AN UPPER LEVEL JET IS CRISS-CROSSING THE AREA TO THE SOUTH OF THESE FEATURES RUNNING FROM 15N170W TO THE MAIN HAWAIIAN ISLANDS AND OFF TO THE EAST NORTHEAST OVER 1000 MILES. ALL OF THE UPPER LEVEL FEATURES ARE RESULTING IN SCATTERED THUNDERSTORM ACTIVITY AND PLENTY OF LAYERED CIRRUS MOVING FROM THE DEEP 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 165W AND 175W. THESE STORMS ARE NEARLY STATIONARY AND EMBEDDED IN LAYERED MID AND HIGH CLOUDS.
