Detailed Forecast

Synopsis

Gentle to moderate east to southeast trade winds will strengthen this afternoon and veer toward the east. Moisture moving in from the southeast will bring scattered showers across the state today with a drier trade wind pattern returning on Thursday. Trades will likely weaken on Sunday as a cold front approaches the state. This front could bring gusty northerly winds and showery weather during the first half of next week.

Discussion

Gentle to moderate east to east southeast breezes will gradually strengthen and veer back easterly this afternoon into Thursday as the front north of the state weakens and broad high pressure takes over the east Pacific.
Overnight, we did see some moderate rain showers impacting windward areas of the Big Island, Maui and Oahu. For today, we should see the moisture continue to spread toward the western end of the island chain with showers on the increase over Kauai and Oahu. Afternoon sea breezes will develop over select areas and will lead to afternoon showers over interior and leeward areas. Showers are expected to continue over windward Big Island and Maui today with a decrease in showers expected tonight into Thursday as a drier airmass moves in from the east. A drier than normal trade wind pattern is expected Thursday through Saturday, with some light passing showers over windward and mountain areas.
In the extended forecast, an approaching front will disrupt the trade winds Sunday into Monday. Although confidence remains low being this far out in time, we could see the front pass through the state with gusty northerly winds behind the front and showery conditions around Tuesday of next week. More details will follow as the week progresses and confidence increases.

Aviation

Strengthening easterly trade winds will expand westward across the islands through this afternoon, as a ridge of high pressure lingers northeast of the state. Weaker wind patterns across sheltered zones will continue the potential for diurnal circulations through tonight, with sea breeze development expected this afternoon generating clouds and isolated showers inland across most leeward zones. VFR conditions are expected at most locations throughout the forecast period, however periods of MVFR cigs continue within showers across mainly eastern portions of the state and Big Island.
AIRMET Sierra remains in effect for tempo mountain obscuration for eastern portions of state, especially sections of Big Island. Tempo mountain obscuration conditions may expand westward this afternoon in increasing moist trade wind flow.

Marine

Light to moderate east to southeast winds will transition to moderate to locally breezy trade winds today as a ridge of high pressure moves farther north of the state. With this change, a Small Craft Advisory will take effect by midday for the typically windy coastal zones around Maui County and the Big Island. Winds may weaken over the weekend and again veer southeast as a front approaches from the northwest.
The current northwest swell will only marginally decline and veer toward the north-northwest over the next day or two. A series of smaller northwest swells are expected Thursday through Saturday, with surf peaking below advisory levels. A larger northwest swell is possible early next week, with forerunners as early as Monday, that could raise surf to advisory levels along north and west facing shores through mid-week.
Surf along south facing shores is forecast to remain small, with only small background swells through the week. A small south swell is possible towards the middle of next week. East facing shores will have small, choppy surf through the week due to the local trades.

HFO Watches/Warnings/Advisories

Small Craft Advisory from noon today to 6 AM HST Friday for Maalaea Bay, Pailolo Channel, Alenuihaha Channel, Big Island Leeward Waters, Big Island Southeast Waters.
