Hawaii Extended Forecast Discussion
NWS Weather Prediction Center College Park MD
346 AM EDT Mon Oct 02 2023

Valid 00Z Tue Oct 03 2023 - 00Z Tue Oct 10 2023

The pattern across Hawaii is forecast to be changing Monday, as a
surface low well north of the state pushes a front across the
Pacific that is forecast to hover north of the islands, disrupting
the pressure gradient over the state. This will weaken winds and
allow for sea and land breezes to set up, with clouds and showers
favoring that pattern through Tuesday and Wednesday. The front
looks to stall and dissipate just north of Hawaii around Wednesday
night/Thursday, with the band of moisture ahead of it perhaps
making it into the northwestern islands, but any enhanced rain
looks to stay north. By late week a surface high is forecast to
form northwest of the state and extend its ridge toward Hawaii,
with its pressure gradient sufficient to reform easterly trades.
The more typical trade wind pattern should persist through the
weekend into early next week, with any showers focused on
windward/mauka areas.
