HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
716 AM EDT THU MAY 28 2015

VALID 00Z FRI MAY 29 2015 - 00Z FRI JUN 05 2015


THE MODELS INDICATE THAT THE TROUGH IN THE WESTERLIES CURRENTLY
AFFECTING HAWAI`I WILL SHEAR OFF TO THE EAST OVER THE WEEKEND,
LEAVING PATCHY DEEP-LAYER MOISTURE BEHIND. BOTH THE 00Z/28 ECMWF
AND THE 06Z/28 GFS SHOW THE APPROACH OF ANOTHER TROUGH FROM THE
NORTHWEST LATE NEXT WEEK, THOUGH THAT WAVE IS CURRENTLY PROGGED TO
BE FLATTER. FIVE-DAY QPF TOTALS THROUGH 00Z/03 WEDNESDAY ARE
GENERALLY 0.25-0.50", WITH HIGHER AMOUNTS INTO THE FAVORED
TERRAIN. THE ECMWF IS STILL QUITE WET OVER THE NORTHEASTERN BIG
ISLAND, WITH UPWARDS OF 5.00" DURING THAT PERIOD.
