AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE HONOLULU HI
715 AM HST FRI DEC 25 2015

.SYNOPSIS...
GUSTY TRADE WINDS ARE EXPECTED THROUGH THE HOLIDAY WEEKEND AS A NEW
SURFACE HIGH PASSES NORTH OF THE STATE. EXPECT THE BLUSTERY TRADES
TO BRING INCREASING LOW LEVEL MOISTURE INTO THE ISLANDS...WHICH WILL
CAUSE ABUNDANT LOW CLOUDS AND SHOWERS THIS WEEKEND. THE WET AND WINDY
TRADE WEATHER PATTERN WILL FOCUS MOST OF THE RAINFALL OVER WINDWARD
AND MAUKA AREAS...BUT THE STRONG TRADES WILL LIKELY TRANSPORT SOME
SHOWERS OVER LEEWARD SECTIONS OF THE SMALLER ISLANDS.

&&

.UPDATE...
A BATCH OF SHOWERS EMBEDDED IN THE TRADE FLOW WILL BE AFFECTING THE
WESTERN ISLANDS TODAY...ESPECIALLY KAUAI. SO THE ZONES HAVE UPDATED
REGARDING THE POPS. THE POPS WERE RAISED TO LIKELY FOR THE INTERIOR
AND MTN AREAS OF THE ISLAND FOR THE REST OF TODAY. ON OAHU...RAISED
THE POPS FOR MOST OF THE ISLAND FOR THIS MORNING...RANGING BETWEEN
SCATTERED AND LIKELY. KEPT THE POPS MOSTLY IN THE SCATTERED RANGE
FOR THIS AFTERNOON. THE POPS FOR WINDWARD MOLOKAI WERE LOWERED FOR
THIS MORNING THANKS TO DRY SLOT. FINALLY...ADDED SOME CLOUD COVER
FOR THE CENTRAL PART OF THE KONA COAST THIS MORNING.

&&

.DISCUSSION...
THE WESTERN END OF AN EAST-NORTHEAST TO WEST-SOUTHWEST ORIENTED
SURFACE RIDGE IS LOCATED ABOUT 450 MILES NORTH-NORTHEAST OF HONOLULU.
A FRONT LOCATED SLIGHTLY MORE THAN 355 MILES NORTHWEST OF LIHUE IS
RAPIDLY ERODING THE WESTERN EDGE OF THIS RIDGE AS IT MOVES EASTWARD AT
ABOUT 20 MPH. THIS FRONT IS NOT EXPECTED TO REACH THE ISLANDS. A NEW
1031 MB SURFACE HIGH BEHIND THE FRONT IS LOCATED NEAR 33N 180W. THIS
HIGH IS MOVING RAPIDLY EASTWARD AND IS CAUSING THE PRESSURE GRADIENT
TO INCREASE ACROSS THE ISLANDS. AS A RESULT...OUR TRADE WIND SPEEDS
ARE ALREADY STRENGTHENING SIGNIFICANTLY COMPARED WITH THE PAST FEW
DAYS.

ALOFT...MID TO UPPER LEVEL RIDGING IN THE VICINITY OF THE ISLANDS IS
MAINTAINING RELATIVELY STABLE ATMOSPHERIC CONDITIONS ACROSS THE
REGION. THE TRADES ARE TRANSPORTING PATCHES OF SCATTERED TO BROKEN LOW
CLOUDS WITH EMBEDDED SCATTERED SHOWERS INTO THE ISLANDS BASED ON
SATELLITE IMAGERY AND RADAR REFLECTIVITY DATA. MOST OF THE LOW CLOUDS
AND SHOWERS ARE AFFECTING WINDWARD AND MAUKA AREAS. BUT SOME SHOWERS
ARE REACHING LEEWARD SECTIONS OF SOME OF THE SMALLER ISLANDS. THERE ARE
ALSO LOW CLOUDS AND SHOWERS IN THE VICINITY OF THE KONA SIDE OF THE
BIG ISLAND.

THE FORECAST MODELS SHOW THAT THE NEW SURFACE HIGH WILL BE ALMOST DUE
NORTH OF THE ISLANDS BY EARLY SATURDAY MORNING. THIS WILL CAUSE THE
TRADE WINDS TO CONTINUE TO STRENGTHEN...AND WIND ADVISORIES MAY BE
REQUIRED FOR SOME OF THE TYPICALLY WINDY LAND AREAS STARTING LATER
TONIGHT OR SATURDAY. AT THE SAME TIME...AN UPPER LEVEL TROUGH
MOVING IN FROM THE NORTHWEST IS EXPECTED TO BE ABOVE THE ISLANDS...
WHILE A MID-LEVEL TROUGH PUSHES IN FROM THE EAST. THESE TROUGHS ALOFT
WILL DESTABILIZE THE ATMOSPHERE AND CAUSE THE INVERSION TO WEAKEN.
THESE RELATIVELY UNSTABLE ATMOSPHERIC CONDITIONS WILL ALLOW THE LOW
LEVEL MOISTURE BEING TRANSPORTED INTO THE ISLANDS BY THE TRADES TO
PRODUCE A WET TRADE WIND WEATHER PATTERN THIS WEEKEND. MOST OF THE
LOW CLOUDS AND TRADE SHOWERS WILL REMAIN FOCUSED ALONG WINDWARD AND
MAUKA AREAS...BUT THE GUSTY TRADES WILL CARRY SOME SHOWERS OVER TO
LEEWARD SECTIONS OF SOME OF THE SMALLER ISLANDS. NOTE THAT THE COOLER
TEMPERATURES ALOFT AND LACK OF A SIGNIFICANT LOW LEVEL TRADE WIND
INVERSION MIGHT RESULT IN THE DEVELOPMENT OF A WINTER WEATHER PATTERN
ON THE BIG ISLAND SUMMITS THIS WEEKEND. IT IS TOO EARLY TO DETERMINE
WHEN THIS MIGHT OCCUR...BUT IT MAY BE POSSIBLE STARTING AS EARLY AS
LATE TONIGHT OR SATURDAY.

