HAWAIIAN ISLANDS SATELLITE INTERPRETATION MESSAGE
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
0530 UTC TUE FEB 09 2016

BASED ON DATA THROUGH 0500 UTC FEBRUARY 09 2016

AT 700 PM HST...SATELLITE IMAGERY SHOWED A COLD FRONT ENTERING THE
NORTHWEST SECTION OF THE DISCUSSION AREA WEST OF 160W AND NORTH OF
27N. BROKEN TO OVERCAST LAYERED CLOUDS WITHIN THIS AREA WERE
DEPICTED QUICKLY ADVANCING TOWARD THE EAST NORTH OF THE STATE
BETWEEN 145W AND 165W AND NORTH OF 25N. MOSTLY LOW CLOUDS WERE SHOWN
NEAR THIS FRONTAL BOUNDARY WEST OF 165W WITH MAXIMUM CLOUD TOPS
EXTENDING TO 10 TO 15 THOUSAND FEET.

A DIFFUSE BAND OF LOW CLOUDS ASSOCIATED WITH THE COLD FRONT THAT
MOVED THROUGH THE ISLANDS OVER THE PAST COUPLE OF DAYS CONTINUED TO
LINGER WELL EAST OF THE BIG ISLAND FROM 20N 140W TO 15N 150W. THIS
LINGERING PORTION OF THE CLOUD BAND WAS NEARLY STATIONARY WITH CLOUD
TOPS REMAINING AT 10 THOUSAND FEET OR LESS.

SCATTERED TO OVERCAST LOW-LEVEL CUMULUS CLOUDS WERE SHOWN TRACKING
TOWARD THE SOUTHWEST OVER AND SOUTH OF THE ISLANDS. THE BEST CLOUD
COVERAGE WAS DEPICTED OVER THE BIG ISLAND AND MAUI WHERE A LARGE
AREA OF STABLE STRATOCUMULUS CLOUDS WAS SHOWN. BROKEN TO OVERCAST
CONDITIONS WERE DEPICTED MAINLY ALONG THE NORTH AND NORTHEAST
SECTIONS OF MAUI AND THE ADJACENT WATERS TO THE NORTH. MOSTLY CLEAR
SKIES PREVAILED OVER MOLOKAI AND LANAI. THE BEST CLOUD COVERAGE OVER
OAHU WAS OCCURRING OVER THE WINDWARD SIDE NEAR KANEOHE AND KAILUA.
CLEAR CONDITIONS WERE SHOWN OVER KAUAI AND NIIHAU.

ISOLATED TOWERING CUMULUS CLOUDS WERE LOCATED WELL SOUTH OF THE
STATE NEAR AND ALONG THE ITCZ BETWEEN THE EQUATOR AND 5N FROM 140W
TO THE DATE LINE. DEBRIS OR SCATTERED HIGH CLOUDS WERE SHOWN LIFTING
NORTHWARD AND EASTWARD BETWEEN 6N AND 13N. MAXIMUM CLOUD TOPS
ASSOCIATED WITH THESE TOWERING CUMULUS CLOUDS EXTENDED TO NEAR 40
THOUSAND FEET.

NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
0030 UTC TUE FEB 09 2016

BASED ON DATA THROUGH 0000 UTC FEBRUARY 09 2016

THE MAIN HAWAIIAN ISLANDS REMAIN UNDER A VERY DRY AND STABLE
AIRMASS IN THE WAKE OF A COLD FRONT. SATELLITE DERIVED PRECIPITABLE
WATER VALUES ARE RUNNING AROUND 65 PERCENT OF NORMAL IN THE 0.6 TO
0.7 OF AN INCH RANGE...AND A LOW LEVEL RIDGE JUST NORTH OF KAUAI
BETWEEN 22N AND 23N IS DRIVING A NORTHEAST LOW LEVEL FLOW THAT IS
PRODUCING ONLY SCATTERED PATCHES OF VERY STABLE STRATOCUMULUS
CLOUDS. THE ONLY EXCEPTION IS AN AREA OF BROKEN LOW CLOUDS ALONG
THE SHELTERED LEEWARD SLOPES OF THE KAU AND SOUTH KONA DISTRICTS
OF THE BIG ISLAND.

THE ABOVE MENTIONED FRONT HAS MAINLY PUSHED EAST OF 140W...THOUGH
A NEARLY STATIONARY BAND OF BROKEN LOW CLOUDS ALONG 20N140W AND
17N144W MARK THE TRAILING EDGE OF THIS FEATURE. THE PARENT LOW OF
THE FRONT IS NORTH OF 30N...BUT IT CONTINUES TO TRIGGER A CLUSTER OF
SCATTERED LOW-TOPPED THUNDERSTORMS RISING TO 25000 FT NORTH OF 28B
EAST OF 144W. A TRAILING TROUGH RUNNING THROUGH THIS AREA IS ALSO
PRODUCING A 100 TO 200 MILE WIDE BAND OF BROKEN CUMULUS CLOUDS FROM
29N144W TO 25N156W. THIS FEATURE IS TRAVELING TOWARD THE EAST NEAR
25 MPH.

