HAWAIIAN ISLANDS SATELLITE INTERPRETATION MESSAGE
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
1200 UTC FRI DEC 19 2014

BASED ON DATA THROUGH 1130 UTC DECEMBER 19 2014

AS WAS THE CASE LAST EVENING...LOW CEILINGS...SOME WITH ACCOMPANYING
SHOWERS...HAVE BEEN MAINLY LOCATED IN WINDWARD AND MAUKA AREAS ON
THE INDIVIDUAL ISLANDS.  AND ON THE SMALLER ISLES AND IN WEST
MAUI...BROKEN LOW CLOUDS HAVE BEEN MOVING OVER LEEWARD SECTIONS FROM
TIME TO TIME AS WELL.  LOW CLOUD MOVEMENT IS FROM THE EAST BETWEEN
20 AND 25 MPH ACROSS THE ALOHA STATE THIS EARLY MORNING.

BROKEN TO OCCASIONALLY OVERCAST LOW CLOUDINESS IS PREVALENT IN THE
WATERS SURROUNDING KAUAI AS OF BULLETIN TIME.  SCATTERED TO BROKEN
SHOWERY LOW CLOUDS ARE NORTH CLOCKWISE THROUGH SOUTH OF THE BIG
ISLAND...WHILE HIGH CLOUDS ARE ALSO GENERATING CEILINGS SOUTH OF THE
ISLE.  SKIES ARE OTHERWISE CLEAR TO SCATTERED OVER THE ADJACENT
COASTAL WATERS.

THE AXIS OF A JET STREAM SOUTH OF THE STATE IS GENERALLY ORIENTED
WEST-TO-EAST...AND...AS A WHOLE...HAS BEEN PUSHING STEADILY NORTH
OVER THE PAST SEVEN HOURS.  ROUGHLY SPEAKING...IT IS CURRENTLY ALONG
A LINE FROM 15N170W TO 17N160W TO 17N150W TO 12N140W.  THE JET IS
CARRYING A SWATH OF BROKEN TO OVERCAST HIGH CLOUDS...WITH SOME
ELEMENTS BEING JUST SOUTH OF THE BIG ISLAND...AS ALLUDED TO IN THE
SECOND PARAGRAPH.

CONVECTION IS WEAK AND SPORADIC ALONG THE INTERTROPICAL CONVERGENCE
ZONE FAR SOUTH OF HAWAII.  BETWEEN 140W AND THE DATE LINE AT 180...
MOST OF THE SHOWERS AND ISOLATED THUNDERSTORMS HAVE BEEN OCCURRING
FROM 03N TO 08N.

NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
0030 UTC FRI DEC 19 2014

BASED ON DATA THROUGH 0000 UTC DECEMBER 19 2014

REGIONAL SATELLITE IMAGERY SHOWS VARYING AMOUNTS OF LOW CLOUDS...
INCLUDING SHOWERY CUMULUS /CU/ AND STABLE STRATOCUMULUS /SC/...
MOVING OVER THE ISLANDS FROM THE EAST. SHOWERY CU ARE IN GREATER
CONCENTRATION OVER KAUAI AND OAHU AND ADJACENT WATERS...WHERE THEY
ARE BROKEN TO OVERCAST...WITH SCATTERED TO LOCALLY BROKEN LOW
CLOUDS OVER WINDWARD WATERS EAST OF MAUI AND THE BIG ISLAND. IN
ADDITION...RELATIVELY SMALL PATCHES OF BROKEN TO OVERCAST HIGH
CLOUDS HAVE RECENTLY DEVELOPED NEAR KAUAI AND OAHU...ASSOCIATED WITH
A WEAK TROUGH ALOFT MOVING SOUTHEAST OVER THE AREA.

MOSTLY CLOUDY SKIES PREVAIL OVER KAUAI AND OAHU AS SHOWERY CU MOVE
ASHORE OVER THE WINDWARD SIDES...AND SPREAD LEEWARD WITH THE FAIRLY
STRONG TRADE WINDS...WHICH ARE CARRYING LOW CLOUDS TOWARD THE WEST
AT SPEEDS NEAR 27 MPH. IN MAUI COUNTY...BROKEN TO OVERCAST SC AND CU
ARE BANKED ALONG THE LOWER PORTIONS OF THE WINDWARD SLOPES...WITH
SCATTERED LOW CLOUDS OVER LEEWARD AREAS. ONE EXCEPTION IS SOUTHWEST
MAUI NEAR ULUPALAKUA...WHERE BROKEN TO OVERCAST SC LINE THE LOWER
LEEWARD SLOPES OF HALEAKALA. THE CENTRAL VALLEY AND THE SUMMIT OF
HALEAKALA ARE UNDER MOSTLY SUNNY SKIES. ON THE BIG ISLAND...INTERIOR
AND UPSLOPE PORTIONS ARE UNDER SUNNY SKIES...WITH SCATTERED TO
LOCALLY BROKEN SC AND CU LINING THE SLOPES ABOVE HILO TOWN. BROKEN
TO OVERCAST SC ARE SEEN OVER THE NORTHEAST AND NORTHWEST SIDES OF
THE ISLAND...FROM HONOKAA TO UPOLU TO NEAR WAIKOLOA VILLAGE RESORT.

THE LOW CLOUD FIELD NEAR THE ISLANDS CONTINUES TO BE DOMINATED BY
SHOWERY CU ELEMENTS...WITH A MIX OF STABLE SC AND SHOWERY CU
PREVAILING ELSEWHERE ACROSS THE TROPICAL CENTRAL NORTH PACIFIC.
WATER VAPOR IMAGERY SHOWS THE ISLANDS WELL SOUTH OF THE POLAR
JET...WHICH IS LOCATED NORTH OF THE AREA NORTH OF 34N...WITH A
RELATIVELY STAGNANT FLOW ALOFT OVER THE MAIN HAWAIIAN
ISLANDS. A WEAK NORTHEAST TO SOUTHWEST ORIENTED TROUGH ALOFT IS
LOCATED NEAR KAUAI...AND IS MOVING TOWARD THE SOUTHEAST. THIS IS THE
FEATURE THAT IS RESPONSIBLE FOR THE PATCHY HIGH CLOUDS NEAR KAUAI
AND OAHU. A LARGE HIGH ALOFT IS CENTERED WEST OF THE DATE LINE NEAR
20N170E...AND AN ASSOCIATED RIDGE ALOFT EXTENDS NORTHEASTWARD OVER
MIDWAY ATOLL AND THE NORTHWESTERN HAWAIIAN ISLANDS.

CLOUDS PREVAIL FROM JUST NORTH OF HILO TO NEAR VOLCANO...WITH MOSTLY
SUNNY SKIES...AND FEW TO NO LOW CLOUDS...ELSEWHERE OVER THE ISLAND.
