MORRISON

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
1003 AM HST TUE DEC 2 2014

.SYNOPSIS...
FRESH TRADE WINDS TODAY WILL GRADUALLY SUBSIDE TO MODERATE LEVELS
THIS EVENING THROUGH WEDNESDAY...AS HIGH PRESSURE WEAKENS NORTH
OF THE STATE. MODERATE TRADES WILL THEN CONTINUE THURSDAY THROUGH
THE END OF THE WEEK. MOST RAINFALL WILL REMAIN FOCUSED ACROSS
WINDWARD AND MAUKA AREAS...WITH SOME PASSING SHOWERS OVER LEEWARD
LOCATIONS.

&&

.DISCUSSION...
MOSTLY CLEAR SKIES THIS MORNING WILL TRANSITION TO MOSTLY CLOUDY
OVER WINDWARD AREAS THIS AFTERNOON AS CLOUDS UPSTREAM OF THE
ISLANDS PUSH INTO THE WINDWARD SLOPES. LIGHT TO MODERATE SHOWERS
WILL ACCOMPANY THE CLOUDS WITH INCREASING COVERAGE OVERNIGHT.
LEEWARD AREAS WILL CONTINUE WITH PARTLY CLOUDY SKIES AND ISOLATED
SHOWERS NEAR THE MOUNTAINS FOR THE SMALLER ISLANDS WHILE THE KONA
COAST OF THE BIG ISLAND WILL CONTINUE WITH A DIURNAL CYCLE OF
AFTERNOON CLOUDS AND CLEARING OVERNIGHT.

THE ATMOSPHERE REMAINS QUITE DRY AND STABLE WITH A LOW INVERSION
BASE BETWEEN 6 AND 7 THOUSAND FEET AND MINIMAL PRECIPITABLE WATER
TOTALS BETWEEN 0.8 AND 1 INCH. HOWEVER... WITH MOST OF THE
MOISTURE TRAPPED UNDER THE INVERSION... THE BREEZY TRADE WINDS AND
MOUNTAIN TERRAIN ARE PRODUCING A GOOD AMOUNT OF RAINFALL ALONG
SELECT WINDWARD SLOPES. WINDWARD RAIN GAGES ON KAUAI AND THE BIG
ISLAND DEPICT 24-HOUR TOTALS BETWEEN 0.25 TO 1.25 INCHES AMONG THE
HIGHER TOTALS. A SIMILAR WINDWARD FOCUSED RAINFALL PATTERN IS
EXPECTED THROUGH THE WEEK.

A 1023 MB HIGH PRESSURE LOCATED FAR NORTH OF THE ISLANDS IS
PROVIDING THE CURRENT BREEZY TRADE WINDS. THE HIGH WILL WEAKEN
OVER THE NEXT FEW DAYS AS A COLD FRONT PASSES NORTH OF THE HIGH
AND PUSHES IT EASTWARD. TRADE WINDS WILL WEAKEN TO MODERATE/FRESH LEVELS
BY WEDNESDAY WITH SHOWERS REMAINING FOCUSED OVER THE WINDWARD
SLOPES WITH A FEW REACHING LEEWARD LOCATIONS. DEW POINT
TEMPERATURES WILL REMAIN IN THE UPPER 50/S TO LOW 60/S THROUGH THE
WEEK KEEPING SENSIBLE WEATHER IN THE COMFORTABLE TO COOL RANGE.

THE GFS AND ECMWF HAVE COME INTO BETTER AGREEMENT FOR THE END OF
THE WEEK AND WEEKEND FORECAST. BOTH DEVELOP A BROAD UPPER TROUGH
TO THE WEST AND SWING THE TROUGH OVER THE NORTHERN ISLANDS
WEDNESDAY NIGHT. A SECOND WEAKER TROUGH PASSES OVERHEAD ON FRIDAY.
BOTH TROUGHS BRING COOLER AIR ALOFT WHICH WILL RAISE THE INVERSION
LEVEL. THIS IN TURN WILL ALLOW FOR MORE VERTICAL CLOUD GROWTH AND
THE POTENTIAL FOR HEAVIER SHOWERS. IT APPEARS THAT MODERATE TRADE
FLOW WILL CONTINUE AT THE SURFACE... BUT IT IS UNCLEAR IF THERE
WILL BE SUFFICIENT MOISTURE AND INSTABILITY TO SPARK ANY ENHANCED
TRADE SHOWERS OUTSIDE OF THE FAVORED WINDWARD SLOPES. THE
OFFICIAL FORECAST MAINTAINS A NORMAL TRADE WIND SHOWER PATTERN FOR
NOW. BOTH MODELS SHOW AN AN INCREASE IN HIGH CLOUDS OVER THE
ISLANDS FROM WEDNESDAY NIGHT THROUGH FRIDAY AS THE UPPER LEVEL
FEATURES PASS FROM WEST TO EAST.

