AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
400 PM HST FRI MAR 28 2014

.SYNOPSIS...
AN UNSTABLE WEATHER PATTERN CAN BE EXPECTED OVER THE NEXT COUPLE OF
DAYS DUE TO A TROUGH OF LOW PRESSURE IN THE ISLAND VICINITY. LOCALLY
HEAVY RAINFALL AND SCATTERED THUNDERSTORMS CAN BE EXPECTED THROUGH
SATURDAY NIGHT. WINDS WILL BE RATHER LIGHT WITH LAND AND SEA BREEZES
EXPECTED OVER MANY AREAS THOUGH LOCALLY GUSTY WINDS MAY OCCUR NEAR
NEAR THUNDERSTORMS. HIGH PRESSURE WILL BUILD IN NORTH OF THE
AREA EARLY NEXT WEEK WITH TRADE WINDS RETURNING. CLOUDS AND PASSING
SHOWERS WILL THEN FAVOR WINDWARD AND MAUKA AREAS WITH SOME SHOWERS
ALSO POSSIBLE OVER LEEWARD AREAS AT TIMES.

&&

.DISCUSSION...
MOISTURE ASSOCIATED WITH A LOW LEVEL TROUGH LINGERS OVER AND AROUND
THE STATE. THIS IS CAUSING SOME LOCALLY HEAVY SHOWERS TO FALL IN
PLACES PORTIONS OF THE STATE INCLUDING THE ADJACENT COASTAL WATERS.

WATER VAPOR IMAGERY SHOWS A MID AND UPPER LEVEL TROUGH DIGGING DOWN
TO THE STATE FROM THE NORTHWEST. THE ATMOSPHERE WILL BECOME
INCREASINGLY UNSTABLE TONIGHT THROUGH SATURDAY NIGHT THUS SCATTERED
THUNDERSTORMS ARE IN THE FORECAST THROUGH SATURDAY AND POSSIBLY
INTO SATURDAY NIGHT WITH LOCALLY HEAVY RAINFALL POSSIBLE. A SPECIAL
WEATHER STATEMENT HAS BEEN ISSUED FOR THE POSSIBILITY OF LOCALLY
SEVERE THUNDERSTORMS MAINLY FOR TONIGHT AND SATURDAY.

THE LOW LEVEL TROUGH WILL WEAKEN AND MOVE OFF TO THE WEST SATURDAY
NIGHT AND SUNDAY AS A SURFACE HIGH BUILDS IN TO OUR NORTH. THIS WILL
CAUSE A GRADUAL INCREASE IN TRADE WINDS. THE MID AND UPPER LEVEL
TROUGH WILL ALSO WEAKEN BUT LINGER IN THE ISLAND VICINITY. THIS WILL
TEND TO PRODUCE A WET TRADE WINDS PATTERN ACROSS THE AREA. SHOWERS
EARLY NEXT WEEK WILL TEND TO FAVOR WINDWARD AND MAUKA AREAS BUT THE
TRADE WINDS WILL BE SUFFICIENTLY STRONG TO BLOW SOME SHOWERS OVER
LEEWARD AREAS AT TIMES.

&&

.AVIATION...
ONSHORE SEA BREEZES DEVELOPED AT MANY LOCATIONS AGAIN TODAY...BUT
WILL BEGIN TO WEAKEN AS WE APPROACH SUNSET. HOWEVER THE SURFACE
TROUGH NEARBY AND AN INCREASINGLY UNSTABLE AIRMASS WILL KEEP SHOWERS
GOING IN SOME LOCATIONS OVERNIGHT. CONDITIONS WILL BE PRIMARILY
VFR...ALTHOUGH OCCASIONAL MVFR CEILINGS AND VISIBILITIES ARE
EXPECTED IN SHOWERS. HEAVY RAIN AND THUNDERSTORMS ARE ALSO
POSSIBLE...AND IFR VISIBILITIES ARE EXPECTED IN THE HEAVIER SHOWERS.

WAVE CLOUDS ARE APPARENT WITHIN AN AREA OF HIGH CLOUDS SPREADING
ACROSS KAUAI. THIS LINES UP WITH A LAYER OF STRONG VERTICAL WIND
SHEAR OBSERVED IN THE 00Z KAUAI SOUNDING. WINDS INCREASE FROM 60
KNOTS AT FL275 TO 82 KNOTS AT FL295. SHEAR THIS STRONG /OVER 10
KNOTS PER 1000 FEET/ IS A INDICATOR FOR CLEAR AIR TURBULENCE. HAVE
ISSUED AN AIRMET FOR MODERATE HIGH-LEVEL TURBULENCE ACROSS THE
SMALLER ISLANDS...WITH AN OUTLOOK FOR THE BIG ISLAND AS THE UPPER
JET MOVES EAST ACROSS THE STATE.

&&

.MARINE...
THERE WILL BE A SERIES OF SMALL NORTH AND NORTHWEST SWELLS OVER THE
NEXT SEVERAL DAYS WITH A LARGER NORTHWEST SWELL EXPECTED WEDNESDAY
NIGHT AND THURSDAY. STRENGTHENING TRADE WINDS EARLY NEXT WEEK WILL
CAUSE AN INCREASE IN SHORT PERIOD CHOPPY SURF ALONG EAST FACING
SHORES. THE INCREASE IN TRADE WINDS MAY CAUSE WINDS AND SEAS TO
REACH SMALL CRAFT ADVISORY LEVELS OVER THE TYPICALLY WINDY WATERS
AROUND MAUI COUNTY AND THE BIG ISLAND.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
FLASH FLOOD WATCH THROUGH LATE SATURDAY NIGHT FOR ALL HAWAIIAN
ISLANDS.
