COASTAL AREAS ALONG THE EAST...SOUTH AND SOUTHWEST SHORES ARE MOSTLY SUNNY ASIDE FROM THE HIGH LEVEL CIRRUS. ALTHOUGH SKIES OVER NIIHAU CONTINUE TO BE MOSTLY SUNNY...AN AREA OF BROKEN CU EXTENDS UP TO 50 MILES TO WEST AND SOUTHWEST OF THE ISLAND. THIN CIRRUS ELEMENTS ARE ALSO IN THE VICINITY OF OAHU...WITH BROKEN CU OVER THE RIDGE OF THE KOOLAU RANGE AND THE LOWER WINDWARD SLOPES...WITH PRIMARILY SCATTERED CU OVER THE REMAINDER OF THE ISLAND. A PATCH OF BROKEN CU IS OVER THE NEAR SHORE WATERS NORTH OF MAUI...AND EAST OF MOLOKAI... AND IS CONTRIBUTING TO THE BROKEN CU THAT ALREADY EXISTS OVER EASTERN MOLOKAI...THE LOWER SLOPES OF THE WEST MAUI MOUNTAINS...AND THE LOWER WINDWARD SLOPES OF HALEAKALA.

SCATTERED THUNDERSTORMS ARE LOCATED NEAR THE CORE OF THE LOW...FROM 23N TO 28N BETWEEN 173W AND 178W...AND THE CIRRUS CLOUDS COVER THE AREA FROM 12N TO 23N BETWEEN 161W AND 174W. A TROUGH ALOFT EXTENDS SOUTHWARD FROM THE LOW...AND IS LOCATED ALONG A LINE FROM THE LOW TO 14N 175W. SCATTERED THUNDERSTORMS ARE LOCATED NEAR THE BASE OF THE TROUGH...FROM 05N TO 13N BETWEEN 170W AND 180. THE NORTHEASTERN EDGE OF THE MASS OF HIGH CLOUDS IS NEAR KAUAI AND OAHU...WITH THE CIRRUS DEVELOPING WITHIN THE SOUTHWEST FLOW ASSOCIATED WITH THE TROUGH ALOFT. A PAIR OF WEAK DISTURBANCES LOCATED ABOUT 550 TO 800 MILES SOUTH AND SOUTHEAST OF THE BIG ISLAND ARE TRIGGERING ISOLATED THUNDERSTORMS...BUT LACK SIGNIFICANT ORGANIZATION...ALTHOUGH UPPER LEVEL WINDS APPEAR TO BE MARGINALLY CONDUCIVE FOR FURTHER DEVELOPMENT. $$ BIRCHARD +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