A DRY AND STABLE SOUTHWESTERLY LOW LEVEL FLOW DOMINATES OVER MOST
OF THE NORTHWEST HAWAIIAN ISLANDS...WHILE A FRONT IS SAGGING
SOUTHWARD OVER KURE AND MIDWAY ATOLLS. THE FRONT IS MARKED BY A
250 MILE-WIDE BAND OF OVERCAST LOW CLOUDS CENTERED ALONG 30N170W
AND 28N180 THAT IS MOVING TOWARD THE EAST-SOUTHEAST AROUND 40 MPH.

ELSEWHERE...LIGHT THUNDERSTORM ACTIVITY WITHIN THE ITCZ IS
CONFINED WELL SOUTH OF 10N.

1830 UTC MON FEB 08 2016

BASED ON DATA THROUGH 1800 UTC FEBRUARY 08 2016

THE MAIN HAWAIIAN ISLANDS LIE UNDER A DRY AND STABLE AIRMASS
BEHIND A FRONT THAT IS STALLING ABOUT 300 MILES SOUTHEAST OF THE
BIG ISLAND. LOW CLOUD MOTIONS IN THE FIRST VISIBLE SATELLITE IMAGES
OF THE DAY SHOW AN EASTWARD-MOVING SURFACE HIGH CENTERED ABOUT 250
MILES NORTHWEST OF KAUAI WITH A LOW LEVEL RIDGE EXTENDING EASTWARD
BETWEEN 22N AND 23N...AND RECENT POLAR ORBITER DATA SHOW
PRECIPITABLE WATER VALUES RUNNING ONLY ABOUT 65 PERCENT OF NORMAL.
AS A RESULT...VERY STABLE...SCATTERED TO LOCALLY BROKEN
STRATOCUMULUS CLOUDS WITH TOPS AROUND 3C...ABOUT 7500 FT...ARE
MOVING TOWARD THE SOUTH-SOUTHWEST OVER THE ISLANDS. THESE CLOUDS
ARE PILED UP ALONG NORTH AND NORTHEAST FACING SLOPES OF THE BIG
ISLAND...WITH ANOTHER CLUSTER OBSERVED ON NORTH SLOPES OF KAUAI.
ONLY SMALL PATCHES OF BROKEN LOW CLOUDS ARE FOUND ON OAHU...
MOLOKAI AND MAUI...WHILE LEEWARD SKIES ARE MOSTLY CLEAR.

THE FRONT THAT MOVED THROUGH THE ISLANDS IS MARKED BY A 150 TO 200
MILE WIDE BAND OF BROKEN TO OVERCAST LOW CLOUDS ALONG 24N140W TO
15N153W. ITS PARENT LOW IS CENTERED JUST NORTH OF THE AREA NEAR
33N146W AND IS LIFTING TOWARD THE NORTHEAST. AN AREA OF SCATTERED
THUNDERSTORMS WITH TOPS TO 30000 FT IS FOUND TO THE SOUTH OF THE
LOW IN THE AREA NORTH OF 28N BETWEEN 143W AND 149W. A STRONG JET
STREAM ALOFT ASSOCIATED WITH THE UPPER LEVEL TROUGH DRIVING THE
FRONT IS ALSO GENERATING A SHIELD OF BROKEN HIGH CLOUDS NORTH OF
26N BETWEEN 153W AND 163W.

ELSEWHERE...A DRY AND STABLE SOUTHWESTERLY LOW LEVEL FLOW PREVAILS
OVER THE NORTHWEST HAWAIIAN ISLANDS...AND LIGHT THUNDERSTORM
ACTIVITY WITHIN THE ITCZ IS CONFINED SOUTH OF 10N.

AT 200 AM HST...SATELLITE IMAGERY SHOWED THE COLD FRONT THAT MOVED
THROUGH THE ISLAND CHAIN OVER THE PAST 24 TO 36 HRS NOW WELL EAST OF
THE BIG ISLAND STRETCHING SOUTH AND SOUTHWEST FROM 30N 142W TO TO
20N 147W...THEN SOUTHWEST TO 12N 170W. BROKEN TO OVERCAST LAYERED
CLOUDS WERE LOCATED NORTH AND NORTHEAST OF 21N ALONG A CLOUD BAND
ASSOCIATED WITH THIS FRONT. ELSEWHERE...A BAND OF MOSTLY LOW-LEVEL
CUMULUS CLOUDS WAS DEPICTED...WHICH WAS BEGINNING TO BREAK UP AND
SCATTER OUT TOWARD THE SOUTHERN END OF THE BAND OR SOUTH AND
SOUTHEAST OF THE BIG ISLAND. THIS BAND OF CLOUDS WAS MOVING EAST AND
SOUTHEAST AWAY FROM THE HAWAIIAN ISLANDS.

