THIS FEATURE DID LITTLE TO INFLUENCE THE WEATHER ACROSS THE STATE...AND CONTINUED TO MOVE FURTHER AWAY TOWARD THE EAST. WATER VAPOR IMAGES ALSO SHOWED A BROADER AND MORE ACTIVE LOW IN THE UPPER ATMOSPHERE NEAR THE DATELINE. ISOLATED THUNDERSTORMS DEVELOPED UNDER THIS FEATURE WEST OF THE CURVE FROM 27N 180 TO 16N 163W TO 17N 180. DEEP LAYERED MIDDLE TO HIGH CLOUDS ASSOCIATED WITH THIS LOW OBSCURED LOWER FEATURES MOSTLY TO COMPLETELY WITHIN 275 MILES OF THE LINE FROM 18N 167W TO 30N 164W...AND PARTLY OVER THE AREA NORTH OF 16N AND WEST OF 158W. THIS FEATURE MOVED EAST SLOWLY. A BAND OF LOW TO MIDDLE CLOUD LAYERS ASSOCIATED WITH A FRONT EXTENDED ACROSS HAWAIIAN WATERS WITHIN 75 MILES OF THE CURVE FROM 25N 162W TO 21N 148W TO 23N 141W TO 27N 135W TO 30N 133W AND FURTHER NORTH. THIS FEATURE MOVED SOUTH AT 5 TO 10 MILES AN HOUR. DENSELY PACKED COLD-AIR CUMULI PREVAILED BETWEEN THIS BAND AND 30N. TO THE SOUTH...VERY LIGHT THUNDERSTORM ACTIVITY CONTINUED IN THE ITCZ BETWEEN 10N AND 06N. LAYERED MIDDLE TO HIGH DEBRIS CLOUDS FROM THIS AND EARLIER CONVECTION PARTLY OBSCURED LOWER FEATURES WITHIN ABOUT THE SAME RANGE OF LATITUDE. OTHERWISE...CLOUD COVER ACROSS HAWAIIAN WATERS CONSISTED MOSTLY OF CUMULUS AND STRATOCUMULUS FRAGMENTS...THOUGH THESE CLOUDS DID TEND TO CLUMP TOGETHER LOOSELY BETWEEN 20N AND 14N. THEY GENERALLY ROSE TO HEIGHTS OF 6000 TO 9000 FEET...AND MOVED TOWARD THE WEST AT AROUND 20 MILES AN HOUR. ACROSS THE MAIN HAWAIIAN ISLANDS...LAYERED HIGH CLOUDS FROM THE WEST PARTLY TO MOSTLY OBSCURED LOWER FEATURES. WHERE THEY WERE VISIBLE...LOWER CLOUDS CONSISTED MAINLY OF AFTERNOON CUMULUS BUILDUPS WITH THEIR LAYERED DEBRIS CLOUDS OVER HIGHER TERRAIN INLAND. HOWEVER...A FEW MARINE CUMULI DID MOVE ASHORE ALONG SLOPES FACING NORTHEAST TO EAST...AND THE FRONTAL CLOUD BAND ALSO APPROACHED MAUI COUNTY...OAHU...AND KAUAI FROM THE NORTHEAST. THESE LOWER CLOUDS GENERALLY ROSE TO HEIGHTS OF 10000 TO 11000 FEET. RADAR DATA FROM NEAR THE ISLANDS SHOWED SCATTERED SHOWERS ALONG NORTH SLOPES OF KAUAI...OAHU...MOLOKAI...AND MAUI...AND AREAS OF RAIN OFFSHORE TO THE NORTH OF THESE ISLANDS...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.
