A SHORTWAVE TROUGH IS LOCATED ON THE EASTERN SIDE OF THE RIDGE...EXTENDING FROM 25N154W TO 20N161W...OR PASSING OVER THE WESTERN HALF OF THE MAIN HAWAIIAN ISLANDS. THIS TROUGH IS MOVING TO THE SOUTHEAST AT 20 MPH. AN AREA OF BROKEN LAYERED CLOUDS IS LOCATED TO THE SOUTHEAST OF THE TROUGH...COVERING A PORTION OF THE STATE. THESE CLOUDS ARE LOCATED GENERALLY FROM 16N TO 24N BETWEEN 149W AND 157W. ISOLATED CUMULONIMBUS CLOUDS ARE EMBEDDED WITHIN THE LAYERED CLOUDS...WITH CLOUD TOPS EXTENDING UP TO 44000 FT. THE INDIVIDUAL CUMULONIMBUS CELLS ARE NEARLY STATIONARY. HOWEVER CIRRUS DEBRIS FROM THE CONVECTION IS MOVING TO THE EAST AT 30 MPH. A SECOND SHORTWAVE TROUGH IS LOCATED FARTHER NORTH NEAR 29N157W. THIS TROUGH IS MOVING TO THE SOUTHEAST AT 25 MPH. BROKEN MIDDLE AND HIGH LEVEL CLOUDS ARE LOCATED AHEAD OF THE TROUGH...GENERALLY BETWEEN 150W AND 159W NORTH OF 26N. WEAKENING CUMULONIMBUS CLOUDS ARE EMBEDDED WITHIN THE WESTERN EDGE OF THESE LAYERED CLOUDS. CLOUD TOPS EXTEND UP TO 40000 FT. DISTINCT TRANSVERSE BANDS ARE VISIBLE EXTENDING DOWNSTREAM FROM THIS CONVECTION...A SIGN OF POTENTIAL HIGH LEVEL TURBULENCE. ACROSS THE MAIN HAWAIIAN ISLANDS...BROKEN LOW CLOUDS COVER THE INTERIOR AND SOUTHERN SECTIONS OF KAUAI AND NIIHAU. BROKEN TO OVERCAST CUMULUS AND TOWERING CUMULUS CLOUDS COVER THE INTERIOR AND SOUTHEAST SECTIONS OF OAHU....AS WELL AS WESTERN SECTIONS OF MOLOKAI AND INTERIOR SECTIONS OF LANAI. THESE CLOUDS ALSO EXTEND OFFSHORE 15 MILES TO THE NORTH OF MOLOKAI AND LANAI. BROKEN TO OVERCAST CLOUDS COVER THE WEST MAUI MOUNTAINS AND SLOPES OF HALEAKALA UP TO SUMMIT LEVEL...WITH SCATTERED TO BROKEN CLOUDS ACROSS THE CENTRAL VALLEY. BROKEN TO OVERCAST CUMULUS AND TOWERING CUMULUS CLOUDS COVER THE BIG ISLAND AS WELL...EXTENDING ACROSS THE SADDLE AND TO THE SUMMITS OF MAUNA KEA AND MAUNA LOA. FARTHER WEST OF THE AREA...WATER VAPOR IMAGERY SHOWS A DEEP UPPER LEVEL LONGWAVE TROUGH LOCATED NEAR 30N177E. THIS TROUGH IS MOVING TO THE NORTHEAST AT 25 MPH. A COLD FRONT ASSOCIATED WITH THIS TROUGH IS LOCATED NEAR THE INTERNATIONAL DATELINE...AND A BROKEN TO OVERCAST AREA OF DEEP LAYERED CLOUDS IS ASSOCIATED WITH THE COLD FRONT. THE LEADING EDGE OF THIS FRONTAL BAND EXTENDS FROM 30N168W TO 21N173W TO 16N180...OR FROM 600 MILES EAST NORTHEAST OF MIDWAY ATOLL TO 500 MILES SOUTH SOUTHEAST OF MIDWAY TO 900 MILES SOUTH SOUTHWEST OF MIDWAY. THE BAND IS CLOSE TO 600 MILES WIDE NEAR 30N...AND TAPERS DOWN TO 300 MILES WIDE NEAR 16N. WHILE THE OVERALL BAND IS MOVING TO THE EAST AT 10 TO 15 MPH...INDIVIDUAL CLOUD ELEMENTS ARE MOVING TO THE NORTH NORTHEAST AT UP TO 50 MPH. SCATTERED CUMULONIMBUS CLOUDS ARE EMBEDDED WITHIN THE LAYERED CLOUDS. CONVECTIVE CLOUD TOPS EXTEND UP TO 48000 FT. THE CUMULONIMBUS CLOUDS ARE GREATEST IN COVERAGE ALONG A LINE THAT EXTENDS ROUGHLY FROM 30N174W TO 21N178W. AN ADDITIONAL AREA OF CIRRUS AND CIRROCUMULUS CLOUDS EXTENDS EAST FROM THE MAIN FRONTAL BAND...AND IS LOCATED GENERALLY NORTH OF 20N WEST OF 164W. THESE HIGH CLOUDS ARE MOVING TO THE SOUTH SOUTHEAST AT 40 TO 50 MPH. $$ BRAVENDER +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
