HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
800 AM EDT SUN AUG 02 2015

VALID 00Z MON AUG 03 2015 - 00Z MON AUG 10 2015

GUIDANCE REMAINS AGREEABLE REGARDING THE FORECAST EARLY IN THE
PERIOD.  EXPECT MODERATE TO BRISK TRADES AS SUPPORTED BY HIGH
PRESSURE TO THE NORTHEAST OF THE STATE.  AT THE SAME TIME REMNANT
MOISTURE FROM TROPICAL DEPRESSION EIGHT-E SHOULD ENHANCE RAINFALL
SOMEWHAT PRIMARILY OVER THE BIG ISLAND.  THEN THE TRACK OF
GRADUALLY WEAKENING HURRICANE GUILLERMO WILL DETERMINE THE WEATHER
IMPACTS FOR THE AREA IN THE TUE NIGHT TO THU TIME FRAME.  THE 0900
UTC ADVISORY FROM THE CENTRAL PACIFIC HURRICANE CENTER (CPHC)
INDICATES A TRACK JUST A FRACTION NORTH OF THE ISLANDS.  GUIDANCE
SPREAD HAS NARROWED SOMEWHAT FROM YESTERDAY BUT CURRENT
DIFFERENCES REMAIN SIGNIFICANT IN TERMS OF RESULTING RAINFALL AND
WIND SPEEDS/DIRECTION.  CONSULT CPHC PRODUCTS FOR THE LATEST
INFORMATION REGARDING GUILLERMO.  WITH THE PASSAGE OF GUILLERMO,
MODERATE TO BRISK TRADES SHOULD RESUME FROM FRI INTO THE WEEKEND
AS HIGH PRESSURE COVERING THE EASTERN HALF OF THE PACIFIC MAY
DRIFT AS CLOSE TO THE ISLANDS AS 35N LATITUDE.  PRIOR TO THIS TIME
THE SURFACE HIGH IS LIKELY TO BE CENTERED AT LEAST AS FAR
NORTHWARD AS 40N.
