HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
725 AM EST SAT DEC 20 2014

VALID 00Z SUN DEC 21 2014 - 00Z SUN DEC 28 2014


A COLD FRONT IS SLATED TO SETTLE ACROSS THE HAWAI`IAN ISLANDS
MONDAY, WHEREUPON IT IS PROGGED TO STALL AND DEVELOP A CLOSED WAVE
NOT FAR FROM THE STATE--MOST LIKELY OFF TO THE NORTHEAST. THERE
HAS BEEN QUITE A BIT OF VARIABILITY IN THE MODELS AS TO WHERE THE
CLOSING OFF TAKES PLACE, AND OF COURSE, MUCH AND MORE DEPENDS UPON
HOW CLOSE THE EDDY FORMS--IF AT ALL--PARTICULARLY WITH REGARD TO
WIND AND RAIN. AS OF THE 00Z/20 DATA CYCLE OF THE USUALLY RELIABLE
ECMWF, THE CIRCULATION LOOKS FAR ENOUGH TO THE EAST TO SPARE THE
ISLANDS A DOUSING, INDICATING SHOWERS FOLLOWED BY GUSTY NORTHWEST
WINDS IN THE UPCOMING WEEK.
