AN UPPER LEVEL JET IS CRISS-CROSSING THE AREA TO THE SOUTH OF THESE TROUGHS...RUNNING FROM 15N170W TO THE MAIN HAWAIIAN ISLANDS AND OFF TO THE EAST NORTHEAST OVER 1000 MILES. ALL OF THESE UPPER LEVEL TROUGHS ARE HELPING TO ORGANIZE SCATTERED THUNDERSTORM ACTIVITY...AND THE UPPER JET IS SPREADING SCATTERED LAYERED CIRRUS FROM DEEP TROPICAL CONVECTION ACROSS THE MAIN HAWAIIAN ISLANDS. INFRARED IMAGERY SHOWS THE GREATEST CONCENTRATION OF SCATTERED THUNDERSTORMS...WITH TOPS TO 50000 FEET...IN THE AREA FROM 22N TO 16N BETWEEN 167W AND 177W.
