SCATTERED THUNDERSTORMS DEVELOPED WITHIN 125 MILES OF THE LINE FROM 27N 172W TO 21N 165W TO 30N 154W AND FURTHER NORTHEAST...AND WITHIN 125 MILES OF THE LINE FROM 14N 178W TO 16N 171W. ASSOCIATED DEEP CLOUD LAYERS OBSCURED LOWER FEATURES NORTH OF THE CURVE FROM 30N 169W TO 26N 177W TO 14N 173W TO 30N 150W. THIN HIGH CLOUD LAYERS ALSO WERE PRESENT UP TO ABOUT 400 MILES FURTHER SOUTHEAST. ALTHOUGH THE CLOUDS MAKING UP THIS FEATURE MOVED DIFFERENTLY DEPENDING ON HEIGHT AND LOCATION... THE FEATURE AS A WHOLE MOVED SOUTHEAST AT 5 TO 10 MILES AN HOUR. MARINE STRATOCUMULI AND LOW TO MIDDLE STRATUS LAYERS ORGANIZED INTO NOTICEABLE CLUMPS AS WIND CONVERGED ALONG AN AXIS SOUTHEAST OF THE FRONTS. THIS AREA OF CONVERGENCE WAS LOCATED WITHIN 180 MILES OF THE LINE FROM 18N 162W TO 27N 140W AND FURTHER NORTHEAST. CLOUDS NEAR THE SOUTHWEST END OF THIS FEATURE WERE ESPECIALLY WELL DEVELOPED... EVEN INCLUDING A FEW TOWERING CUMULI. TO THE SOUTH...LIGHT THUNDERSTORM ACTIVITY CONTINUED IN THE ITCZ BETWEEN 13N AND 07N. LAYERED MIDDLE TO HIGH DEBRIS CLOUDS FROM THIS AND EARLIER CONVECTION MOSTLY TO PARTLY OBSCURED LOWER FEATURES FROM 15N TO 05N. OTHERWISE...CLOUD COVER ACROSS HAWAIIAN WATERS CONSISTED MAINLY OF FRAGMENTED MARINE STRATOCUMULI AND CUMULI...THOUGH A FEW CLUMPS UP TO 150 MILES ACROSS DID OCCUR. THESE CLOUDS GENERALLY MOVED TOWARD THE WEST AT AROUND 15 MILES AN HOUR...THOUGH AS THEY APPROACHED THE FRONTS THEY TURNED TOWARD THE NORTHWEST AND THEN THE NORTH. THESE CLOUDS ROSE TYPICALLY TO HEIGHTS OF 6000 TO 9000 FEET...THOUGH TALLER CUMULI AND HIGHER CLOUD LAYERS APPROACHED 21000 FEET. ACROSS THE MAIN HAWAIIAN ISLANDS...THIN HIGH CLOUD LAYERS PARTLY OBSCURED LOWER FEATURES. WHERE THEY WERE VISIBLE...LOWER CLOUDS CONSISTED ABOUT EQUALLY OF STRATUS LAYERS EXTENDING FROM THE KAUAI CHANNEL TO MOLOKAI...AND OF LAYERED DEBRIS CLOUDS FROM TOWERING CUMULI DEVELOPING TO THE NORTHEAST CLOCKWISE THROUGH SOUTHWEST OF KAUAI. LAYERED DEBRIS CLOUDS FROM AFTERNOON CUMULUS BUILDUPS ON WEDNESDAY NO LONGER COULD BE IDENTIFIED. THESE LOWER CLOUDS VARIED CONSIDERABLY IN HEIGHT FROM 5000 TO 12000 FEET...WITH A FEW TOWERING CUMULI APPROACHING 21000 FEET. RADAR DATA FROM NEAR THE ISLANDS SHOWED AREAS OF RAIN OFFSHORE TO THE NORTHEAST CLOCKWISE THROUGH SOUTHWEST OF KAUAI...AND SCATTERED SHOWERS OVER PUNA DISTRICT ON THE BIG ISLAND...BUT ISOLATED SHOWERS AT MOST ELSEWHERE. $$ RYSHKO +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
