THE LATEST MODELS AND ENSEMBLES SHOW GOOD AGREEMENT ON AN UPPER

TO THE NORTH/WEST OF KAUAI. ENHANCED SHOWERY ACTIVITY IS ALSO
POSSIBLE ACROSS PARTS OF THE BIG ISLAND/MAUI ASSOCIATED WITH WEAK
ENERGY AND A POCKET OF HIGHER MOISTURE. AROUND WEDNESDAY OF NEXT
WEEK, GUIDANCE SHOWS THE UPPER LOW LIFTING NORTH AND EASTWARD AND
HEIGHTS RISING AGAIN OVER HAWAII, WITH LIGHTER TRADES AND SOME
