AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
831 PM HST THU JAN 5 2012

.SYNOPSIS...
HIGH PRESSURE NORTHEAST OF THE ISLANDS WILL MAINTAIN LIGHT TO MODERATE
TRADE WINDS INTO NEXT WEEK. MOSTLY DRY WEATHER WILL PREVAIL...WITH
THE TRADES DELIVERING JUST A FEW BRIEF SHOWERS... MAINLY WINDWARD.

&&

.DISCUSSION...
CURRENT SATELLITE IMAGERY SHOWS MOSTLY CLEAR SKIES ACROSS THE
WESTERN PORTION OF THE STATE...WITH SCATTERED STABLE LOW CLOUDS
FILLING IN ON THE EASTERN SIDE. THE WATER VAPOR LOOP SHOWS A
BUILDING UPPER LEVEL RIDGE MOVING CLOSER TO THE ISLANDS FROM THE
WEST AND SOUNDINGS FROM THE AFTERNOON SHOW A VERY DRY AND STABLE
ATMOSPHERE OVER THE STATE. LIMITED WINDWARD RAINFALL CARRIED IN BY
MODERATE TRADE WINDS IS EXPECTED TONIGHT AND THROUGH THIS
WEEKEND...WHILE LEEWARD AREAS SHOULD STAY DRY. THE TRADES ARE
DRIVEN BY A SURFACE HIGH FAR NORTHEAST OF THE STATE...WITH A RIDGE
EXTENDING TO THE NORTH OF HAWAII.

THE UPPER LEVEL RIDGE OVER THE ISLANDS IS PROVIDING THE STABLE
ATMOSPHERE AND WILL ONLY INCREASE IN STRENGTH OVER THE WEEKEND
PREVENTING MUCH VERTICAL CLOUD GROWTH. THIS RIDGE WILL REMAIN IN
PLACE THROUGH WEDNESDAY OF NEXT WEEK. THE SURFACE RIDGE NORTH OF
THE STATE WILL FLUCTUATE IN LOCATION OVER THE NEXT SEVERAL DAYS
AS LOW PRESSURE SYSTEMS PASS THROUGH THE NORTH PACIFIC. A SLIGHT
WEAKENING IN THE TRADES IS EXPECTED THIS WEEKEND AS THE RIDGE
MOVES CLOSER TO THE ALOHA STATE...AND THEN BUMPS UP A NOTCH EARLY
NEXT WEEK AS THE RIDGE EDGES NORTH.

LONGER RANGE MODELS INDICATE STRONGER TRADES WILL PUSH A SHEAR
LINE OVER THE ISLANDS TOWARD THE END OF NEXT WEEK...BUT WILL
CONTINUE TO WATCH THIS FOR CHANGES IN TIMING.

&&

.AVIATION...
00Z-01Z ACARS SOUNDINGS OUT OF HONOLULU AND KAHULUI SHOW 25-30 KNOTS
OF WIND NEAR THE INVERSION HEIGHT. THIS IS A BIT STRONGER THAN RADAR
VAD WIND PROFILES AND THE 00Z SOUNDINGS...WHICH SHOW UP TO 20 KNOTS
IN THE MIXED LAYER. WE HAVE RECEIVED ONE PILOT REPORT OF LIGHT
TURBULENCE NEAR KAUAI THIS MORNING. WINDS ARE EXPECTED TO BE
SOMEWHAT LIGHTER ON FRIDAY...THEN WEAKEN FURTHER ON SATURDAY. WITH
THE LACK OF REPORTS TODAY AND WEAKENING WINDS EXPECTED...NO AIRMETS
FOR TURBULENCE ARE ANTICIPATED.

WITH THE DRY AIRMASS ACROSS THE STATE...VFR CONDITIONS WILL PREVAIL.
ONLY BRIEF MVFR CEILINGS ARE POSSIBLE ACROSS WINDWARD SECTIONS.

&&

.MARINE...
A HIGH SURF ADVISORY WILL REMAIN TONIGHT AND LIKELY BE DROPPED
IN THE MORNING AS THE NW SWELL CONTINUES TO DROP. A NEW WNW SWELL
WILL BRING AN INCREASE IN SURF ON SATURDAY...WITH PEAK HEIGHTS
JUST BELOW ADVISORY LEVELS. A SLIGHTLY LARGER NW SWELL ON SUNDAY
IS EXPECTED TO BRING ADVISORY LEVEL SURF TO MOST N AND W SHORES.

ALTHOUGH ON THE DECLINE...COMBINED SEAS WILL REMAIN AT OR ABOVE 10
FT MOST AREAS TONIGHT...DUE TO THE COMBINATION OF NW SWELL...WIND
WAVES...AND A SHORT-LIVED N SWELL. A SMALL CRAFT ADVISORY IS IN
EFFECT THROUGH TONIGHT.

&&

HIGH SURF ADVISORY UNTIL 6 AM HST FRIDAY FOR NORTH AND WEST
FACING SHORES OF NIIHAU KAUAI OAHU MOLOKAI MAUI AND THE BIG
