Detailed Forecast

Synopsis

Locally breezy trades will focus clouds and showers over windward areas through the week. An increase in showers is expected Wednesday and Thursday.

Discussion

Locally breezy trade winds will remain in place for the next couple of days as a pair of high pressure cells pass far north of the state. A mid level ridge will maintain stable conditions that will focus rainfall over windward areas and allow clouds and a few showers to develop over leeward Big Island slopes each afternoon. Small pockets of moisture within the trade winds will periodically boost windward rainfall, though rather dry conditions will prevail today. Winds on the summit of Haleakala will continue to decline today, and the advisory has been cancelled.
An increase in shower activity and a slight decrease in winds is expected mid week. A dissipating front, currently 800 miles northeast of the islands, will fall apart over the next couple of days, leaving a diffuse pool of low level moisture that will move over the state Wednesday and Thursday. A weak upper level trough will accompany this feature, likely providing a boost in showers, The upper trough will also relax the local surface pressure gradient and cause trades to drop slightly.
Expect moderate to locally breezy trade winds and a typical pattern of mainly windward showers heading into next weekend.

Aviation

Breezy easterly trade winds will continue, with clouds and light showers favoring windward and mauka locations. AIRMET Sierra for mountain obscuration remains in effect for windward areas of Kauai and Oahu through the early morning hours. A return of VFR CIGS is expected by mid morning.
AIRMET Tango remains in effect below 8000 feet over and immediately south through west of all mountains due to tempo moderate turbulence.

Marine

A high pressure ridge remains locked in place north of the islands through the week, producing moderate to locally strong trade winds each day. A Small Craft Advisory (SCA) remains in effect for the typical windier waters near Maui and the Big Island through Tuesday night. This SCA will likely be extended for these windier eastern waters and channels through the weekend.
The current small, medium period west-northwest swell will slowly fade through Wednesday. A larger, long period west-northwest swell will arrive in the islands on Thursday, elevating surf heights along exposed shores through Friday. A third larger, medium period, west-northwest swell arrives from Friday night onward, producing elevated surf along north and west facing shores through next weekend.
Overlapping background south swells will continue to keep small surf heights along south facing shores through Wednesday. A slightly larger, long period southwest swell generated from the Tasman Sea basin will arrive on Thursday, elevating south shore surf through next weekend. Choppy surf along east facing shores will build closer to seasonal averages through the week as trade winds strengthen.

HFO Watches/Warnings/Advisories
