CLOUD COVER NORTHWEST OF THE BAND CONSISTED MAINLY OF COLD-AIR CUMULI...THOUGH A SECONDARY CLOUD BAND FRAGMENTING INTO COLD-AIR CUMULI WAS PRESENT WITHIN 90 MILES OF THE CURVE FROM 28N 180 TO 28N 175W TO 30N 169W. WATER VAPOR IMAGES SHOWED AN AREA OF LOW PRESSURE IN THE UPPER ATMOSPHERE TO THE EAST NORTHEAST OF THE MAIN HAWAIIAN ISLANDS.

THE NEARLY SOLID OVERCAST WAS LIMITED TO NORTHEAST OF THE CURVE FROM 30N 150W TO 26N 147W TO 25N 140W... BUT ARCS OF STRATOCUMULI REACHED AS FAR SOUTHWEST AS THE CURVE FROM 30N 154W TO 24N 150W TO 23N 140W. INDIVIDUAL STRATOCUMULUS AND CUMULUS FRAGMENTS OCCURRED FURTHER SOUTHWEST AS WELL. THESE CLOUDS GENERALLY ROSE TO HEIGHTS OF 6000 TO 9000 FEET...AND MOVED TOWARD THE SOUTHWEST AT AROUND 15 MILES AN HOUR.
