUTHWEST OF
THE AREA, LEAVING A RELATIVE WEAKNESS OVER HAWAI`I ITSELF.
