THIN LAYERED HIGH CLOUDS ALSO PARTLY OBSCURED LOWER FEATURES UP TO ABOUT 320 MILES SOUTHEAST FROM THE LEADING EDGE OF THE MAIN CLOUD BAND. THIS FEATURE AS A WHOLE MOVED EAST SLOWLY. A STATIONARY AREA OF DENSE LAYERED CLOUDS POSSIBLY ASSOCIATED WITH THIS FRONT OBSCURED LOWER FEATURES WITHIN 180 MILES OF THE POINT 13N 180. ANOTHER BAND OF LOW TO MIDDLE CLOUD LAYERS ASSOCIATED WITH A SECOND FRONT EXTENDED ACROSS HAWAIIAN WATERS WITHIN 120 MILES OF THE CURVE FROM 30N 163W TO 25N 153W TO 25N 144W TO 26N 140W AND FURTHER NORTHEAST. DENSELY PACKED COLD-AIR CUMULI PREVAILED BETWEEN THIS BAND AND 30N. THIS FEATURE MOVED SOUTHEAST AT 5 TO 10 MILES AN HOUR. TO THE SOUTH...VERY LIGHT THUNDERSTORM ACTIVITY CONTINUED IN THE ITCZ BETWEEN 12N AND 05N. LAYERED MIDDLE TO HIGH DEBRIS CLOUDS FROM THIS AND EARLIER CONVECTION PARTLY TO MOSTLY OBSCURED LOWER FEATURES BETWEEN 03N AND THE CURVE FROM 09N 180 TO 11N 158W TO 19N 152W TO 19N 140W. ISOLATED TOWERING CUMULI AND POSSIBLE THUNDERSTORMS DEVELOPED WITHIN 36 MILES OF THE LINE FROM 17N 157W TO 18N 155W. LAYERED MIDDLE TO HIGH DEBRIS CLOUDS FROM THIS AND EARLIER CONVECTION PARTLY OBSCURED LOWER FEATURES WITHIN ABOUT THE SAME AREA. OTHERWISE...CLOUD COVER ACROSS HAWAIIAN WATERS CONSISTED MAINLY OF SMALL UNORGANIZED CLUMPS OF MARINE CUMULUS AND STRATOCUMULUS. THESE CLOUDS GENERALLY DRIFTED WEST SLOWLY. THEY ROSE MOSTLY TO HEIGHTS OF 5000 TO 7000 FEET...THOUGH TALLER CUMULI APPROACHED 15000 FEET. ACROSS THE MAIN HAWAIIAN ISLANDS...CLOUD COVER CONSISTED MOSTLY OF AFTERNOON CUMULUS...TOWERING CUMULUS...AND THUNDERSTORM BUILDUPS WITH THEIR LAYERED DEBRIS CLOUDS OVER HIGHER TERRAIN. THE MOST ACTIVE CONVECTION OCCURRED OVER NORTH KAUAI AND NORTH CLOCKWISE THROUGH NORTHEAST OAHU. AREAS WITH THE LEAST CLOUD COVER WERE LIMITED MAINLY TO NORTHEAST NIIHAU...SOUTHWEST COASTAL KAUAI...SOUTH OAHU...EAST MOLOKAI...SOUTHEAST LANAI...THE CENTRAL ISTHMUS ON MAUI...THE WEST COAST OF NORTH AND SOUTH KOHALA DISTRICTS ON THE BIG ISLAND...THE VICINITY OF CAPE KUMUKAHI ON THE BIG ISLAND...AND THE VICINITY OF KAUNA POINT ON THE BIG ISLAND. RADAR DATA FROM NEAR THE ISLANDS SHOWED HEAVY SHOWERS ALONG THE NORTHEAST COAST OF OAHU AND OFFSHORE JUST TO THE WEST OF THE BIG ISLAND...SCATTERED SHOWERS ALONG THE NORTH COAST OF KAUAI AND ALONG THE SOUTHEAST COAST OF THE BIG ISLAND...BUT ISOLATED SHOWERS AT MOST ELSEWHERE. THE LOWER CLOUDS VARIED CONSIDERABLY IN HEIGHT FROM 5000 TO 15000 FEET...WHILE THE TOWERING CUMULI EXCEEDED 20000 FEET...AND THE THUNDERSTORMS APPROACHED 32000 FEET. $$ RYSHKO +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
