Summary

A streak of clouds and showers marking a dissolving front will bring wet conditions to windward Oahu and Maui Counties this morning when the trade winds return. From Friday to the weekend, increasing trade winds and a typical pattern of wind showers can be expected, followed by decreasing trade winds at the beginning of next week.

discussion

The residual moisture left by a front moving northeast brings cloudy skies and showers over Oahu and Maui Counties, with partly cloudy skies and occasional showers over Kauai and the Big Island. Clouds and showers will linger over the central islands today as the trade winds gradually fill in and push moisture into the windward areas. A high pressure will build up in the north by Friday, which will accelerate the northeast trade winds to a moderate level today and turn into breezy east trade winds at the weekend. Typical trade wind weather is expected, with showers concentrated over windward and mountain areas and reaching a few wind directions. In the long run, the trade winds are likely to sink a notch early next week as a disturbance develops to the west and northwest of the islands. This scenario would turn the winds from the east to the southeast, with the shower potential increasing somewhat by mid-week when an upper trough moves over them.

aviation

Residual moisture from a dissolving stationary front will continue to bring increased shower activity from Oahu to Maui through this afternoon. However, light to moderate trade wind currents should concentrate the showers on locations on the windward side. Expect short periods of MVFR caps and visibility to accompany this activity.
AIRMET SIERRA remains in effect for Tempo Mountain Darkening over 2500 feet for north to east facing areas of Oahu, Molokai and Maui.

marine

Moderate to fresh trade winds have returned from the northeast over the waters of Kauai and Oahu and should fill in over the eastern end of the state until tonight as high pressure builds up in the north. Trade will spike eastward and into the fresh to strong category on Friday through the weekend, likely creating small craft advisory terms for the normally windier waters between Maui County and the Big Island. Winds may ease and shift from east-southeast early next week as the ridge weakens in response to a front moving north.
Surfing along the north and west coasts will increase until the weekend today as a mix of medium-term, north-northwest and long-term, west-northwest swells pervades. The mid-range north-northwest swell filled overnight and should last until Friday before subsiding into the weekend. The long-lasting west-northwest swell will fill in on Friday and peak by early Saturday near or at advisory levels for exposed shores of the smaller islands.
Surfing along the south-facing coastlines will continue until Friday, while a long south-south-west swell runs through it. Morning observations at the offshore buoys to the south and the offshore PacIOOS Barbers and Lanai buoys have reflected this new energy within the 18-22 second bands. This source will slowly fade over the weekend. Looking ahead to next week, the projections are mostly showing sustained southern background energy that should keep the surf from flattening out.
Surfing along the east-facing coastlines will stay small through Friday and then increase slightly through the end of the weekend as fresh trade returns locally and upstream. Due to the weakening of trades, there is likely to be another downward trend next week.
