summary

High pressure building upstate in the wake of a cold front will keep the weather cold and windy through the weekend. Some rainy weather will persist over the windward Big Island this morning with conditions expected to improve this afternoon. Elsewhere, mostly dry weather will prevail. The air mass will gradually moisten tonight and Sunday, bringing trade rain back. The remnants of the old front will bring rainy weather to leeward areas Sunday night into Monday and will send more rain to leeward communities as well. Trading is expected to be breezy to locally breezy Monday afternoon into Wednesday, before calming down at the end of the work week. Rain will continue to benefit the slopes and leeward coasts.

discussion

Currently at the surface, a strong cold front has moved south of the Big Island, while a high of 1,031 millibars is centered 750 miles northwest of Kauai. Breezy to gusty trades from the northeast across the island chain early this morning, bringing cooler conditions with temperatures now reaching the 50s in most areas except the windward Big Island. Infrared satellite images show mostly cloudy conditions in leeward areas, with mostly clear to partly cloudy skies in leeward areas. Radar images and rain gauge observations show that the majority of shower activity is now confined to the leeward slopes of the Big Island, with some residual showers across Maui County, and dry conditions elsewhere. The main short-term focus remains on strong winds over the next two days.
A strong rise will build up to the northwest and northeast and strengthen over the next couple of days. Windy conditions are expected statewide through the weekend as winds shift from the northeast to the more common east and northeast trade wind direction. Based on the latest monitoring trends, the wind warning appears to be handling the current situation well, and remains in place for the entire island chain until 6pm on Sunday.
The high will slowly settle southward northeast of the state Monday into Wednesday, keeping the refreshing breeze of locally gusty easterly circulations blowing across the island chain. An extended wind warning may be needed for some normally windy areas of Maui County and the Big Island on Monday and Tuesday. The rally will then weaken in the second half of next week as two fronts approach from the northwest. This will gradually ease the trade winds from west to east across the island chain.
As for the remaining weather details, excess moisture behind the front will continue over the leeward Big Island this morning, keeping rainy conditions at bay, with conditions expected to improve in the afternoon. Elsewhere, a dry air mass will keep rain activity minimal, with only a few light showers possible along leeward slopes. Strong winds combined with dew points in the 50s will make it very cold, with temperatures peaking in the mid-70s in most areas to around 80 degrees over the leeward Big Island.
The boundary layer will begin to moisten tonight as the NE Trade Feet expands with lapse rates in the 1000-900 MB layer at an impressive 9-10°C. This is expected to lead to a gradual increase in trade wind showers overnight. Little change in this pattern is expected through Sunday, with rain favoring windward slopes and coastlines, although strong trades may bring some downwind rain. Models show a band of moisture associated with the old front moving through Sunday night into Monday morning, which will likely lead to an increase in trade wind showers and send them downwind more frequently as well. Fairly typical trade wind weather should continue Monday afternoon into Wednesday, with rain favoring leeward slopes and coastlines, and some rain reaching leeward areas from time to time. With flow moving toward the east and southeast late next week, rain will continue to favor leeward areas, with afternoon clouds and a few showers expected each day in leeward areas.

Today, a cold front will advance over the south and east of the state and leave the region. Behind the front, a drier air mass, along with strong and gusty north-northeast winds, will blow across the state. This flow is likely to cause moderate-tempo turbulence along all mountain ranges. See AIRMET TANGO for more details.
Scattered showers may affect areas along the leeward portions of the smaller islands with isolated showers for the leeward portions of the Big Island.
AIRMET SIERRA remains in force to the north across eastern portions of the Big Island above 2,500 feet due to mountain blocking from low clouds and showers.
AIRMET TANGO remains in effect below 10,000 feet directly south across the western mountains on all islands.

Strong northeasterly winds to the storm associated with high pressure buildup will continue north of the state today, then move out of the east Sunday into early next week. A combination of short-term rough wind waves in response to these winds and a large swell from the northeast moving through support continued hazardous marine conditions in all Hawaiian waters through early next week. Storms are expected on the windier channels between Maui County and the Big Island, the leeward waters of Maui County, Maalaea Bay (north winds), and on the waters surrounding the south point of the Big Island through early Monday. The strong easterly trade will continue Monday through Wednesday, then will likely begin to ease and shift east-southeast late next week as the ridge begins to weaken.
Waves along exposed north- and east-facing beaches will remain rough due to a combination of locally driven wind waves and a large medium to long wave from the northeast (020°) moving through. Observations on nearby and offshore buoys reflect this and seas appear much higher than expected this morning, which is typical of this scenario. Waves will remain at warning levels for northern exposures today, then will likely drop to advisory levels on Sunday as winds shift from the east and north-northeast winds slowly subside. For east-facing beaches, where warning and advisory thresholds are lower compared to north-facing beaches, expect the warning to last through Sunday before dropping to advisory levels through Monday.
Waves along north- and west-facing beaches will trend higher late Sunday into early next week with a long wave (forerunners expected to arrive during Sunday) reaching the northwest (310-320 degrees). This swell will peak on Monday (foreshadowing surfing near warning level), then decline on Tuesday during the second half of the week. For the long term (low confidence), guidance indicates the arrival of a large northwesterly wave coming late next weekend (2/11).
