A SHORTWAVE TROUGH IS LOCATED ON THE EASTERN SIDE OF THE RIDGE...EXTENDING FROM 25N150W TO 21N163W...OR PASSING NEAR KAUAI. THIS TROUGH IS MOVING TO THE SOUTHEAST AT 30 MPH. AN AREA OF BROKEN TO OVERCAST LAYERED CLOUDS IS LOCATED TO THE SOUTHEAST OF THE TROUGH...COVERING A PORTION OF THE MAIN HAWAIIAN ISLANDS. THESE CLOUDS ARE LOCATED GENERALLY FROM 15N TO 23N BETWEEN 148W AND 158W. ISOLATED CUMULONIMBUS CLOUDS ARE EMBEDDED WITHIN THE LAYERED CLOUDS...WITH CLOUD TOPS EXTENDING UP TO 42000 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 30N159W. THIS TROUGH IS MOVING TO THE SOUTHEAST AT 20 MPH. ISOLATED CUMULONIMBUS CLOUDS ARE LOCATED AHEAD OF THE TROUGH...GENERALLY BETWEEN 156W AND 159W NORTH OF 28N. CLOUD TOPS EXTEND UP TO 45000 FT. BROKEN MIDDLE AND HIGH LEVEL CLOUDS ARE LOCATED THROUGH THE SAME AREA...GENERALLY BETWEEN 154W AND 160W NORTH OF 27N. THESE LAYERED CLOUDS ARE MOVING TO THE SOUTHEAST AT 40 TO 50 MPH. ACROSS THE MAIN HAWAIIAN ISLANDS...NIIHAU...KAUAI...AND OAHU ARE MOSTLY CLEAR. BROKEN LOW CLOUDS COVER THE WESTERN COAST OF MOLOKAI...WITH JUST SCATTERED CLOUDS ACROSS THE INTERIOR. BROKEN LOW CLOUDS COVER SOUTHERN SECTIONS OF LANAI...AND THE SOUTH COAST OF WEST MAUI SOUTHEAST FROM LAHAINA. BROKEN LOW CLOUDS ALSO COVER A PORTION OF THE CENTRAL VALLEY AND THE LEEWARD SLOPES OF HALEAKALA FROM PAIA TO ULUPALAKUA TO KIPAHULU. THESE LOW CLOUDS ALSO EXTEND OFFSHORE ACROSS THE LEEWARD COASTAL WATERS OF MAUI COUNTY AND ACROSS THE ALENUIHAHA CHANNEL. BROKEN LOW AND MIDDLE LEVEL CLOUDS COVER MUCH OF THE BIG ISLAND. THE CLOUDS ARE THICKEST FROM NORTH KOHALA TO NORTHERN SECTIONS OF SOUTH KONA DISTRICT...AND ACROSS PUNA AND KAU DISTRICTS. THESE CLOUDS EXTEND WELL OFFSHORE TO THE SOUTH AND EAST OF THE BIG ISLAND...AS DESCRIBED ABOVE. FARTHER WEST OF THE AREA...WATER VAPOR IMAGERY SHOWS A DEEP UPPER LEVEL LONGWAVE TROUGH LOCATED NEAR 30N175E. 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 30N170W TO 20N175W TO 16N180...OR FROM 450 MILES NORTHEAST OF MIDWAY ATOLL TO 600 MILES SOUTH SOUTHEAST OF MIDWAY TO 900 MILES SOUTH SOUTHWEST OF MIDWAY. THE BAND IS OVER 500 MILES WIDE NEAR 30N...TAPERING 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 ORGANIZED INTO TWO DISTINCT BANDS. THE LEADING BAND EXTENDS FROM 30N171W TO 20N176W...AND A SECOND BAND EXTENDS FROM 30N175W TO 19N180. AN ADDITIONAL AREA OF CIRRUS AND CIRROCUMULUS CLOUDS EXTENDS EAST FROM THE MAIN FRONTAL BAND...AND IS LOCATED GENERALLY NORTH OF 20N WEST OF 166W. THESE HIGH CLOUDS ARE MOVING TO THE SOUTH SOUTHEAST AT 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.
