HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
803 AM EDT THU MAY 23 2013

VALID 00Z FRI MAY 24 2013 - 00Z FRI MAY 31 2013

A LOW FAR NORTHEAST OF THE STATE WILL CONTINUE TO LOSE INFLUENCE
AS UPPER RIDGING BUILDS TOWARD/NORTH OF THE HAWAIIAN ISLANDS.
HOWEVER...BLENDED PRECIPITABLE WATER LOOPS STILL SHOW A DEEP PLUME
OF MOISTURE LIFTED/CENTERED OVER THE WEST-CENTRAL ISLANDS THAT MAY
FUEL SOME LOCALLY HEAVY SHORT TERM DOWNPOURS IN A DISRUPTED TRADE
FLOW RAINFALL PATTERN.

ISLAND TRADES WILL RESUME FRIDAY AND PERSIST NEXT WEEK AS HIGH
PRESSURE SETTLES OVER THE ERN PACIFIC AND LATER REINFORCES/BRIDGES
TO THE NORTH OF THE STATE IN A PATTERN WITH LOCALLY MODERATE
TERRAIN ENHANCED WINDWARD SHOWERS...WITH MORE SCATTERED SHOWERS
ELSEWHERE.  A COMPOSITE OF MODEL GUIDANCE FAVORS DEEPER MOISTURE
POOLING/RAINFALL POTENTIAL BY MIDWEEK UNDER A MEAN WEAKNESS ALOFT
IN A PATTERN WITH NEAR AVERAGE PREDICTABILITY.
