HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
359 AM EDT SUN AUG 27 2023
VALID 00Z MON AUG 28 2023 - 00Z MON SEP 04 2023
A WEAK UPPER-LEVEL TROUGH IS FORECAST TO INFLUENCE HAWAII THROUGH
AROUND MONDAY, ALLOWING FOR A LITTLE MORE VERTICAL MOTION TO FORM
SHOWERS, THOUGH MOISTURE LEVELS LOOK TO BE NEAR TO BELOW NORMAL. A
SLIGHTLY WEAKER PRESSURE GRADIENT AT THE SURFACE SHOULD CAUSE
TRADES TO STAY AROUND MODERATE LEVELS, WHICH COULD LEAD TO A
HYBRID PATTERN OF SEA/LAND BREEZE SHOWERS FORMING AS WELL AS
SHOWERS FAVORING WINDWARD/MAUKA AREAS.
BY TUESDAY AND THROUGH MUCH OF THIS WEEK, UPPER AND SURFACE HIGHS
SETTING UP NORTHEAST OF THE STATE WILL LEAD TO STRENGTHENING
TRADES AND DRIER CONDITIONS. MEANWHILE SOMETHING TO MONITOR BY
LATE IN THE WEEK IS THE POTENTIAL FOR WHAT IS CURRENTLY TROPICAL
DEPRESSION TEN-E TO TRACK WESTWARD TOWARD THE STATE. THE LATEST
FORECASTS CONTINUE TO SHOW THE SYSTEM WEAKENING INTO A
POST-TROPICAL LOW OR JUST A TROUGH BY THE TIME IT WOULD NEAR
HAWAII. BUT THE SURFACE FEATURE OR AT LEAST THE MOISTURE FROM THE
FORMER SYSTEM MAY AFFECT THE STATE BY NEXT WEEK.
