AN EMBEDDED SHORTWAVE TROUGH IS LOCATED NEAR 26N166W...OR ABOUT 600 MILES NORTHWEST OF KAUAI. THIS TROUGH IS MOVING TO THE NORTHEAST AT 30 MPH. A SECOND TROUGH IS LOCATED FROM 21N152W TO 14N160W...LOCATED JUST EAST OF THE BIG ISLAND. THIS TROUGH IS MOVING TO THE EAST AT 15 MPH. THE NORTHERN EDGE OF A 200 MILE WIDE BAND OF CLOUDS ASSOCIATED WITH A DISSIPATING FRONT EXTENDS FROM 30N162W TO 25N154W TO 22N140W. THE BAND IS COMPOSED MAINLY OF OVERCAST CUMULUS AND STRATOCUMULUS ELEMENTS...BUT WITH AREAS OF BROKEN MIDDLE AND HIGH LEVEL CLOUDS AS WELL. ISOLATED TOWERING CUMULUS AND CUMULONIMBUS CLOUDS ARE ALSO LOCATED ALONG THE WESTERN EDGE OF THIS FRONTAL BAND NORTH OF 27N. CLOUD TOPS EXTEND UP TO 34000 FT. THE OVERALL BAND IS NEARLY STATIONARY. HOWEVER INDIVIDUAL CLOUD ELEMENTS ARE MOVING TO THE NORTHWEST AT 20 MPH WEST OF 150W...AND TO THE WEST SOUTHWEST AT 15 MPH EAST OF 150W. ADDITIONAL AREAS OF BROKEN LAYERED CLOUDS ARE LOCATED SOUTH OF THE FRONTAL BAND...GENERALLY NORTH OF 15N BETWEEN 150W AND 157W. ISOLATED CUMULONIMBUS CLOUDS ARE EMBEDDED WITHIN THESE LAYERED CLOUDS. CLOUD TOPS EXTEND UP TO 46000 FT. THE CUMULONIMBUS CLOUDS THEMSELVES ARE NEARLY STATIONARY...ALTHOUGH DEBRIS CLOUDS FROM THE CONVECTION AND NEARBY CIRRUS CLOUDS ARE MOVING TO THE EAST AT 30 MPH.

INDIVIDUAL CONVECTIVE UPDRAFTS ARE SHORT LIVED...BUT ADDITIONAL CONVECTIVE CLOUDS CONTINUE TO DEVELOP THROUGH THE SAME AREA. THESE CUMULONIMBUS CLOUDS ARE EMBEDDED WITHIN A LARGER AREA OF LAYERED MIDDLE AND HIGH LEVEL CLOUDS ASSOCIATED WITH THE TWO UPPER TROUGHS. ACROSS THE MAIN HAWAIIAN ISLANDS...OVERCAST LOW CLOUDS COVER THE INTERIOR AND COASTAL SECTIONS OF KAUAI. BROKEN TO OVERCAST LOW CLOUDS COVER THE SLOPES OF THE KOOLAU AND WAIANAE RANGES ON OAHU.
