HAWAIIAN ISLANDS SATELLITE INTERPRETATION MESSAGE
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.
