THE LEADING EDGE OF FRONTAL CLOUD BAND WAS JUST INSIDE OF 100 MILES
WEST-NORTHWEST OF KAUAI EARLY THIS AFTERNOON.  THIS LEADING EDGE
STRETCHED THROUGH 30N 155W TO 24N 160W TO 19N 180E.  THE CLOUD BAND
WAS ABOUT 125 MILES WIDE SOUTH OF 25N BUT STEADILY WIDENED TO JUST
OVER 250 MILES ACROSS AT 30N LATITUDE AND TO NEARLY 600 MILES ACROSS
AT 40N.  THE CLOUD BAND WAS APPROACHING KAUAI AT 15 TO 20 MILES AN
HOUR.

THE BAND CONSISTED OF BROKEN TO OVERCAST LOW CLOUDS SOUTH OF 25N
LATITUDE AND MOSTLY OVERCAST LOW TO MID LEVEL CLOUDS BETWEEN 25N
AND 30N.  BEHIND THE FRONTAL BAND TO THE NORTHWEST...NUMEROUS
PATCHES AND SMALL CLUSTERS OF STABLE LOW CLOUDS WERE COMMON.

LOW CLOUDS SURROUNDING MUCH OF THE STATE THIS MORNING HAD DISSIPATED
BY AFTERNOON.  CURRENTLY VERY FEW CLOUDS WERE SEEN IN THE IMMEDIATE
VICINITY OF THE ISLANDS...EXCEPT FOR A LARGE CLUSTER OF BROKEN TO
OVERCAST CUMULUS CLOUDS SITTING ABOUT 25 MILES EAST OF THE BIG
ISLAND OR 80 MILES EAST OF MAUI.  THIS CLUSTER WAS NEARLY
STATIONARY.

AT 2 PM...SKIES WERE SUNNY TO MOSTLY SUNNY OVER OAHU...MOLOKAI AND
KAUAI.  HOWEVER...THERE WAS A SMALL CLUSTER OF CLOUDS OVER THE
SOUTHEAST PART OF KAUAI.  MAUI AND LANAI HAD SOME CLOUDY AREAS ALONG
THE SLOPES BUT THE MAJORITY OF THOSE TWO ISLANDS WERE SEEING SUNNY
SKIES ALOFT.  THE BIG ISLAND HAD THE MOST CLOUDS WITH PARTLY CLOUDY
TO MOSTLY CLOUDY CONDITIONS ALONG MOST OF ITS SLOPES.

THE TRADE WINDS HAD VACATED THE 50TH STATE SINCE FRIDAY AHEAD OF THE
APPROACHING FRONT.  NUMEROUS CLUSTERS OF BROKEN TO OVERCAST LOW
CLOUDS...A MIX OF STRATOCUMULUS AND CUMULUS CLOUDS...WERE COMMON
NORTHEAST OF THE STATE BETWEEN 20N AND 30N EAST OF 154W.  THOSE
CLOUDS BETWEEN 145W AND 154W WERE STREAMING NORTHWARD.  AND THOSE
CLOUDS BETWEEN 140W AND 145W WERE MOVING NORTHWESTWARD AHEAD OF THE
FRONT.  THE FEW LOW CLOUDS SEEN NEAR THE ISLANDS WERE SOMEWHAT
