AS WAS THE CASE LAST EVENING...LOW CEILINGS APPEAR TO BE MAINLY
AFFECTING NORTHERN AND EASTERN SECTIONS OF THE ISLES THIS EARLY
MORNING.  MAUI AND THE BIG ISLAND ARE SEEING THE MOST BROKEN TO
OCCASIONALLY OVERCAST LOW CLOUDS...GENERALLY BELOW 7000 FEET...
INCLUDING OVER SOUTHERN AND WESTERN AREAS OF EACH ISLE.  SKIES ARE
CLEAR TO PARTLY CLOUDY ELSEWHERE.  LOW CLOUD MOTION IS FROM THE
SOUTH TO SOUTHWEST AT 15 TO 20 MPH STATEWIDE.

IN THE ADJACENT COASTAL WATERS...CLEAR TO SCATTERED CONDITIONS
EXIST SOUTHWEST CLOCKWISE THROUGH EAST OF KAUAI...WEST CLOCKWISE
THROUGH NORTH OF OAHU...SOUTH AND SOUTHWEST FROM LANAI...AND
SOUTHEAST AND SOUTH OF THE BIG ISLAND.  OTHERWISE...SKIES ARE BROKEN
TO OVERCAST WITH LOW CLOUDINESS.

A WEAK FRONT HAS BEEN DISSIPATING NORTHEAST OF THE STATE.  ANOTHER
WEAK FRONT HAS DEVELOPED NORTH OF THE ISLANDS AND HAS BEEN HEADING
EAST AND NORTHEAST AT 10 TO 15 MPH.  MUCH OF THE LOW CLOUDINESS WITH
THIS SECOND BOUNDARY IS HIDDEN BELOW A SWATH OF HIGH CLOUDS
ASSOCIATED WITH A JET STREAM...THOUGH MOST OF THE LOW CLOUDS ARE
LOCATED NORTH OF 23N.

AS ALLUDED TO ABOVE...A JET STREAM IS NORTHWEST AND NORTH OF THE
