Area Forecast Discussion National Weather Service Honolulu HI 842 PM HST Sat Apr 27 2024

SYNOPSIS
Moderate trades will prevail over the eastern islands through the first half of next week, while light to moderate trades over the western islands allow for some leeward land and sea breezes. A plume of moisture will keep showery weather over windward areas tonight and early Sunday. Drier conditions will then develop by Sunday afternoon and persist through Tuesday, with a few showers possible over interior and leeward areas each afternoon, while showers will remain limited to mainly windward areas at night. The trades will rebound Tuesday night and Wednesday, bringing a return of more typical trade wind weather. The trades will become breezy Thursday through next weekend, and the trade wind showers may increase as well due to a disturbance aloft moving over the islands.

DISCUSSION
Currently at the surface, a front is located around 550 miles west-northwest of Kauai, while a 1030 mb high is centered around 1300 miles northeast of Honolulu. Moderate to locally breezy trade winds prevail over the eastern end of the state, while light to moderate trades remain over the western islands. Infrared satellite imagery shows mostly cloudy conditions in most areas, with a bit less cloud cover over leeward sections of Maui County.
Radar imagery shows numerous showers moving into windward slopes and coasts, with a few showers also in leeward areas of Kauai and Oahu. Main short term focus revolves around trade wind trends and rain chances during the next few days.

A front northwest of the state will gradually weaken into a trough during the next few days as it edges slowly eastward. A slight easing of the trades can be expected as we head into the first couple days of the work week. Overall, moderate trades look to hold on over the eastern islands, while lighter trades prevail over the western islands, allowing some leeward sea and land breezes to develop. We should see the trades start to rebound beginning Tuesday night as the trough west of the state begins to shift westward. Moderate to locally breezy trades should overspread the state by late Wednesday, with the trades becoming breezy across the entire island chain Thursday through next weekend.

As for the remaining weather details, a band of moisture will move through the islands overnight as a shortwave trough lifts northeast across the state. This should keep windward slopes and coasts showery, with a few showers affecting leeward areas as well. A drier airmass is evident in satellite imagery east of the Big Island, this in combination with mid-level ridging building over the islands should bring a notable decrease in shower coverage and intensity for most of the state by Sunday afternoon.
Shower activity should be rather limited in most windward areas Sunday afternoon, although some leeward shower development will be possible once again due to localized sea breezes. A more showery Sunday afternoon can be expected on Kauai as the band of moisture will be slower to exit here.

From Sunday night through Tuesday, relatively dry conditions should prevail across the island chain. Brief passing showers will be possible in windward areas each night, with a few showers developing over interior and leeward areas each afternoon. We should see a return to more typical trade wind weather Tuesday night and Wednesday, with wetter trade wind weather potentially developing Friday through next weekend as upper troughing sets up over the state.

AVIATION
A moist ESE flow will continue to provide a steady supply of showers to windward and mauka areas of the Hawaiian Islands overnight into Sunday morning, with tempo VFR conditions expected within heavier showers. With a SE element to the winds, showers will occasionally be steered across leeward areas.

Drier air will move in from the east on Sunday allowing conditions to improve. With the lighter flow and less cloud cover, sea breeze activity will be possible mainly during the afternoon hours.

AIRMET Sierra for mountain obscuration is in effect for portions of the Big Island and Molokai through Kauai. This AIRMET will likely be needed through Sunday morning.

MARINE
Surface high pressure, located roughly 1100 nm northeast of the state, will drive breezy east southeast winds tonight, while an approaching front lies far to the northwest. Through early next week, this surface high will drift eastward and allow flow to weaken. However, by mid-week, easterly flow will once again become breezy.

A Small Craft Advisory for winds will remain in effect for most waters and channels surrounding Big Island, Maui, and Molokai through Sunday, but will likely be dropped by Monday as winds weaken.

Surf heights will remain below advisory thresholds for all shores through the forecast period. A small northwest, medium-period swell will persist through mid- week with small surf expected.
Breezy east or east southeasterly flow will produce choppy surf along east facing shores through Sunday, but will decrease as winds taper off by early next week. Small, short- period southeast, and small medium- period south swell will continue into mid-next week. Surf heights along the south shore should remain near or slightly below seasonal norms.

HFO WATCHES/WARNINGS/ADVISORIES
Small Craft Advisory until 6 PM HST Sunday for Maui County Windward Waters-Pailolo Channel-Alenuihaha Channel-Big Island Windward Waters-Big Island Leeward Waters.
