Area Forecast Discussion National Weather Service Honolulu HI 957 AM HST Tue Dec 10 2019

SYNOPSIS. Mostly dry weather and light winds will continue through Wednesday as a stable airmass lies over the area. A front will be near Kauai on Thursday with increasing shower coverage expected especially over the west end of the state. Showers will be most numerous over windward and mauka areas as trade winds strengthen due to high pressure building in to our north. A bit drier weather is expected over the weekend and the front weakens into a trough and begins to move away from the area.

DISCUSSION.

High pressure lies far to the east-northeast of the area while a ridge extends west-southwest from the high to a position just north of Kauai. This places the islands in light easterly flow. Winds are light enough allowing for local land and sea breeze development. The northern periphery of an area of enhanced moisture sliding by just south of the state has been providing for some passing showers over southeast sections of the Big Island while most of the remainder of the state is dry as a mid level ridge is in place across the area. Expect generally dry weather for most areas through the day with things expected to dry out eventually over the southeast Big Island slopes.

On Wednesday, a broad upper level trough along with its associated frontal system will be approaching the area from the northwest. Winds will remain light continuing to favor daytime sea breezes and nighttime land breezes. A few showers may develop during the afternoon hours mainly over interior areas.

By Thursday, the front will be located just northwest of Kauai with the upper trough digging down just west of the state. Winds will remain on the lighter side favoring an easterly direction. However they will be light enough for some continuation of local land and sea breeze circulations. Shower coverage is expected to increase over and around Kauai with some increase possible over interior areas of the other islands.

The front is forecast to reach Kauai on Friday with shower activity increasing especially over the west end of the state. Meanwhile, strong high pressure will be building in northwest of the state. This will result in strengthening trade winds especially over the west end of the island chain. This wind direction along with the front's moisture field, will cause windward and mauka areas to receive the majority of the showers but some will likely spill over to leeward areas as well.

The high will be passing by north of the area Friday night and Saturday with moderate to locally breezy trade winds expected across the entire area. Meanwhile the front will have weakened into a trough with its moisture field beginning to shift westward. Shower coverage will likely taper off but there will still be passing windward and mauka showers at times with some leeward spillover still a possibility on into Sunday.

Sunday night and Monday, a new high will be building in north- northwest of the area. Moisture will the old front may get caught up in increasing northeast flow with increasing shower activity possible especially over windward and mauka areas.

AVIATION. With a weak background flow, daytime sea breezes and nighttime land breezes will develop over the state through Wednesday. VFR will predominate over most areas most of the time.

This morning, the one area where MVFR exists is over southeast portions of the Big Island as a weak trough passes south of the area, bringing lower ceilings and showers. Thus, AIRMET Sierra for mountain obscuration is in effect for the Big Island from Hilo to South Cape.

MARINE. Trade winds will remain at gentle to locally moderate strength through tomorrow as a surface ridge holds about 200 nm north of Kauai and a weak front falls apart about 100 miles north of the Garden Isle. Another front will approach then stall just northwest of Kauai on Thursday as strong high pressure builds to the distant northwest. Trade winds will increase locally late Thursday, and as the front is pushed down to near Kauai on Friday, winds will build further. The front will weaken and move off to the west by Saturday, and local winds will decline to moderate to fresh strength as the high moves off to the northeast. Expect stronger trade winds starting Sunday.

Northwest swell will hold around similar heights through tonight then rise. NOAA NDBC buoys northwest of Kauai have been registering the swell at 8 to 10 ft at 13 to 14 seconds since last night, while local PacIOOS buoys have been measuring the swell at 7 to 8 ft. The next pulse of northwest swell will reach the islands on Wednesday, then build into early Thursday. A High Surf Advisory (HSA) is currently in effect for most north and west facing shores from Kauai to Maui, and an upgrade to a High Surf Warning will likely be needed for late Wednesday and Thursday. North and west shore surf will drop below advisory levels late Friday through the weekend. Another pulse of northwest swell may produce advisory level surf early next week.

Surf along east facing shores will be remain below seasonal average for the next few days, then pick up. Strong northeast winds along the front that will stall near Kauai will likely send large, short period swells to Kauai and Oahu, with east shore surf dropping down to near or below seasonal average during the weekend.

A Small Craft Advisory (SCA) will likely be needed on Wednesday and Thursday as the building northwest swell pushes seas in most areas above 10 ft. The SCA may need to be expanded for locally strong trade winds Thursday night of Friday. Border line SCA conditions are due on Saturday for both seas and local winds, though stronger trades will probably require an SCA Sunday onward.

HFO WATCHES/WARNINGS/ADVISORIES. High Surf Advisory until 6 PM HST Wednesday for Niihau-Kauai Windward-Kauai Leeward-Waianae Coast-Oahu North Shore-Oahu Koolau-Olomana-Molokai-Maui Windward West-Maui Central Valley- Windward Haleakala.
