A MESSY FRONTAL BAND CONTINUES TO MOVE EAST NEAR 30 MPH. THE
FRONTAL BAND IS MARKED BY A WIDE AREA OF OVERCAST LAYERED CLOUDS
WITH SCATTERED THUNDERSTORMS WITHIN 150 MILES EITHER SIDE OF A
LINE FROM NORTH OF 30N 143W TO 20N 148W THEN WEAKENS AND THINS TO
A 50 MILE WIDE BAND OF CUMULUS /CU/ AND TOWERING CUMULUS /TCU/
FROM 20N 148W THROUGH 17N 154W. THE MAIN PORTION OF THE FRONT IS
BEING SUPPORTED BY AN UPPER LEVEL TROUGH...WITH ITS AXIS RUNNING
FROM NORTH OF 30N 148W TO 18N 148W...AS SEEN ON THE WATER VAPOR
IMAGERY. MOST OF THE THUNDERSTORM ACTIVITY IS BETWEEN 19N AND 22N
ALONG THE FRONT AND MAXIMUM CLOUD TOPS NORTH OF 20N ARE UPWARDS OF
43 THOUSAND FEET. SOUTH OF 20N...TCU TOPS REACH NEAR 18 THOUSAND
FEET. A JET ON THE FAR EASTERN FLANK OF THE UPPER LEVEL TROUGH IS
HELPING TO CARRY A BROAD AREA OF HIGH LEVEL CLOUDS NORTHEAST. THE
AREA OF CLOUDS IS MAINLY WITHIN 200 MILES EITHER SIDE OF A LINE
FROM 30N 134W TO 12N 139W.
A SECOND WEAKER FRONT INTERSECTS THE FAR NORTHWESTERN CORNER OF
THE AREA. THE LEADING EDGE OF THE FRONTAL BAND RUNS FROM NORTH OF
30N 169W TO WEST OF 23N 180W WITH BROKEN CU AND TCU FILLING IN 200
MILES TO THE NORTHWEST. MAXIMUM CLOUD TOPS ARE NEAR 17 THOUSAND
FEET. BROKEN TO OVERCAST HIGH CLOUDS ARE WITHIN 100 MILES EITHER
SIDE OF A LINE FROM 34N 170W TO 27N 173E. WEST OF 170W...THE HIGH
CLOUDS SPREAD TO WITHIN 200 MILES OF A LINE FROM 34N 158W TO 34N
170W.
THE INTERTROPICAL CONVERGENCE ZONE REMAINS FAIRLY QUIET THIS
AFTERNOON WITH MOST LAYERED CLOUDS REMAINING SOUTH OF 10N AND ONLY
FEW THUNDERSTORMS. A THIRD AREA OF HIGH CLOUDS BETWEEN 15N AND
10N ARE MOVING TO THE EAST FROM WEST OF 180W THROUGH 150W. THE
HIGH CLOUDS ARE MOVING ALONG AN AREA OF WESTERLY WINDS.
THE CONDITIONS OVER THE MAIN HAWAIIAN ISLANDS REMAIN QUIET THIS
AFTERNOON. SCATTERED CU AND STRATOCUMULUS /SC/ ARE PASSING FROM
THE NORTH TO THE SOUTH OVER THE ISLANDS. AREAS ALONG THE NORTH
FACING SLOPES ON KAUAI OAHU AND MOLOKAI HAVE SCATTERED LOW
CLOUDS. BROKEN LOW CLOUDS FILL IN OVER THE NORTH SLOPES OF
HALEAKALA AND THE WEST MAUI MOUNTAINS. THE DEVELOPMENT OF SEA
BREEZES THIS AFTERNOON HAVE ALLOWED FOR BROKEN LOW CLOUDS TO BUILD
UP ALONG THE SOUTH AND WEST SLOPES OF HALEAKALA. LANAI HAS
SCATTERED TO BROKEN LOW CLOUDS. REMAINING AREAS ON THE SMALLER
ISLANDS HAVE VERY FEW CLOUDS. OVER THE BIG ISLAND...SCATTERED TO
BROKEN LOW CLOUDS COVER THE NORTHEAST PORTION OF THE ISLAND FROM
UPOLU POINT TO HILO. THE PUNA AND KAU DISTRICTS HAVE OVERCAST LOW
CLOUDS BUILT UP. THE REST OF THE BIG ISLAND HAS FEW CLOUDS...
INCLUDING THE SUMMITS. THE TAIL END OF THE FRONT MENTIONED ABOVE
IS APPROXIMATELY 175 MILES SOUTHEAST OF SOUTH POINT HAWAII.
