HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
234 AM EDT FRI MAR 28 2025
VALID 00Z SAT 29 MAR 2025 - 00Z SAT 05 APR 2025
AN UPPER RIDGE OVER HAWAII SHOULD LINGER INTO THE WEEKEND
BRINGING WEAKER TRADES AND LIGHTER RAINFALL. BY NEXT WEEK, THE
RIDGE SHOULD SLOWLY SHIFT EASTWARD AS AN AMPLIFIED TROUGH OR UPPER
LOW HOLDS 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 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, AT LEAST THROUGH NEXT
WEEK.
