WATER VAPOR IMAGERY SHOWED A LARGE UPPER LEVEL LOW CENTERED FAR
NORTH OF THE STATE NEAR 36N 155W EARLY THIS AFTERNOON.  THE LOW WAS
MOVING NORTHWARD AT A STEADY PACE.  THE UPPER LEVEL WIND CIRCULATION
ALONG THE OUTSKIRTS OF THE LOW WAS OUT OF THE WEST NORTHWEST OVER
THE STATE THIS MORNING BUT HAS RECENTLY BECOME MORE FROM THE WEST.
A FEW SPRIGS OF CIRRUS CLOUDS WERE PASSING ABOUT 100 MILES NORTH OF
THE STATE...BETWEEN 23N 154W AND 27N 162W...WITHIN THE UPPER LEVEL
WIND FLOW.

THE UPPER LOW WAS GENERATING OVERCAST CLOUD LAYERS AND ISOLATED

FRONT EXTENDED THROUGH 30N 143W TO 25N 147W TO 15N 152W.  IT WAS
MOVING EAST AROUND 10 MILES AN HOUR.  THE FRONTAL CLOUD BAND WAS
ABOUT 300 MILES WIDE AT 30N LATITUDE BUT GRADUALLY NARROWED TO A
FINE LINE OF THUNDERSTORMS AT THE SOUTHERN TIP NEAR 15N.

NEAR THE HAWAIIAN ISLANDS...NUMEROUS PATCHES AND SMALL CLUSTERS OF
OF SCATTERED TO BROKEN LOW CLOUDS SURROUNDED KAUAI AND THE AREA TO
THE NORTH.  THE SOUTHERN EDGE OF THIS CLOUD MASS WAS OVER CENTRAL

THE BIG ISLAND.  THE CLOUDS WERE STREAMING SOUTHEASTWARD NEAR 12
MILES AN HOUR.

AT 2 PM...SKIES WERE MOSTLY CLOUDY OVER KAUAI.  OAHU HAD JUST ABOUT
AN EVEN MIX OF PARTLY CLOUDY...MOSTLY CLOUDY AND SUNNY SKIES SPREAD
AROUND THE ISLAND.  MAUI COUNTY WAS SUNNY OVER THE VAST MAJORITY OF
THE AREA...EXCEPT FOR A SMATTERING OF CLOUDS ALONG THE SOUTH COAST
OF MOLOKAI AND ALONG E3H SOUTHEAST COAST OF MAUI.  THE BIG ISLAND
HAD CLOUD CONDITIONS ALONG MUCH OF ITS SLOPES.  BUT THERE WAS ALSO
A GOOD AMOUNT OF SUNNY SKIES OVER THE WESTERN TWO THIRDS OF THAT
