SCATTERED THUNDERSTORMS DEVELOPED UNDER THIS FEATURE WEST OF THE CURVE FROM 30N 176W TO 18N 168W TO 14N 172W TO 18N 180. ISOLATED THUNDERSTORMS ALSO DEVELOPED WITHIN 60 MILES OF THE POINT 29N 170W AND WITHIN 120 MILES OF THE POINT 26N 165W. DEEP LAYERED MIDDLE TO HIGH CLOUDS ASSOCIATED WITH THIS LOW OBSCURED LOWER FEATURES MOSTLY TO COMPLETELY NORTH OF THE CURVE FROM 20N 180 TO 22N 173W TO 15N 173W TO 15N 169W TO 19N 166W TO 14N 164W TO 17N 160W TO 20N 161W TO 21N 151W TO 30N 148W. THIS FEATURE AS A WHOLE MOVED EAST SLOWLY...WHILE THE CLOUD LAYERS MOVED SOUTHEAST AT VARIOUS SPEEDS DEPENDING ON ALTITUDE. A FRAYING BAND OF LOW TO MIDDLE CLOUD LAYERS ASSOCIATED WITH A WEAKENING FRONT EXTENDED ACROSS HAWAIIAN WATERS WITHIN 75 MILES OF THE CURVE FROM 24N 161W TO 20N 154W TO 19N 144W TO 21N 140W AND FURTHER NORTHEAST. THIS FEATURE MOVED SOUTH AT 10 TO 15 MILES AN HOUR. DENSELY PACKED COLD-AIR CUMULI PREVAILED BETWEEN THIS BAND AND 30N...LOCALLY MERGING INTO AREAS OF OVERCAST NORTH OF 22N. TO THE SOUTH...LIGHT THUNDERSTORM ACTIVITY CONTINUED IN THE ITCZ BETWEEN 11N AND 07N. 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 17N 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 NORTHWEST PARTLY TO MOSTLY OBSCURED LOWER FEATURES FROM KAUAI COUNTY TO MAUI COUNTY. WHERE THEY WERE VISIBLE...LOWER CLOUDS CONSISTED MAINLY OF LOW TO MIDDLE CLOUD LAYERS FROM THE FRONTAL CLOUD BAND MOVING ASHORE ALONG SLOPES FACING NORTHEAST TO EAST. HOWEVER... LAYERED DEBRIS CLOUDS FROM AFTERNOON CUMULUS BUILDUPS ON THURSDAY STILL LANGUISHED IN PLACES...ESPECIALLY ALONG LOWER SOUTHWEST SLOPES OF THE BIG ISLAND. THESE LOWER CLOUDS GENERALLY ROSE TO HEIGHTS OF 12000 TO 15000 FEET...IN PLACES BLENDING INTO THE HIGHER CLOUD LAYERS. RADAR DATA FROM NEAR THE ISLANDS SHOWED AREAS OF RAIN ALONG THE NORTHEAST SLOPES OF MOST ISLANDS FROM KAUAI TO THE BIG ISLAND. THESE RADAR RETURNS CORRELATED WELL WITH THE POSITION OF THE FRONTAL CLOUD BAND. OTHERWISE...RADAR DATA SHOWED ISOLATED SHOWERS AT MOST. $$ RYSHKO +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
