HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
801 AM EDT MON AUG 31 2015

VALID 00Z TUE SEP 01 2015 - 00Z TUE SEP 08 2015

THE 31/00Z MODEL CYCLE WAS IN VERY GOOD AGREEMENT WITH THE NORTH
PACIFIC SYNOPTIC-SCALE FLOW PATTERN---AND HAS RESOLVED THE
FORECAST CHALLENGE ALONG 160W NEXT WEEKEND WITH THE VORTICITY
ENTRAINMENT OF `IGNACIO` INTO THE MID-LATITUDE WESTERLIES.
RECOMMEND A DAY 6-7 SOLUTION IN LINE WITH THE 31/00Z ECENS. THE
GEFS WAS A REASONABLE ALTERNATIVE---BUT CONSIDERABLY MORE `ZONAL`
DOWNSTREAM IN THE NORTHEAST PACIFIC AND MAINLAND WEST COAST.

PRIOR TO DAY 6 (6/12Z)---PLEASE CONSULT THE CENTRAL PACIFIC
HURRICANE CENTER (CPHC) FOR THE MOST RECENT WEATHER INFORMATION
CONCERNING `KILO` AND `IGNACIO`.
