Detailed Forecast

Synopsis

High pressure north and northeast of the islands will keep breezy to windy trades in place through the weekend. Drier trade wind weather is expected through late Wednesday. Upper level troughing, along with an influx of moisture from the east, will likely increase shower coverage and intensity Thursday through the weekend.

Discussion

A high far northeast of the main Hawaiian Islands is driving fresh to strong trade winds across local waters this evening, while a trough sits about 600 miles west of Kauai. Satellite loop shows broken to overcast low clouds across most windward areas as well as across upper slopes of Kona district of the Big Island. Overcast layered clouds along the eastern flank of an upper trough to the west of the island chain are beginning to drift eastward across Kauai. Radar shows light to moderate showers drifting across Kauai and across windward portions of Maui and the Big Island. Showers will taper off tonight before the next cloud band moves in by the trades late Wednesday.
The high northeast of the state will strengthen Wednesday night, boosting wind speeds through Friday night. Troughing northwest of the state will then cause winds to decrease again this weekend. Daytime wind speeds will likely be at or just below advisory levels in exposed areas over the next few days.
A broad upper trough will develop across the islands and persist into this weekend. This will raise the inversion and enhance trade wind showers. An elevated inversion will limit strong downsloping wind gusts. Showers will continue to favor windward and mauka areas. We will consider the possibility of thunderstorms as time gets closer.

Aviation

The primary aviation hazard during the forecast period will be breezy to locally strong trades, including an increased threat for a localized wind shear hazard at susceptible locations. Additional slight strengthening of the trades is expected during the forecast period. In the near term, Windward Maui through Big Island will experience frequent reductions to MVFR as showers expand in coverage and stream onshore. As a result, AIRMET Sierra for mountain obscuration has been issued for those locations. Prevailing VFR is forecast elsewhere.
AIRMET Tango remains in effect for lee turbulence for the entire area.

Marine

Strong high pressure north and northeast of the islands will keep strong to near gale force easterly trade winds blowing through early next week.
A combination of strong trade winds and elevated seas will produce Small Craft Advisory conditions across most coastal waters at least through the weekend, and possibly into the first half of next week. A Gale Watch remains in effect for the Alenuihaha Channel starting on Wednesday morning as trade wind speeds are forecast to strengthen.
Strong trade winds will produce elevated surf along east facing shores through the first half of next week. A High Surf Advisory (HSA) remains in effect for east facing shores of Kauai, Oahu, Molokai, Maui and the Big Island through 6 AM Saturday. This HSA will likely need to be extended into early next week.
A series of small overlapping northwest swells will move through the area through the weekend. Surf heights along exposed north and west facing shores will remain below HSA thresholds through early next week.
A small out of season south swell will give a boost to south shore surf late Thursday through early Saturday. Otherwise, surf along south facing shores will remain small through early next week.
