Area Forecast Discussion
National Weather Service Honolulu HI
857 PM HST Wed Feb 5 2025

.SYNOPSIS...
A disturbance moving through the area will bring an increase in
showers across the state through Thursday. The focus of these
showers will likely be over interior and leeward areas during the
afternoon and windward areas at night. Light winds will persist
through Thursday, with moderate trade winds returning by Friday
afternoon. A drier air mass will move in Friday afternoon, with
fair weather conditions expected through early next week.

&&

.DISCUSSION...
Satellite and radar imagery this evening shows a band of showers
along a boundary near east Maui, with scattered showers elsewhere.
These showers will likely linger as a short-wave trough moves
across the state overnight. Guidance continues to show this short-
wave trough enhancing showers over windward areas. With the added
upper level support we could see some brief downpours tonight.
Showers should eventually weaken in intensity and move offshore
later tonight as the land breezes develop. For Thursday, we could
see some showers lingering along the windward coastline in the
morning, but sea breezes will likely develop again by mid day
which should lead to another round of afternoon clouds and showers
over interior and leeward areas.

Starting Friday, a weak upper level ridge will build overhead and
a surface high will build northeast of the state. A ridge
extending from the parent high will fluctuate just north of the
state into early next week. With the ridge staying just north of
the state, we should see stable conditions with generally a trade
wind pattern. For the western half of the state, the winds will be
lighter with winds out of the east to east-southeast direction.
Due to the lighter winds, we could see sea breezes develop over
the interior and leeward areas. Over the eastern half of the
state, we should see our typical trade wind pattern. Overall,
stable with mostly dry conditions are expected this weekend into
early next week.

&&

.AVIATION...
Light east to northeast trades will prevail tonight, allowing
land breezes to be common across most of the state. Slightly
stronger trades are expected Thursday, although they should be
light enough for some localized sea breezes to develop in the
more sheltered areas. An area of enhanced moisture will keep some
showers and MVFR cigs/vsbys around windward areas tonight and
Thursday morning, particularly from Oahu eastward.

AIRMET Sierra remains in effect for mountain obscuration for
windward sections of Kauai, Oahu, Molokai, Maui and Big Island.
Conditions could improve on Kauai and Oahu later this evening, but
will likely remain in place over Molokai, Maui, and Big Island
through much of the night.

&&

.MARINE...
A weak surface ridge stretched over waters just north of Kauai
will support light and variable winds as it remains nearly
stationary through Thursday. The ridge will move north and
strengthen from Friday into the weekend, supporting moderate to
locally fresh trade winds that will favor an E-ESE direction.

The ongoing NE swell will receive another pulse of medium-period
(12-14 seconds) reinforcement from 040 degrees tonight and
Thursday, then gradually diminish Friday/Saturday. The High Surf
Advisory (HSA) for E facing shores has been extended through
Thursday. Peak surf heights along N facing shores will likely
approach but remain below the 15 foot HSA criteria with this
pulse.

A new long-period NW swell is expected to arrive late Thursday
and peak Friday, with peak surf heights likely exceeding HSA-level
heights along N and W facing shores. A similarly-sized (or
slightly smaller) NW swell is expected from Saturday night into
Monday, with a potentially larger WNW swell from late Tuesday into
Thursday next week.

Winds and seas are expected to remain below Small Craft Advisory
(SCA) criteria for the time being. In those zones exposed to the
NW swell, seas are expected to rise back above Small Craft
Advisory (SCA) criteria Thursday night and Friday, and then again
over the weekend. An SCA for winds may also be needed around Maui
and the Big Island this weekend if E winds rise above SCA speeds
due to the strengthening ridge.