AS THE HIGH CONTINUES TO SHIFT EASTWARD LATER THIS WEEKEND...THE
BLUSTERY WET TRADE WIND WEATHER PATTERN WILL REMAIN IN PLACE THROUGH
SUNDAY. HOWEVER...AS THE HIGH CONTINUES TO PUSH EASTWARD FROM SUNDAY
NIGHT THROUGH MONDAY...THE TRADE WIND SPEEDS WILL DIMINISH EARLY
NEXT WEEK. IN FACT...A NEW SURFACE FRONT MOVING IN FROM THE NORTHWEST
IS EXPECTED TO CAUSE THE SURFACE RIDGE ASSOCIATED WITH THE SURFACE
HIGH TO SHIFT DOWN CLOSER TO THE ISLANDS. THIS WILL CAUSE TRADE WIND
SPEEDS TO DRAMATICALLY DECREASE...AND WINDS MAY BECOME LOCALLY LIGHT
AND VARIABLE STARTING LATE TUESDAY OR WEDNESDAY. AT THE SAME TIME...
A MID-LEVEL RIDGE IS EXPECTED TO MOVE OVER THE ISLANDS FROM THE WEST.
THE ARRIVAL OF THIS FEATURE WILL LIKELY USHER IN A PERIOD OF STABLE
ATMOSPHERIC CONDITIONS. THIS STABILITY COMBINED WITH THE LIGHT AND
VARIABLE WIND REGIME WOULD LIKELY LEAD TO A DECREASE IN CLOUD COVER
AND SHOWERS DURING THE MIDDLE OF NEXT WEEK. NOTE THAT THERE IS A
POSSIBILITY OF A DIURNAL LAND AND SEA BREEZE PATTERN DEVELOPING BY
WEDNESDAY...AND CONTINUING THROUGH NEXT THURSDAY.

&&

.AVIATION...
AIRMET TANGO WILL LIKELY BE REQUIRED FOR TEMPO MODERATE LOW LEVEL
TURBULENCE LEEWARD OF THE MOUNTAINS ON ISLANDS STARTING LATER TODAY.

LOW CLOUDS AND SHOWERS WILL CONTINUE TO FAVOR THE WINDWARD AND
MOUNTAIN AREAS WITH BRIEF MVFR CIGS/VIS POSSIBLE. AS OF 1400Z THERE
ARE NO AIRMETS POSTED FOR MOUNTAIN OBSCURATION...BUT THERE IS A
POSSIBILITY THAT AIRMET SIERRA MAY BE NEEDED FOR THE HIGHER TERRAIN
OVER WINDWARD SIDES OF SOME OF THE ISLANDS LATER TODAY OR TONIGHT.

&&

.MARINE...
A SCATTEROMETER PASS FROM THURSDAY EVENING SHOWED STRONG TRADE WINDS
OVER THE COASTAL WATERS ACROSS THE EASTERN HALF OF THE STATE...WITH
WINDS OF UP TO 30 KT ALREADY OCCURRING IN THE ALENUIHAHA CHANNEL. AS
A RESULT...THE SMALL CRAFT ADVISORY /SCA/ IS NOW IN EFFECT FOR MOST
HAWAIIAN WATERS. THE SCA WILL BE EXPANDED TO INCLUDE ALL HAWAIIAN
WATERS FROM TONIGHT THROUGH THIS WEEKEND AS THE TRADE WINDS CONTINUE
TO STRENGTHEN. THE CURRENT FORECAST ALSO INDICATES THAT A GALE
WARNING WILL LIKELY BE ISSUED FOR THE ALENUIHAHA CHANNEL LATER TODAY
OR TONIGHT.

AS THE TRADE WINDS INCREASE...EXPECT SURF TO BUILD ALONG EAST FACING
SHORES. SURF IS EXPECTED TO REACH THE HIGH SURF ADVISORY CRITERIA
ALONG EAST FACING SHORES THIS WEEKEND. SMALL TO MODERATE NORTHWEST
SWELLS WILL MAINTAIN BELOW AVERAGE SURF ALONG NORTH AND WEST FACING
SHORES OF THE SMALLER ISLANDS THROUGH SATURDAY. A LARGER NORTHWEST
SWELL ARRIVING SUNDAY IS EXPECTED TO PEAK SUNDAY NIGHT. THE RESULTING
SURF MAY REACH THE HIGH SURF ADVISORY CRITERIA ALONG MOST NORTH
AND WEST FACING SHORES OF THE SMALLER ISLANDS. THIS SWELL WILL
GRADUALLY DECLINE MONDAY. FINALLY AN OUT OF SEASON SOUTH SWELL
IS FORECAST TO PRODUCE A BUMP IN SURF ALONG SOUTH FACING SHORES OF
THE ISLAND CHAIN THIS WEEKEND.