SCATTERED TO BROKEN LOW-LEVEL CUMULUS CLOUDS WERE SHOWN TRACKING
SOUTH OVER THE STATE IN THE WAKE OF THE AFOREMENTIONED FRONTAL
BOUNDARY. A LARGER PATCH OF LOW CLOUDS WAS LEADING TO MOSTLY CLOUDY
CONDITIONS OVER THE HAMAKUA COAST OF THE BIG ISLAND. CLOUD TOPS
EXTENDED TO 10 TO 12 THOUSAND FEET WITH THESE CLOUDS.

SCATTERED TO BROKEN CUMULUS CLOUDS WERE DEPICTED WEST OF THE
PREVIOUSLY DISCUSSED FRONTAL BOUNDARY AND NORTH OF THE MAIN HAWAIIAN
ISLANDS BETWEEN 25N AND 30N FROM 145W TO 155W. THESE CLOUDS WERE
TRACKING EAST AND SOUTHEAST AT 30 TO 40 MPH. A FEW THUNDERSTORMS
WERE DEPICTED WITHIN THIS AREA NEAR 30N 150W WITH CLOUD TOPS TO 30
THOUSAND FEET.

ISOLATED THUNDERSTORMS WERE LOCATED WELL SOUTH OF THE STATE NEAR AND
ALONG THE ITCZ BETWEEN THE EQUATOR AND 5N FROM 140W TO THE DATE
LINE. DEBRIS OR SCATTERED HIGH CLOUDS ASSOCIATED WITH THESE STORMS
WERE SHOWN LIFTING NORTHWARD AND EASTWARD BETWEEN 7N AND 13N.

AT 700 PM HST...SATELLITE IMAGERY SHOWED THE COLD FRONT THAT MOVED
THROUGH THE ISLAND CHAIN OVER THE PAST 24 HRS NOW EAST OF THE BIG
ISLAND STRETCHING SOUTH AND SOUTHWEST FROM 30N 146W TO JUST EAST OF
THE BIG ISLAND...THEN SOUTHWEST TO 14N 162W. BROKEN TO OVERCAST
LAYERED CLOUDS WERE LOCATED NORTH AND NORTHEAST OF 23N ALONG A CLOUD
BAND ASSOCIATED WITH THIS FRONT. ELSEWHERE...A BAND OF MOSTLY LOW-
LEVEL CUMULUS CLOUDS WAS DEPICTED...WHICH WAS BEGINNING TO BREAK UP
AND SCATTER OUT TOWARD THE SOUTHERN END OF THE BAND OR SOUTH AND
SOUTHEAST OF THE BIG ISLAND. A GRADUAL MOTION TOWARD THE EAST WAS
DEPICTED WITH THIS BAND OVER THE PAST FEW HOURS.

SCATTERED LOW-LEVEL CUMULUS CLOUDS WERE SHOWN TRACKING SOUTH OVER
THE MAIN HAWAIIAN ISLANDS IN THE WAKE OF THE AFOREMENTIONED FRONTAL
BOUNDARY. HOWEVER...BROKEN TO OVERCAST PATCHES OF LOW CLOUDS TOWARD
THE BACK EDGE OF THE FRONTAL CLOUD BAND CONTINUED TO IMPACT THE
ISLANDS FROM MAUI TO THE BIG ISLAND...ESPECIALLY OVER THE ADJACENT
COASTAL WATERS NORTH AND EAST OF HANA AND THE HAMAKUA COAST. CLOUD
TOPS EXTENDED TO 10 TO 12 THOUSAND FEET WITH THESE CLOUDS.

SCATTERED TO BROKEN CUMULUS CLOUDS WERE DEPICTED WEST OF THE
PREVIOUSLY DISCUSSED FRONTAL BOUNDARY AND NORTH OF THE MAIN HAWAIIAN
ISLANDS BETWEEN 25N AND 30N FROM 149W TO 160W. THESE CLOUDS WERE
TRACKING SOUTHEAST AT 30 TO 40 MPH. A FEW THUNDERSTORMS WERE
DEPICTED WITHIN THIS AREA NEAR 30N FROM 150W TO 155W WITH CLOUD TOPS
TO 30 THOUSAND FEET.

SCATTERED TO NUMEROUS THUNDERSTORMS WERE LOCATED WELL SOUTH OF THE
STATE NEAR AND ALONG THE ITCZ BETWEEN THE EQUATOR AND 6N FROM 140W
TO THE DATE LINE. DEBRIS OR SCATTERED HIGH CLOUDS ASSOCIATED WITH
THESE STORMS WERE SHOWN LIFTING NORTHWARD AND EASTWARD BETWEEN 7N
