AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
936 AM HST SAT JUN 22 2013

.SYNOPSIS...
MODERATE TO LOCALLY FRESH TRADE WINDS WILL CONTINUE THROUGH
MONDAY...THEN DIMINISH INTO NEXT WEEK. LOW CLOUDS AND SHOWERS WILL
FAVOR WINDWARD AND MAUKA AREAS...ESPECIALLY DURING NIGHTS AND
MORNINGS. THE GUSTY TRADES MAY ALSO CARRY A FEW SHOWERS OVER TO
LEEWARD SIDES OF THE SMALLER ISLANDS. THE LEEWARD BIG ISLAND WILL
HAVE AFTERNOON AND EVENING CLOUDS WITH EMBEDDED SHOWERS. WISPY HIGH
CLOUDS WILL STREAM OVER THE STATE THROUGH SUNDAY.

&&

.DISCUSSION...
HIGH PRESSURE REMAINS THE CONSTANT SUMMERTIME FEATURE TO THE NORTH
OF THE STATE...PROVIDING BREEZY TRADE WINDS THROUGH MONDAY.
SHOWERS WILL CONTINUE TO PUSH INTO THE WINDWARD SLOPES WITH AN
OCCASIONAL SHOWER PUSHING LEEWARD OVER THE SMALLER ISLAND
MOUNTAINS. AN UPPER LEVEL TROUGH CURRENTLY OVER THE STATE WILL
PULL UP SOME CIRRUS FROM THE SOUTH BRINGING SOME INCREASED COLOR
TO OUR SUNRISE/SUNSETS. THE WISPY HIGH CLOUDS WILL LAST THROUGH
THE WEEKEND AS THE UPPER TROUGH PUSHES OFF TO THE NORTH.

THERE IS SOME ANOMALOUS WEATHER OVER THE NORTHERN PACIFIC AS OUT-
OF-SEASON LOW PRESSURES MOVE EAST TOWARD THE MAINLAND. WHILE THESE LOWS
DIVE INTO THE NORTHWEST US/CANADIAN COAST...THEY WILL PUSH THE HIGH
PRESSURE CONTROLLING OUR TRADES WESTWARD OVER THE NEXT FEW DAYS. THE
WESTWARD PUSH WILL TURN OUR WINDS FROM THE CURRENT EASTWARD FLOW TO
A NORTHEASTERLY DIRECTION. LOWER PRESSURES FROM THE NORTH WILL ALSO
WEAKEN THE SUBTROPICAL HIGH...DROPPING TRADE WIND SPEEDS TO
MODERATE AS THEY TURN NORTHEASTERLY TUESDAY.

WINDWARD SHOWERS WILL CONTINUE THROUGH THE FORECAST PERIOD WITH
NIGHTTIME MAXIMA AND DAYTIME MINIMA...AND LEEWARD LOCATIONS WILL
SEE AN OCCASIONAL SHOWER. THERE WILL BE A DECREASE IN SHOWER
ACTIVITY AS THE WINDS TURN NORTHEASTERLY MONDAY AND TUESDAY. LOW
LEVEL MOISTURE WILL BE AT A MINIMUM AS DRIER AIR PUSHES OVER THE
STATE. WEDNESDAY...MOISTURE LEVELS WILL INCREASE FROM THE NORTH AS
AN OLD FRONTAL BOUNDARY REACHES KAUAI...AND AN UPTICK IN SHOWERS
IS EXPECTED OVER KAUAI AND OAHU LATE WEDNESDAY INTO EARLY FRIDAY.
THE BOUNDARY IS NOT FORECAST TO REACH MAUI COUNTY OR THE BIG
ISLAND...AND LIMITED WINDWARD SHOWERS WILL CONTINUE OVER THOSE
ISLANDS.

&&

.AVIATION...
CURRENT EPISODE OF PERSISTENT TRADE WINDS PUSHING NUMEROUS THOUGH
RANDOMLY SPACED PARCELS OF SHOWERY LOW CLOUDS THROUGH THE HAWAIIAN
ISLANDS. THOUGH VFR CONDITIONS SHOULD PREVAIL AT THE TAF SITES...
BRIEF MVFR VIS/CIG CONDITIONS WILL AFFECT WINDWARD AREAS WHICH
INCLUDE PHLI AND PHTO.

AIRMET TANGO WAS POSTED EARLIER THIS MORNING FOR LOW LEVEL
TURBULENCE SW THROUGH W OF MOUNTAIN RANGES OF ALL ISLANDS DUE TO
THE STRENGTHENING OF THE TRADE WINDS OVERNIGHT ACROSS THE STATE.

THE TYPICAL WINDY WATERS AROUND THE BIG ISLAND AND MAUI COUNTY.
