.SYNOPSIS...
A cold front will approach the islands from the northwest today,
southerly winds will steadily build along with an increase in
showers, mainly over the western end of the island chain. The
front is expected to reach Kauai tonight then stall near Oahu on
Wednesday, bringing the potential for periods of wet and unstable
conditions into the weekend.

&&

.DISCUSSION...
Infrared satellite shows an approaching cold front currently
about 200 miles northwest of Kauai. The front is characterized as
a layered cloud band north of 23N with shallower moisture south of
this latitude. A line of thunderstorms is observed along the
forward side of the front currently about 150 miles northwest of
Kauai. The front is supported by a low in the North Central
Pacific northwest of the state. The polar jet, which runs along
the southern flank of the low, will be forced south near Hawaii
over the next several days.

Winds will shift out of the south ahead of the front today becoming
locally breezy across Kauai and Oahu through Wednesday. Light wind
flow across Maui County and the Big Island will allow sea breezes
to set up this afternoon. Vog from the Kilauea Volcano will also
track up over the smaller islands. Also on the Big Island, a Wind
Advisory is posted for the summits today with a High Wind Watch
going into effect tonight through Wednesday afternoon. The strong
wind aloft are the result of the approaching weather system.

The cold front will reach Kauai by tonight, with increasing clouds,
showers and thunderstorms reaching Kauai by this afternoon and
Oahu this evening. Increasing shear values along the thunderstorm
band tonight could allow some storms become organized producing
gusty winds at times. Models show the front stalling out and
weakening near Oahu on Wednesday and Wednesday night with the
associated showers and thunderstorms advancing as far east as
Molokai on Wednesday.

For Super Blue Blood Moon eclipse watchers tonight and early
Wednesday morning, extensive cloud cover remains in the forecast
for Kauai and Oahu where eclipse viewing will remain challenging.
Cloud cover will improve from Molokai eastward with the best
locations for viewing this event are expected over Maui and the
Big Island.

Overall shower coverage may briefly fade late in the day Wednesday
as the southerly winds weaken. However, the southerly winds and
showers will increase again by early Thursday morning as the next
approaching cold front begins to influence our weather. This
approaching front marks the first over several front and pre-
frontal convergence bands that will pass over the state from
Thursday through this weekend, resulting a prolonged period of
unsettled wet weather.

.AVIATION...
Building southwest winds and VFR conditions will prevail over
most areas today, and isolated MVFR conditions will be confined
to southwest facing slopes through most of the day as a front
approaches. MVFR ceilings and SHRA will increase this afternoon
across the western end of the state, and the front is expected to
impact Kauai before sundown. The front will bring widespread MVFR
conditions and likely produce mountain obscuration to Kauai as
early as late this afternoon. There is also the potential for a
line of organized thunderstorms along the leading edge of the
front as it reaches the Garden Isle. The front will reach Oahu
late tonight and stall over the islands on Wednesday.

No AIRMETs are currently in effect. AIRMET Tango will likely be
needed for moderate low level turbulence in non-typical areas,
over and to the north thru east of the mountains at some point
later today. AIRMET Sierra may also be needed for mountain
obscuration for Kauai later today and possibly over Oahu tonight.

&&

.MARINE...
A Small Craft Advisory (SCA) is in effect for waters near Kauai
due to southerly winds increasing ahead of a front approaching
from the northwest. Some combined seas will reach near 10 ft with
the approaching front this afternoon and tonight. The SCA level
winds are not expected to spread farther down the island chain.

A series of northwest and north swells will impact the islands
through the end of the week. These swells are expected to bring
combined seas in excess of 10 ft to the waters exposed to the
swells, so anticipate additional areas to be added to the SCA
later in the week.

A north swell is peaking this morning somewhat larger than
expected, so a High Surf Advisory has been issued for north facing
shores of all islands through this afternoon. This swell and the
resulting surf will quickly decline tonight through Wednesday.
However, a larger northwest swell is due to arrive Wednesday
night and Thursday. This swell will likely bring advisory level
surf to north and west facing shores during its peak, and could
approach low end warning levels. A larger northwest swell is
expected to arrive Friday, peak Saturday, then lower a bit on
Sunday and Monday. Surf heights with this swell are expected to
reach warning levels from late Friday through Saturday.

A small east swell produced from trade winds upwind of the state
will continue to produce some elevated surf along east facing
shores through Thursday, but will remain below advisory levels.

See the latest Oahu Surf Discussion (SRDHFO) for additional
details on surf and swell.
