HAWAIIAN ISLANDS SATELLITE INTERPRETATION MESSAGE
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
0030 UTC MON JUL 06 2015

BASED ON DATA THROUGH 0000 UTC JULY 06 2015

A WEAK UPPER LOW ABOUT 510 MILES NORTHEAST OF HILO WAS MOVING
SOUTH AROUND 10 MILES AN HOUR THIS AFTERNOON.  NO SIGNIFICANT
WEATHER WAS ATTRIBUTED TO THE LOW WHICH WAS PRODUCING ONLY A FEW
TUFTS OF CIRRUS JUST EAST OF ITS CENTER.

MEANWHILE...HIGH PRESSURE IN THE UPPER ATMOSPHERE SAT BETWEEN 20N
AND 30N FROM THE HAWAIIAN ISLANDS OUT TO THE INTERNATIONAL DATE
LINE.  A FAIRLY STRONG NORTHERLY WIND FLOW OVER THE ISLANDS WAS
KEEPING THE AIR MASS ON THE STABLE SIDE ACROSS THE STATE.

PATCHY SCATTERED CUMULUS CLOUDS WERE COMMON AROUND THE ISLAND CHAIN
THIS AFTERNOON.  THE LOW CLOUDS NEARBY WERE MOVING MAINLY TOWARD
THE WEST AT BETWEEN 10 AND 15 MILES AN HOUR.

AT 2 PM...CLOUD BUILD UPS WERE PRODUCING CLOUDY TO MOSTLY CLOUDY
SKIES OVER THE WEST HALF OF THE BIG ISLAND.  THE EAST HALF WAS
PARTLY TO MOSTLY CLOUDY.  THE OTHER ISLANDS WERE MOSTLY SUNNY WITH
JUST SOME SMALL AREAS MAINLY OVER THE MOUNTAINS AND LEEWARD SECTIONS.

A STATIONARY FRONTAL BOUNDARY SAT WELL NORTHWEST OF THE AREA.  THE
50 TO 60 MILES WIDE FRONTAL 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 MAINLY BETWEEN 11000 AND 13000
FEET HIGH.

PATCHES OF LOW CLOUDS NORTH OF 24N BETWEEN THE FRONT AND 160W WERE
MOVING NORTHWARD.  THIS WAS DUE TO THEIR BEING SITUATED BETWEEN THE
FRONT AND A SURFACE RIDGE EXTENDING THROUGH 30N 153W TO 24N 160W.
