HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
401 AM EDT TUE JUL 11 2023
VALID 00Z WED JUL 12 2023 - 00Z WED JUL 19 2023
A FAIRLY TYPICAL AND PERSISTENT TRADE WIND PATTERN SHOULD HOLD
OVER HAWAII FOR THE NEXT WEEK WITH SURFACE HIGH PRESSURE HOLDING
STRONG NORTH/NORTHWEST OF HAWAII AND AN UPPER LEVEL RIDGE OVER THE
STATE. A POCKED OF INCREASED MOISTURE SHOULD MOVE THROUGH THE
STATE TODAY (ASSOCIATED WITH FORMER TROPICAL CYCLONE ADRIAN) WITH
SLIGHT INCREASES IN CHANCES FOR WINDWARD AND MOUNTAIN SHOWER
COVERAGE. OTHERWISE, DRIER CONDITIONS AND MODEST TRADES SHOULD
PERSIST INTO NEXT WEEK. TRADE WIND SPEEDS AND MOISTURE MAY BEGIN
TO INCREASE AROUND NEXT TUESDAY AS A TROPICAL DISTURBANCE
APPROACHES THE ISLANDS. THE MODELS CONTINUE TO HAVE A GOOD HANDLE
ON THE OVERALL PATTERN OVER HAWAII, WITH UNCERTAINTIES IN THE
DETAILS, ESPECIALLY SURROUNDING ANY KIND OF POTENTIAL TROPICAL
SYSTEM AROUND THE MIDDLE OF NEXT WEEK TO THE EAST OF HAWAII.
