NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
737 AM EDT FRI MAY 29 2015

VALID 00Z SAT MAY 30 2015 - 00Z SAT JUN 06 2015


THE MODELS INDICATE THAT THE TROUGH IN THE WESTERLIES CURRENTLY
AFFECTING HAWAI`I WILL SHEAR OFF TO THE EAST OVER THE WEEKEND,
DRAGGING A LONG TAIL OF DEEP-LAYER MOISTURE BEHIND. BOTH THE
00Z/29 ECMWF AND THE 06Z/29 GFS SHOW THE APPROACH OF ANOTHER
TROUGH FROM THE NORTHWEST LATE NEXT WEEK. THAT WAVE IS PROGGED TO
BE FLATTER, AND WILL HAVE A SUPPRESSIVE EFFECT ON THE MOISTURE
ACROSS THE STATE. FIVE-DAY QPF TOTALS THROUGH 00Z/03 THURSDAY ARE
GENERALLY 0.50-1.00", WITH SLIGHTLY HIGHER AMOUNTS INTO THE
MOUNTAINS.
