Synopsis for hawaiian coastal waters.. An area of high pressure far north of the islands will move northeast, further away from the islands through Saturday, resulting in weakening trade winds Saturday. Mainly moderate trades will hold over the weekend with further weakening early next week. A front will be dissipating upon reaching the islands tonight. Elements of this front, and the interaction of an upper level disturbance, may lead to a slight chance of a Thunderstorms over the windward waters of maui and the big island tonight. A large northwest swell is expected to arrive Tuesday of next week.

Area Forecast Discussion National Weather Service Honolulu HI 957 AM HST Fri Nov 27 2020

SYNOPSIS. Moderate to breezy northeast trade winds will prevail through the weekend, with clouds and showers favoring windward and mountain locations. Windward shower coverage could increase tonight into Saturday as an upper disturbance and dissipating front move through from north to south. Trade winds will diminish early next week as a cold front passes north of the state.

DISCUSSION. Surface high pressure is centered far to the north of the area providing for moderate to breezy northeast trade winds across the state. Meanwhile, the axis of an upper level trough is located just to the northeast of the Big Island. The airmass is rather dry and stable at the present time so just a few brief showers are falling over windward and mauka areas. Expect this trend to continue through the day today with daytime heating allowing for some clouds and showers to develop over the Kona slopes this afternoon and evening.

Tonight and Saturday, model guidance indicates that an upper level short wave will be moving around the trough axis causing instability near the Big Island. Some increase in low level moisture is also indicated as an old frontal boundary gets caught up in the northeast trades. Some increase in windward and mauka showers can be expected as this feature moves on through. The instability caused by the short wave aloft, may allow for some heavier showers and a few thunderstorms to form over and around the Big Island. We will take a look at new guidance before deciding on placing thunderstorms into the forecast.

With breezy trades in place and low dewpoint temperatures present, it will likely feel rather chilly during the overnight and early morning hours on Sunday.

By Monday, the surface high will have moved off to the northeast of the area while a frontal boundary begins to approach the area from the northwest. This will cause trade winds to back off with local land and sea breezes developing. The upper trough is forecast to linger just to the northeast of the Big Island so its associated instability may allow for higher chances for afternoon shower development over the leeward Big Island slopes. The front is forecast to dissipate to our north around mid week. Trade winds will remain on the lighter side into the end of the forecast period.

AVIATION. Moderate to locally breezy trades will support prevailing VFR and occasional windward showers through today. A front noted on satellite imagery north of the Islands will bring an increased coverage of showers and potential for MVFR for Windward Kauai tonight and Oahu by very early Saturday morning. AIRMET Tango remains in effect for both lee turbulence due to trades as well as moderate CAT in the FL270-370 layer.

MARINE. While no changes are expected with this mornings coastal waters package, anticipating some changes by the afternoon, mainly with thunderstorm possibilities over the coastal waters. The current forecast has the possibility of thunderstorms over the waters northeast of Maui and the Big Island tonight in response to an upper level shortwave that is expected to swing through, and a dissipating front approaching the islands. However the latest model runs shows the feature strengthen and lingering over the area through Saturday and possibly into Saturday night. The bulk of the instability would be to the northeast of the islands, including some of the offshore waters. Will be refining the area and time of thunderstorms for the waters shortly.

The next significant marine feature will be the large swell expected by next Wednesday, which is expected to produce warning level surf along north and west facing shores. This swell will be generated from a surface low coming off Japan and moving east- northeast over the weekend, passing near the Aleutian Islands early next week. WaveWatch III and the European wave guidance has a 14 foot swell at around 18 seconds reaching the north and west shores of Kauai late Tuesday afternoon. The swell will spread down the island chain, peaking Wednesday followed by gradual decline through Friday. Tides are currently running about half a foot above predicted levels, and high tide Wednesday morning is predicted at 2.3 feet. The high tide and surf arrival will further increase the possibility of runup on roadways during this event. A Small Craft Advisory (SCA) will also be needed as seas exceed 10 feet as early as Tuesday afternoon for waters near Kauai, then quickly spreading to other exposed waters Tuesday night. Seas are expected to fall below SCA levels Thursday afternoon.

High pressure north of the islands will continue to move to the northeast through tomorrow, and we are expecting trade winds to weaken some into early next week. The current SCA is in effect through tonight due to the winds. Once the winds weaken, they are expected to remain below SCA levels through the upcoming week.

A moderate northwest swell is expected to build today and peak on Saturday, with another northwest swell arriving Sunday will maintain moderate through Monday. A small northeast swell will maintain moderate surf along east facing shores through the weekend. Without support of this swell early next week and the lighter trades, surf will be smaller along the east facing shores. Surf will be small along south facing shores through out the period, where a couple of long period pulses from the south- southwest and of south are expected through next week.

HFO WATCHES/WARNINGS/ADVISORIES. Small Craft Advisory until 6 AM HST Saturday for Kauai Northwest Waters-Kauai Leeward Waters-Kauai Channel-Oahu Leeward Waters- Kaiwi Channel-Maalaea Bay-Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters.
