HAWAII EXTENDED FORECAST DISCUSSION

300 AM EDT SAT MAR 29 2025
VALID 00Z SUN 30 MAR 2025 - 00Z SUN 06 APR 2025
AN UPPER RIDGE OVER HAWAII SHOULD LINGER THROUGH MUCH OF THE
WEEKEND BRINGING WEAKER TRADES AND LIGHTER RAINFALL. BY NEXT WEEK,
THE RIDGE SHOULD SLOWLY SHIFT EASTWARD AS AN AMPLIFIED TROUGH OR
UPPER LOW MEANDERS NORTH OF THE STATE WITHIN AN OVERALL BLOCKY
PATTERN. THERE IS A LOT OF SPREAD IN THE GUIDANCE STILL FOR
WHATEVER DEVELOPS NORTH OF THE STATE, WITH THE BETTER CONSENSUS
SUGGESTING A DEEP AND FAIRLY STATIONARY UPPER LOW. THE LATEST GFS
RUNS HOWEVER CONTINUE TO HAVE A MORE STRUNG OUT UPPER TROUGH AND
IS NOT THE FAVORED SOLUTION AT THIS POINT. THE COLD FRONT FOR THIS
SYSTEM MAY EVENTUALLY REACH CLOSE TO THE NORTHERN ISLANDS
ALLOWING FOR STRENGTHENING SOUTHERLY WINDS. PRECIPITATION CHANCES
SHOULD INCREASE AS WELL, BUT GUIDANCE SHOWS THE HEAVIEST
PRECIPITATION SHOULD REMAIN WEST OF THE ISLAND CHAIN.
