AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HONOLULU HI
731 AM HST WED FEB 11 2015

.UPDATE...
DOWNGRADED THE HIGH WIND WARNING FOR THE BIG ISLAND SUMMITS TO A
WIND ADVISORY BASED ON OBSERVATIONS AND MODEL GUIDANCE. ADJUSTED
SHORT AND MID-TERM FORECAST WINDS FOR THE BIG ISLAND SUMMITS.
SLIGHTLY INCREASED CHANCES FOR RAIN AND CLOUD COVER MAINLY FOR
KAUAI AND OAHU TODAY BASED ON RADAR AND SATELLITE IMAGERY.

&&

.SYNOPSIS...
DRY AND RELATIVELY COOL CONDITIONS WITH STABLE LOW CLOUDS WILL
PREVAIL OVER THE STATE THROUGH THURSDAY. LIGHT NORTHERLY WINDS WILL
INCREASE AND BECOME SOUTHWEST AGAIN BY FRIDAY. A FRONT WILL SPREAD
MODERATE RAIN ACROSS THE ISLANDS OVER THE WEEKEND. DRIER WEATHER
WILL RETURN BY EARLY NEXT WEEK.

&&

.PREV DISCUSSION.../ISSUED 400 AM HST WED FEB 11 2015/

THE WEAK FRONT ESSENTIALLY DISSIPATED OVER THE BIG ISLAND EARLIER IN
THE NIGHT...BUT STABLE STRATUS LAYERS REFORMED SHORTLY THEREAFTER.
COLD-AIR CUMULI ADVANCED OVER THE REST OF THE STATE. IN ANY CASE...
SHOWER ACTIVITY RAPIDLY DIMINISHED TO NEAR NOTHING...AND SHOULD
REMAIN SPARSE AT BEST THROUGH TODAY. ALOFT...THE MASSIVE GYRE OVER
THE NORTHEAST PACIFIC REMAINED IN PLACE...BUT THE TROUGH LOBE
SUPPORTING THE CURRENT FRONT ROTATED AWAY TOWARD THE NORTHEAST...
LEAVING SLIGHTLY HIGHER HEIGHTS OVER THE STATE THROUGH EARLY FRIDAY.
DESPITE THE DOME OF HIGH PRESSURE SPREADING SOUTHEAST OVER THE
ISLANDS NEAR THE SURFACE...THE COLD AIR MASS...AND EXTENSIVE STABLE
CLOUD COVER....WILL KEEP CONDITIONS ON THE COOL SIDE.

GUIDANCE AGREED REASONABLY WELL THAT BY LATE ON FRIDAY ANOTHER
TROUGH LOBE OF THE EAST PACIFIC MID-LEVEL VORTEX WILL ROTATE TOWARD
THE STATE...SUPPORTING THE APPROACH OF ANOTHER FRONT AT THE SURFACE.
IN GENERAL...THIS NEW FEATURE SHOULD FOLLOW THE PATTERN OF THE
RECENT ONE...WITH INCREASING SOUTHWESTERLY WINDS AHEAD OF THE
FRONT...AND THEN GRADUALLY DIMINISHING NORTHWESTERLIES BEHIND IT.
GUIDANCE PREDICTED SUBSTANTIAL PRECIPITABLE WATER TO ACCOMPANY THIS
NEW FRONT...IMPLYING THE POSSIBILITY OF MODERATE TO HEAVY RAIN. ON
THE OTHER HAND...THE OVERALL SIMILARITY TO THE LAST FRONT SUGGESTED
THAT GUIDANCE ONCE AGAIN OVERESTIMATED THIS POTENTIAL. LATER
SOLUTIONS NO DOUBT WILL BE INSTRUCTIVE...BUT FOR NOW THE RAIN EVENT
OVER THE WEEKEND LOOKED MARGINAL TO MODEST AT MOST. IN ANY CASE...
DRY...POSTFRONTAL CONDITIONS WITH LIGHT NORTHERLY TO NORTHEASTERLY
WINDS WILL PREVAIL AGAIN BY AROUND MONDAY.

&&

.AVIATION...
A DISSIPATING COLD FRONT NEAR THE BIG ISLAND WILL CONTINUE TO
PRODUCE ISOLATED MVFR CIGS AND MOUNTAIN OBSCURATION IN THAT AREA
THROUGH EARLY THIS MORNING. A DRIER AIRMASS WITH VFR CONDITIONS WILL
PREVAIL OVER THE REMAINDER OF THE STATE BEHIND THE FRONT.

AIRMET TANGO REMAINS IN EFFECT FOR TEMPO MODERATE TURBULENCE OVER
AND TO THE EAST OF THE MOUNTAINS ACROSS THE ENTIRE STATE. EXPECT
TURB TO CONTINUE THIS MORNING AS BRISK WESTERLY LOW/MID LEVEL FLOW
PERSISTS. CONDITIONS SHOULD IMPROVE THIS AFTERNOON.

&&

.MARINE...
A LARGE NORTHWEST SWELL WILL CONTINUE TO AFFECT MOST NORTH AND
WEST FACING SHORES OF THE STATE THROUGH AT LEAST THURSDAY. SURF
WILL REMAIN ABOVE THE WARNING THRESHOLD THROUGH THIS AFTERNOON.
THE WEST COMPONENT OF THE SWELL ALSO BROUGHT SURF TO THE WEST
COAST OF THE BIG ISLAND...AND SO A HIGH SURF ADVISORY WAS IN
EFFECT FOR THAT AREA.

A SMALL CRAFT ADVISORY /SCA/ ALSO WAS IN EFFECT FOR ALL HAWAIIAN
WATERS EXCEPT MAALAEA BAY...MAINLY FOR COMBINED SEAS.

&&
