Hawaii Extended Forecast Discussion

NWS Weather Prediction Center College Park MD

340 AM EDT Sun Apr 28 2024



Valid 00Z Mon Apr 29 2024 - 00Z Mon May 06 2024



Generally east-southeast to east winds are present across Hawaii,

with the slight veering of the winds due to upper and surface lows

to the northwest of the state. These winds should stay light to

moderate over the eastern islands through the first part of the

week, but weak enough over the northwestern islands to allow for a

hybrid trade and land/sea breeze pattern. Meanwhile, available

moisture is forecast to lessen over the next couple of days for

less shower coverage. What is left of the weakening trough may

move across Hawaii around Tuesday.



For midweek and beyond, surface highs developing north of the

state will lead to gradually increasing easterly trades, reaching

moderate to breezy levels by Friday or the weekend. Meanwhile by

late next week into the weekend, model guidance is coming into

better agreement in showing a mid-upper trough/low over Hawaii.

This could provide some instability for increased showers, which

would favor windward areas given the increasing trades.
