HAWAIIAN ISLANDS SATELLITE INTERPRETATION MESSAGE
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
1830 UTC SUN JUL 05 2015

BASED ON DATA THROUGH 1800 UTC JULY 05 2015

A WEAK UPPER LOW ABOUT 550 MILES NORTHEAST OF HILO WAS MOVING
SOUTHEAST AROUND 10 MILES AN HOUR.  NO SIGNIFICANT WEATHER WAS BEING
ASSOCIATED WITH THIS LOW AS IT SLOWLY MOVED FURTHER AWAY FROM THE
ISLANDS THIS MORNING.

MEANWHILE...A LARGE...UPPER LEVEL...HIGH PRESSURE REGION SAT NOT TOO
FAR NORTHWEST OF THE STATE.  THE NORTHERLY WIND FLOW ALOFT OVER THE
ISLANDS ON THE EAST SIDE OF THE HIGH PRESSURE AREA WAS KEEPING THE
AIR MASS FAIRLY STABLE ACROSS THE STATE.

GRADUALLY RETURNING TRADE WINDS WERE EVIDENT AS THE PATCHES OF
SCATTERED LOW CLOUDS NEAR THE ISLANDS WERE MOVING TOWARD THE WEST
NEAR KAUAI AND TOWARD THE WEST SOUTHWEST AROUND THE OTHER ISLANDS.
THE CLOUDS WERE MOVING ALONG AT 15 MILES AN HOUR BUT COULD INCREASE
IN SPEEDS A BIT AS THE DAY WEARS ON.

THERE WERE SOME SMALL CLUSTERS OF BROKEN LOW CLOUDS ALONG AND
IMMEDIATELY EAST OF THE WINDWARD COASTS OF THE BIG ISLAND.  AND ONE
CLUSTER WAS IN THE ALENUIHAHA CHANNEL.  OVER THE ISLANDS AND AROUND
THE REST OF THE STATE...SKIES WERE SUNNY TO MOSTLY SUNNY AT 8 AM.

A FRONT WAS NEARLY STATIONARY...STILL LINGERING OFF TO THE NORTHWEST
THIS MORNING.  THE NARROW...ROUGHLY 50 MILES WIDE CLOUD BAND WAS
CENTERED ALONG A LINE THROUGH 30N 168W TO 24N 175W TO BEYOND 23N
180E.  THE BROKEN TO OVERCAST LOW CLOUD BAND HAD TOPS FROM 10000 TO
AS MUCH AS 17000 FEET HIGH.  LOW CLOUDS IN AN AREA FROM 20N TO 30N
BEWTEEN 160W AND 168W WERE FLOWING NORTHWARD IN RESPONSE TO THE
PRESENCE OF THE FRONT.
