THE DEPARTURE OF A TROF IN THE ERN PACIFIC WILL ALLOW TRADES TO
RETURN TO NORMAL BY WED. THE NEXT MIDLATITUDE TROF WILL SLIGHTLY
WEAKEN THE TRADES AGAIN THU/FRI. CONSENSUS OF MODELS AND ENSEMBLES
SHOWS THAT A HIGH WILL FINALLY BUILD WELL NE OF THE
ISLANDS...STRENGTHENING TRADES AGAIN NEXT WEEKEND AS AN UPSTREAM
TROF CROSSES THE DATELINE ABOVE LATITUDE 30N. THE GFS PW PROG
SHOWS THAT THE ISLANDS WILL BE IN A RELATIVELY DRY REGIME OVER THE
NEXT WEEK. WHATEVER SHOWERS OCCUR SHOULD BE LIGHTER THAN
AVERAGE...FAVORING WINDWARD LOCALES EXCEPT FOR SOME LEEWARD
SEABREEZE ACTIVITY DURING TIMES OF WEAKER TRADES.
