Synopsis
Stable conditions will prevail through Thursday as a ridge persists
in the island vicinity. Showers carried by the south to east wind
flow will affect the windward areas at times, while afternoon clouds
and a few showers will develop over the islands under daytime sea
breezes, and partial clearing at night under land breezes. A front
is expected to bring an increase in showers Friday into Saturday,
with cooler condition spreading across the islands.

Discussion
Fair weather prevails across the state this evening, and will
continue through Thursday as a ridge of high pressure persists in
the island vicinity, bringing stable and light southerly winds. A
land and sea breeze regime will reign under the light southerly
winds, with a few clouds and showers developing over the islands
each afternoon, followed by mostly clear conditions overnight and in
the morning hours. The light southeast background winds will carry
some clouds and showers from the east, reaching the windward areas
of the islands at times. Rainfall amounts will be low.

The next front is still expected to reach the islands Friday into
Saturday. Latest forecast solutions still indicated this front
passing down the island chain will be weak, as the main upper level
support with this system stays northeast and east of the area. There
will be enough moisture associated with the front to bring a period
of showers, especially along windward areas and north facing slopes.

Behind the front, northeasterly winds should usher in a cool air
mass with dew points dropping into the upper 50s.

Aviation
A deep-layer ridge over the islands will promote a mostly dry and
stable atmosphere, with limited cloud and shower coverage. A surface
ridge over the islands will drift N through Tuesday as a stalled
front just N of kauai dissipates. Light winds will prevail over
kauai and oahu, while light to moderate ese winds are expected over
maui county and the big island.VFR conditions will continue to
prevail statewide, and no airmets are anticipated.

Marine
A stalled front just northwest of kauai is slated to move north
shortly and dissipate over the far northern offshore waters on
Tuesday. This opens up the opportunity for a ridge over the smaller
islands to move north slowly through Tuesday, resulting in winds
backing to the east and southeast across the main hawaiian islands
by Tuesday night. Another front is expected to enter the far
northwest offshore waters Thursday evening. The front is expected to
fall apart as it reaches kauai late Friday afternoon. Strong and
gusty northeast winds follows immediately behind the front Friday
night through Saturday morning before easing off moderate to locally
strong. A gale low is forecast to form along this front 750 nm
north- northeast of the islands over the weekend, with the trailing
nearly stationary front draped across the far and southern offshore
waters. At the same time, another front is expected to stall and
fall apart just west of our far western offshore waters. This setup
will keep the islands under a moderate to strong north to northeast
wind flow.

What appears to be the new northwest swell peaked at buoy 51101
earlier today. The start of an extended period of a reinforcing
west- northwest swell of 300 to 310 degrees, is expected to reach
this buoy later tonight. This swell will continue to build through
Tuesday. As for our islands, this swell will reach kauai early
Tuesday evening, and peak Wednesday at 10 to 11 feet and 16 seconds.

A reinforcing west-northwest pulse arrives Thursday night, peak
early Friday, followed by a gradually drop through the upcoming
weekend. This translate to an extended period of advisory-level
surf to near warning levels, for north and west facing shores, late
Tuesday night through Wednesday, then again Thursday night through
Friday.

From this direction, the swell will reach the kona coast, from kona
to south point Tuesday night, the swell and surf will peak
Wednesday, followed by the second pulse Friday and Friday night,
thus maintaining advisory level surf in the process.

The occurrence of the gale low north-northeast of the islands over
the coming weekend, will lead to slight bump along the exposed north
and east facing shores early next week. Before this happens, a
slight rise is expected along the east facing shores Wednesday into
the second half of the week due to a pocket of fresh to strong winds
upstream of the state. Surf along south facing shores will remain
near the seasonal average through the week with mainly background
short- period southeast trade wind swell energy.

Hfo watches warnings advisories
None.
