Area Forecast Discussion
National Weather Service Honolulu HI
959 AM HST Sat Dec 17 2022

.SYNOPSIS...
Scattered showers will develop with sea breezes over island
interiors today with isolated thunderstorms possible over portions
of Maui and the Big Island. Showers and thunderstorms will
increase in coverage tonight through Sunday as southwest winds
strengthen. Strong and potentially damaging kona, or southwest,
winds and strong thunderstorms will move through the area Sunday
night through Monday evening. Breezy westerlies will then focus
showers over leeward slopes through Tuesday. Drier conditions and
lighter southwesterly winds are then expected Wednesday through
late next week.

&&

.DISCUSSION...
Currently at the surface, a weak ridge of high pressure is
centered around 425 miles west-northwest of Kauai, with a strong
cold front located around 850 miles northwest of the Garden Isle.
Meanwhile, a weakening front is positioned around 150 miles east-
northeast of Hilo. Visible satellite imagery shows mostly clear
skies across the state with radar imagery showing rain free
conditions over land and just a few showers out over the nearshore
coastal waters. Main forecast concern continues to revolve around
the potential impacts from strong storm system moving through the
islands during the next couple days.

The strong cold front will make steady progress toward the state
today through Sunday, then move from northwest to southeast down
the island chain late Sunday night through Monday evening. Winds
will remain light today and tonight, with sea and land breezes
dominant. Southwesterly winds may begin to develop late tonight,
but will pick up more noticeably Sunday morning, then become
breezy to locally windy Sunday afternoon. Depending on the degree
of stability Sunday afternoon, a Wind Advisory may be needed for
windward areas due to gusty southwesterly downslope winds. The
winds associated with this storm system are expected to peak
Sunday night and Monday, potentially at warning levels. At a
minimum, a Wind Advisory will likely be required for the entire
state during this time, with the strongest winds expected over
windward areas, where a High Wind Watch may be required with the
afternoon forecast package.

Behind the cold front, breezy to locally windy conditions are
expected to continue through Tuesday morning, before easing off
Tuesday night as a weak front approaches from the northwest. Light
to at times moderate southwesterly winds will then prevail
Wednesday through Friday as a progressive pattern across the
Pacific keeps the surface ridge axis suppressed south of the
state. The ridge axis could lift north of the islands next
weekend, bringing a return of light to moderate trades.

As for the remaining weather details, quite an active next several
days can be expected across the island chain as the strong storm
system approaches and moves through the region.

Rest of today,
Dry conditions should prevail across the state through the
remainder of the morning, with sea breezes assisting in the
development of scattered showers this afternoon, primarily over
interior and windward locales. Mid-level moisture and instability
will remain high enough over Maui and the Big Island that a
thunderstorm or two can't be ruled out this afternoon. Elsewhere
the mid-level will remain very dry and thunderstorms are not
expected.

Tonight and Sunday,
Mid-level moisture will increase statewide this evening, with
forcing for ascent trending upward as the night progresses.
Daytime heating driven showers should end fairly quickly in the
evening, with most showers then confined to the coastal waters.
Deep layer southwesterly flow increasing after midnight should
lead the development of scattered showers and thunderstorms which
will begin to move onshore. Moisture and instability will hold
over the islands through the day Sunday, and with wind fields
increasing the potential for organized thunderstorms, a few
thunderstorms could become strong with the capability of producing
gusty winds and even hail given the cold temperatures aloft. The
potential for brief downpours appears high, however the flow
should remain progressive enough to keep the chances for
widespread flooding low, and a Flood Watch is not anticipated at
this time.

Sunday night through Monday night,
The potential for organized thunderstorms will peak Sunday night
through Monday evening as deep layer 0-6 km shear values
increases to between 40 and 60 knots. This combined with 1500 to
2000 J/KG of surface based CAPE and cold air aloft with -20C
heights lowering to between 18 and 20 kft, points to the potential
for strong thunderstorms capable of producing damaging winds and
large hail. The greatest potential for Severe weather will exist
along and immediately ahead of the cold front. Some locally
heavy rainfall can't be ruled out either, and given the potential
for training of deep convection, a Flood Watch may eventually be
needed for the Sunday night through Monday evening time frame.
Lingering deep moisture and instability could keep some strong
thunderstorms over the Big Island Monday evening, with conditions
quickly stabilizing after midnight as the front exits to the east.

Tuesday through next Saturday,
Both the GFS and ECMWF are in good agreement showing lingering
deep moisture over the state keeping conditions showery on
Tuesday. Drier weather should then settle into the region Tuesday
night through next weekend, with limited showers favoring the
typically dry leeward areas due to the southwesterly boundary
layer flow.

&&

.AVIATION...
For this morning, expect rather dry weather to persist with VFR
conditions and light winds. By this afternoon, weak instability
aloft and sea breezes development along the coasts will allow for
shower development over the interior of the islands. By tonight,
especially late tonight, shower activity with isolated
thunderstorms will increase from the southwest and spread over
state. Periods of MVFR ceilings and visibility may accompany any
of the heavier showers or storms.

There are no AIRMETs in effect.

&&

.MARINE...
A ridge of high pressure near the state will produce light and
variable winds through tonight. The large northwest swell that
filled in yesterday is still producing seas above 10 feet and a
Small Craft Advisory remains in effect for these exposed waters.
Seas are expected to drop below 10 feet by this evening as the
northwest swell declines.

A seasonably active weather pattern is expected starting tonight as
a potent cold front begins to approach the state. Showers and
isolated thunderstorms will begin to increase over area waters and
winds will begin to increase during the day Sunday. As the front
sweeps through the island chain Sunday night and Monday, winds
will increase to near-gale to gale force southwest to west winds.
Additionally, isolated severe thunderstorms capable of producing
damaging winds will be possible during this time. Winds are
expected to remain strong and out of the west on Tuesday then
rapidly decline Tuesday night into Wednesday as a ridge of high
pressure builds over the state.

The powerful low sending the cold front over the islands will
produce a series of extra large northwest swells that will bring
surf heights well above High Surf Warning levels for most north
and west facing shores Sunday night through Tuesday. Latest wave
run up guidance from PACIOOS shows run up heights above the
critical threshold of 8 feet. This would suggest overtopping of
lower roadways closer to the shore is likely on Monday night into
Tuesday morning during the early morning high tide. This swell is
expected to drop below warning thresholds Tuesday night into
Wednesday. A large west-northwest swell is possible during the
second half of next week.
