ANOTHER SURFACE TROUGH LIES WEST OF THE ISLANDS ALONG AN AXIS FROM 23N172W TO 16N168W. THESE FEATURES ARE EASILY SEEN GIVEN THE BROKEN STABLE LOW CLOUD COVER ACROSS THE CENTRAL NORTH PACIFIC NORTH OF A LINE FROM 12N140W TO 15N150W TO 18N170W...AND SOUTH OF A LINE FROM 18N140W TO 30N161W. WATER VAPOR LOOP...SHOWING FEATURES MAINLY ABOVE ABOUT 24000 FEET...SHOWS AN UPPER LOW WEST OF THE ISLANDS NEAR 20N166W. THE UPPER LOW IS MOVING TOWARD THE WEST SLOWLY...WHILE THE SURFACE TROUGHS APPEAR TO BE MOVING TOWARD THE WEST AT 10 TO 15 MPH. CLOUD COVER ACROSS LOCAL WATERS HAS DECREASED SINCE THIS MORNING...BUT CONTINUES TO FAVOR WINDWARD AND MAUKA AREAS OF THE ISLANDS THEMSELVES. BROKEN TO OVERCAST LOW CLOUDS COVER ALMOST ALL OF KAUAI. HOWEVER...THIS IS DUE TO A PATCH OF LOW CLOUDS ABOUT THE SIZE OF THAT ISLAND MOVING ACROSS IN THE TRADES. SKIES MAY CLEAR ACROSS AT LEAST THE LEEWARD HALF OF KAUAI WITHIN THE NEXT HOUR OR SO. BROKEN LOW CLOUDS COVER THE KOOLAU SUMMITS AND WINDWARD SLOPES OF OAHU AS WELL AS THE SOUTHERN FRINGE ACROSS HONOLULU AND THE EWA PLAIN. THE EASTERN THIRD OF MOLOKAI HAS SCATTERED TO BROKEN LOW CLOUDS. BROKEN LOW CLOUDS PERSIST ACROSS MAUKA SECTIONS OF LANAI. MAUI HAS OVERCAST LOW CLOUDS ACROSS WINDWARD AND NORTHWEST-FACING HALEAKALA SLOPES AS WELL AS ACROSS WINDWARD WEST MOUNTAIN SLOPES. OVERCAST LOW CLOUDS COVER WINDWARD BIG ISLAND SLOPES SOUTH OF LAUPAHOEHOE...WRAPPING SOUTHWEST ACROSS SOUTH-FACING PUNA SLOPES. LOW CLOUD COVER HAS GREATLY INCREASED ACROSS KAU AND LEEWARD SLOPES OF THE BIG ISLAND...WITH OVERCAST LOW CLOUDS NOTED FROM KAU AROUND SOUTH POINT AND UP THE KONA SIDE THROUGH KAILUA-KONA. A SMALL PATCH OF BROKEN TO OVERCAST LOW CLOUDS IS POISED TO CROSS PUNA AND HILO DISTRICTS OF THE BIG ISLAND. OTHERWISE WINDWARD WATERS HAVE SCATTERED LOW CLOUDS. EXCEPT FOR THE BIG ISLAND PLUME EXTENDING WEST FROM THE SOUTH KONA SHORELINE...LEEWARD WATERS HAVE SCATTERED LOW CLOUDS TO CLEAR SKIES. LOW CLOUDS ARE MOVING ACROSS HAWAIIAN WATERS AT ABOUT 20 MPH...WITH SWIFTER CLOUD MOTION NOTED IN THE EASTERN CHANNELS AND SOUTH OF THE BIG ISLAND. SOUTH OF THE ISLANDS...ISOLATED CUMULONIMBUS...CB...ARE FLARING WITHIN A RAGGED 120 MILE WIDE BAND CENTERED ALONG A LINE FROM 10N148W TO 08N162W. ADDITIONAL CB ARE NEAR 12N140W. $$ POWELL +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