&&

.AVIATION...
HAVE RECEIVED A NUMBER OF PIREPS OF MODERATE TURBULENCE ASSOCIATED
WITH THE SMALL JET NE OF THE STATE...INCLUDING ONE OVER THE WINDWARD
COASTAL WATERS. ISSUED AN AIRMET FOR MODERATE HIGH-LEVEL TURBULENCE
ASSOCIATED WITH THIS JET. 12Z GFS GUIDANCE SHOWS THIS FEATURE MOVING
EASTWARD AND WEAKENING THROUGH THE MORNING...SO THIS AIRMET WILL
LIKELY NOT LAST MUCH PAST THE AFTERNOON. THE AIRMET FOR LOW-LEVEL
TURBULENCE IN THE LEE OF THE MOUNTAINS REMAINS IN EFFECT FOR NOW.
18Z AMDAR SOUNDINGS FROM HNL STILL SHOW 25 KNOTS OF WIND BELOW THE
INVERSION...ALTHOUGH THE OVERALL TREND WITH THE RADAR VAD WIND
PROFILES HAS BEEN DOWNWARD OVERNIGHT THROUGH THE MORNING. AS
CONDITIONS ARE EXPECTED TO IMPROVE...HAVE UPDATED THE TIMING ON THE
LOW-LEVEL AIRMET TO INDICATE AN ENDING AFTER NOON.

ONLY A FEW CLOUDS ARE CURRENTLY LOCATED ALONG WINDWARD SECTIONS WITH
PRIMARILY VFR CONDITIONS. A REMNANT CLOUD BAND JUST NORTH OF THE
STATE IS CURRENTLY APPROACHING KAUAI/OAHU...AND WILL SPREAD ACROSS
MAUI COUNTY AND THE BIG ISLAND THROUGH THE AFTERNOON/EVENING
RESPECTIVELY. THIS SHOWERY BAND WILL BRING OCCASIONAL MVFR
CONDITIONS MAINLY TO WINDWARD SECTIONS.

&&

.MARINE...
A STORM SPINNING OFF THE NW US COAST CONTINUES TO SEND NNE SWELL
TOWARD THE ISLANDS. THE DATA FROM BUOY 51000 IS COMING IN
SPORADICALLY BUT TWO REPORTS THIS MORNINGS SHOW A 12 FOOT SWELL AT
15 SECONDS. THIS SWELL IS EXPECTED TO INCREASE STEADILY TODAY
THROUGH THE ISLANDS WITH WARNING LEVEL SURF EXPECTED FOR EAST
FACING SHORES TONIGHT AND WEDNESDAY...AND THEN DROPPING BACK TO
ADVISORY LEVELS FOR THURSDAY.

A WEST-NORTHWEST SWELL IS BRINGING LOW END ADVISORY LEVEL SURF TO
NORTH AND WEST SHORES OF KAUAI AND NORTH SHORES OF OAHU MOLOKAI
AND MAUI. SURF IS EXPECTED TO DROP BELOW ADVISORY LEVELS THIS
EVENING.

OTHERWISE...THE SMALL CRAFT ADVISORY REMAINS FOR ALL COASTAL WATERS.
FRESH TRADE WINDS WILL WEAKEN TO MODERATE LEVELS THROUGH WEDNESDAY.
COMBINED SEAS OF THE NNE AND WNW SWELLS PLUS WIND WAVES WILL KEEP
THE SCA UP FOR ALL COASTAL WATERS THROUGH AT LEAST WEDNESDAY.
