Detailed Forecast

Synopsis

Moderate easterly trade winds will continue through Thursday with clouds and light showers favoring windward and mountain locations. Trade wind speeds will decrease slightly from Friday through Sunday, allowing land and sea breezes to develop over western and leeward sections of each island. A stable and dry atmosphere will limit shower coverage and amounts lasting into early next week.

Discussion

A high pressure ridge north of the islands will keep stable moderate trade wind weather in the forecast through Thursday. Model cross sections continue to show trade wind subsidence inversion heights in the 5,000 to 7,000 foot range, limiting vertical cloud development and shower coverage. Brief passing showers may develop in the overnight to early morning hours over windward and mountain areas in this pattern. Most leeward areas will remain dry.
The ridge north of the islands will weaken slightly from Friday into the weekend. Local scale land and sea breezes will develop over western and leeward slopes of each island this weekend as large scale trade wind speeds decrease in strength. Clouds will build over island mountain and interior sections each day from late morning to afternoon with isolated showers possible. A fairly stable temperature inversion aloft will tend to limit shower coverage and amounts in this hybrid trade wind and sea breeze weather regime.

Aviation

Moderate easterly trade winds will continue through tomorrow as high pressure remains in place north of the island chain. Stable air overhead will allow VFR flight conditions to prevail at most locations, though latest satellite imagery and surface observations early this morning show isolated areas of low clouds along windward sections of the islands. Although there are currently no AIRMETs in effect, tempo mountain obscuration could become an issue for windward Kauai and Oahu later this morning. Otherwise, MVFR ceilings and visibility will continue to be isolated in nature throughout the forecast period and favor north through east facing sections of the islands. Additionally, leeward clouds are forecast to increase once again this afternoon across western sections of the Big Island before clearing late tonight.
Looking ahead, trade winds will gradually weaken by Friday, which could allow for land and sea breezes to set up across the island chain.

Marine

High pressure far northeast of the state will maintain moderate to fresh trade winds across the coastal waters through Thursday. The Small Craft Advisory for typically windy waters around Maui County and the Big Island has been cancelled as winds have eased below criteria level. Trade winds are expected to ease Friday into the weekend as the ridge weakens slightly moves closer to the state.
The current south swell appears to have peaked at NDBC offshore buoy 51002, however energy levels still remain elevated. The wrap from this long period south swell is providing a boost in surf heights along exposed west facing shores. A High Surf Warning remains in effect until noon today for all south facing shores. Surf heights are expected to slowly subside to High Surf Advisory criteria later today through early tomorrow morning, then continue to subside into the weekend. A smaller, long period south swell is expected to fill in over the weekend, keeping surf near seasonal averages.
Small surf along north facing shores will continue to dwindle as the last remaining fragments of the current northwest swell moves out. A small, medium period north swell may begin to fill in late tomorrow night, providing a small boost in surf heights Friday into the weekend. Another small, slightly longer period northwest swell may overlap over the weekend providing an additional small boost to north and west facing shores. Surf along east facing shores will remain smaller than average due to the lack of strong trade winds. The one exception will be for areas exposed to the south swell.

HFO Watches/Warnings/Advisories

High Surf Warning until noon HST today for south facing shores of all Hawaiian Islands.
High Surf Advisory from noon today to 6 AM HST Thursday for south facing shores of all Hawaiian Islands.
